How Are Ketones Measured In Urine

Quantitative Measurement Of Ketone Bodies In Urine Using Reflectometry.

Quantitative Measurement Of Ketone Bodies In Urine Using Reflectometry.

Abstract BACKGROUND: Recently, automated urine test strip readers became available that can report quantitative data. We explored the possibility of measuring all ketone bodies (acetone, acetoacetate, 3-hydroxybutyrate) in urine with these test strips. Monitoring urinary ketone concentrations could offer the advantages of measuring higher values (due to the low renal thresholds) and being less sensitive to fluctuations. METHODS: We evaluated URISYS 2400 (Roche) quantitative reflectance data for the ketone reflectance field and compared it with biochemical data from urine samples. Using an easy sample pre-treatment with 3-hydroxybutyrate dehydrogenase, we were able to assay 3-hydroxybutyrate as well, which normally does not react on urine test strips. RESULTS: Within- and between-run reproducibility of the reflectance signal for high- and low-concentration urine pools was 11.0-3.6% and 11.0-5.8% for aceto-acetate, 8.2-9.2% and 10.4-16.1% for acetone, and 5.1-3.0% and 5.6-3.5% for 3-hydroxybutyrate, respectively. The lower limit of detection for acetoacetate was 0.13 mmol/L (CV=3.6%). Fair agreement was obtained between test strip data for ketones andcolorimetrically determined acetoacetate values (r=0.90). CONCLUSIONS: In urine test strip analysis, quantitative ketone reflectance data allow a simple and fast analysis, offering affordable screening for the detection of ketone body production in diabetes, especially in emergency settings.

Ketone Testing: What You Need To Know

Ketone Testing: What You Need To Know

What are ketones? Ketones are produced when the body burns fat for energy or fuel. They are also produced when you lose weight or if there is not enough insulin to help your body use sugar for energy. Without enough insulin, glucose builds up in the blood. Since the body is unable to use glucose for energy, it breaks down fat instead. When this occurs, ketones form in the blood and spill into the urine. These ketones can make you very sick. How can I test for ketones? You can test to see if your body is making any ketones by doing a simple urine test. There are several products available for ketone testing and they can be purchased, without a prescription, at your pharmacy. The test result can be negative, or show small, moderate, or large quantities of ketones. When should I test for ketones? Anytime your blood glucose is over 250 mg/dl for two tests in a row. When you are ill. Often illness, infections, or injuries will cause sudden high blood glucose and this is an especially important time to check for ketones. When you are planning to exercise and the blood glucose is over 250 mg/dl. If you are pregnant, you should test for ketones each morning before breakfast and any time the blood glucose is over 250 mg/dl. If ketones are positive, what does this mean? There are situations when you might have ketones without the blood glucose being too high. Positive ketones are not a problem when blood glucose levels are within range and you are trying to lose weight. It is a problem if blood glucose levels are high and left untreated. Untreated high blood glucose with positive ketones can lead to a life-threatening condition called diabetic ketoacidosis (DKA). What should I do if the ketone test is positive? Call your diabetes educator or physician, as you may need additional Continue reading >>

How To Detect Ketosis

How To Detect Ketosis

How can you tell if your low-carbing efforts have been effective enough to induce ketosis? Learn how to check your ketones! The state of ketosis The state of ketosis means that the body has switched from depending on carbohydrates for energy to burning fats for fuel. This means not only dietary fats (olive oil, guacamole, deep-fried pig ears), but also all the jiggly bits around your waist — clearly a desirable state for anyone looking to shed extra weight. When the body metabolizes fat, it generates molecules called ketones (also known as ketone bodies). As you restrict carbohydrate intake and amp up the dietary fat, more fat is metabolized and a greater quantity of ketones are created. Most of the cells in your body — including those in your brain — are able to use ketones for energy, although many people experience a few days’ adjustment period, often called the low carb flu. One of the varieties of ketones generated — acetone — cannot be used by the body and is excreted as waste, mostly in the urine and the breath. Conveniently, this makes it very simple to measure whether or not you are in ketosis. Upon entering ketosis, some people report a distinct change in the smell of their breath as a result of the extra released acetone. It could be “fruity” — it’s been likened to overripe apples — or even “metallic.” If you notice this happening during your first few days of changing your diet, it could be a good sign you’re in ketosis. The unusual smell isn’t anything dangerous, but it could be annoying. Drinking plenty of water should help, or get yourself some sugar-free gum. Most people report “keto-breath” diminishing after the first few weeks. Detecting ketones in urine The more accurate way — and the one we recommend — to check f Continue reading >>

Ketones Urine Test

Ketones Urine Test

Definition A ketone urine test measures the amount of ketones in the urine. Alternative Names Ketone bodies - urine; Urine ketones; Ketoacidosis - urine ketones test; Diabetic ketoacidosis - urine ketones test How the Test is Performed Urine ketones are usually measured as a "spot test." This is available in a test kit that you can buy at a drug store. The kit contains dipsticks coated with chemicals that react with ketone bodies. A dipstick is dipped in the urine sample. A color change indicates the presence of ketones. This article describes the ketone urine test that involves sending collected urine to a lab. A clean-catch urine sample is needed. The clean-catch method is used to prevent germs from the penis or vagina from getting into a urine sample. To collect your urine, the health care provider may give you a special clean-catch kit that contains a cleansing solution and sterile wipes. Follow instructions exactly so that the results are accurate. How to Prepare for the Test You may have to follow a special diet. Your provider may tell you to temporarily stop taking certain medicines that may affect the test. How the Test will Feel The test involves only normal urination. There is no discomfort. Why the Test is Performed Ketone testing is most often done if you have type 1 diabetes and: Your blood sugar is higher than 240 mg/dL Nausea or vomiting occur Pain in the abdomen Ketone testing may also be done: You have an illness such as pneumonia, heart attack, or stroke Nausea or vomiting that does not go away You are pregnant Normal Results A negative test result is normal. Normal value ranges may vary slightly among different laboratories. Some labs use different measurements or test different samples. Talk to your provider about the meaning of your specific test re Continue reading >>

Ketoacidosis

Ketoacidosis

Ketones in the urine, as detected by urine testing stix or a blood ketone testing meter[1], may indicate the beginning of diabetic ketoacidosis (DKA), a dangerous and often quickly fatal condition caused by low insulin levels combined with certain other systemic stresses. DKA can be fixed if caught quickly. Diabetics of all species therefore need to be checked for ketones with urine testing stix, available at any pharmacy, whenever insulin level may be too low, and any of the following signs or triggers are present: Ketone Monitoring Needed: Little or no insulin in last 12 hours High blood sugar over 16 mmol/L or 300 mg/dL (though with low insulin, lower as well...) Dehydration (skin doesn't jump back after pulling a bit gums are tacky or dry)[2] Not eating for over 12 hours due to Inappetance or Fasting Vomiting Lethargy Infection or illness High stress levels Breath smells like acetone (nail-polish remover) or fruit. Note that the triggers and signs are somewhat interchangeable because ketoacidosis is, once begun, a set of vicious circles which will make itself worse. So dehydration, hyperglycemia, fasting, and presence of ketones are not only signs, they're also sometimes triggers. In a diabetic, any urinary ketones above trace, or any increase in urinary ketone level, or trace urinary ketones plus some of the symptoms above, are cause to call an emergency vet immediately, at any hour of the day. Possible False Urine Ketone Test Results Drugs and Supplements Valproic Acid (brand names) Depakene, Depakote, Divalproex Sodium[3] Positive. Common use: Treatment of epilepsy. Cefixime/Suprax[4] Positive with nitroprusside-based urine testing. Common use: Antibiotic. Levadopa Metabolites[5] Positive with high concentrations[6]. Tricyclic Ring Compounds[7][8] Positive.

A Detailed Guide On How To Test Your Ketone Levels

A Detailed Guide On How To Test Your Ketone Levels

I have to be honest with you. I’ve been making some critical mistakes. I was assuming that I was in ketosis for months but I’m now finding out that isn’t the case. Not even close. I’ve finally hunkered down and have been measuring my ketones the right way and the results have been pretty surprising. I was eating too much protein, and too little fat. I was eating too frequently. I was eating too few calories. I never would have known this without testing. Time for you to learn from the mistakes I made and test the right way. Ketosis can be a powerful nutrition approach to use switch your metabolism to prioritize for fat loss, mental output, physical performance, and much more. The main problem? Many people just assume that if they are “low carb” they are in ketosis, but think again. How do you know if you’re actually in ketosis? As I love to say, “test, don’t guess” when it comes to your health. (Still trying to get “track, don’t slack” to catch on…) I’ll outline in this article the three ways to test your ketone levels and which you should be doing when. HOW TO TEST YOUR KETONE LEVELS: THREE DIFFERENT WAYS There are three testing methods because there are three forms of ketones in your body: acetate, acetoacetate, and beta-hydroxybutryate. Each of these ketone bodies do slightly different things and are in different forms, so they can be tested individually with different methods. The three different area these ketones exist in your body are your breath, urine or blood. The good news is that all of these ketone level measurements can be done at home, by yourself. You don’t need to go to a lab or use any fancy high-tech gadgetry. Tracking consistently, at least when you’re getting used to a ketogenic diet, is important so you know how mu Continue reading >>

5 Ways To Measure Your Ketones

5 Ways To Measure Your Ketones

5 Ways to Measure Your Ketones A ketogenic diet is a very low carbohydrate, moderate protein and high fat based nutrition plan. A ketogenic diet trains the individual’s metabolism to run off of fatty acids or ketone bodies. This is called fat adapted, when the body has adapted to run off of fatty acids/ketones at rest. Research has demonstrated that this nutrition plan improves insulin sensitivity and reduces inflammation throughout the body. This leads to greater fat metabolism and muscle development as well as a reduced risk of chronic disease. (1, 2). I get asked all the time how to measure the state of ketosis. There are several major ways and we will discuss those in this article. Measuring Your Ketones There are three types of ketone bodies: Acetone, Acetoacetate and Beta-Hydroxybutryate (BHB). Each of these three can be tested as acetone is a ketone released through the breath, acetoacetate is a ketone released through urine and BHB is (although not technically a ketone it acts like a ketone) in the blood stream and used by the cells for energy. 1. Blood Ketone Meter This measures BHB and is considered to be the most accurate way to measure ketone bodies. These have the ability to determine the ketone level in your blood precisely but they are also pricey and invasive. Personally, I freak out every time I have to prick my finger!! The Precision Xtra blood glucose and ketone meter is a good buy at $28-$30. The expensive part is the ketone test strips here which can cost $4 each. If you are looking at testing yourself every day it is going to cost you $120 a month and the $30 meter. Here is a starter kit you can get on Amazon Most people will enter into a light nutritional ketosis (between 0.5-1.0 mmol/L on the meter) within two or three days. It typically takes Continue reading >>

How To Measure Ketones And Optimize Ketogenic Diets

How To Measure Ketones And Optimize Ketogenic Diets

The problem with diets is that we think that one diet should be good for everyone. But research and N=1 experiments show that’s not the case. Learn about measuring ketones and ketosis to understand how your low carb or high fat diet is really affecting you. If there is one area of our bodies that is debated to extremes, with literally hundreds of differing strong opinions on it, it’s nutrition. For many, beliefs about nutrition and diet are tribal. We put ourselves in different camps and we war agains the other camps. Whether it be paleo, low fat, low carb, Atkins, high fat, low protein, vegan, raw vegan and so on. It’s exactly this sort of area where I see data as essential. Without data we have no hope of cutting through the maze of opinions to get to what really works. Part of the problem with nutrition and diets is that we tend to think that one diet should be good for everyone. But increasingly, research and N=1 experiments, are showing that that isn’t the case. And this is exactly why you should pay attention to today’s show. Today, we’re looking at what has relatively recently become the fastest growing nutrition or diet trend. The high fat diet. Also known in different guises as the ketogenic diet, or the low carb diet. And specifically how this can affect our different individual biochemistries, how we can measure “Ketosis” and other biomarkers to understand how our specific biology is reacting to it… and allowing us to troubleshoot and course correct when it isn’t getting the desired results we’re looking for from it. Today’s guest is Jimmy Moore. In 2004, Jimmy, at 32 years, weighed 410 pounds. Since then he has transformed his own biology, shedding all that additional weight with low carb and ketogenic diets. He has also interviewed n Continue reading >>

Ketones In Urine – How To Test And What Levels Are Optimal

Ketones In Urine – How To Test And What Levels Are Optimal

There are likely two reasons you want to test the ketone levels in your urine: REASON 1 – you’ve got type one diabetes (or type two diabetes, in some cases) and you need to test the ketones levels in your urine to help you avoid ketoacidosis. If that’s the case, skip down to the sections on… Then, skip straight to the section on… REASON 2 – you’re on the Keto diet and you want to use urine strips to check if you’re in ketosis. If that’s the case, then don’t worry we’ll also cover: But skip the section on ketoacidosis – it doesn’t apply to you unless you’re diabetic!

Testing Laboratory Microbiology - Air Quality - Mold Asbestos - Environmental - Lead emsl.com What are ketones? First things first – a quick 101 intro on what ketones actually are: Ketone bodies (or ketones) are produced by your liver during the break down of fatty acids when your body is low on glucose. Your body then uses these ketone bodies as fuel. You see, your cells can’t directly use the fatty acids in your fat stores to produce energy. And that’s because those fatty acids are unable to pass through the membrane which surrounds your cells. And if they can’t get inside? They can’t be used as fuel. So there’s an extra step to the process: First, the fatty acids travel to your liver where they’re broken down into ke Continue reading >>

How To Test Your Urine For Ketones

How To Test Your Urine For Ketones

Are you on a diet where part of the goal is to be "in ketosis"? Some diets, such as the Atkins Diet, recommend testing to find out whether your body is generating ketones. The easiest and least expensive way to do this is to test your urine using Ketostix or a similar testing strip. Although it is not the most accurate method, it can be helpful for home testing, especially when you're new to a ketogenic diet. Testing can be a useful way to tell if you are eating something that is higher in carbohydrate than you realized. Since different people will be in nutritional ketosis with different amounts of carbohydrate (and sometimes protein), it can provide information to help you individualize your diet. It also provides motivation to stay in ketosis. Two Notes About Testing for Ketones Diabetics testing ketone levels to check for ketoacidosis will interpret the reading much differently than someone on a ketogenic diet who desires higher levels of ketones. A reduced-carb diet does not have to be ketogenic to be helpful. Many studies of non-ketogenic low-carb diets have been found to have many benefits. How to Use Ketone Testing Strips In order to test your urine, you will need ketone urine testing strips. There are many brands available, such as Ketostix and Chemstrip. The name "Ketostix" is often used to refer to any ketone testing strip, no matter the manufacturer. When you're ready to test, follow these steps: You can either pass the test end of the strip through your urine as you urinate (be sure to wet it entirely), or collect urine in a clean, dry container and dip the test strip in. Shake off excess drops of urine. Wait for 15 seconds or whatever time is stated on the brand of test strips you are using. Compare the color on your strip to the color array on the side of Continue reading >>

How To Know If You’re In Ketosis: A Guide To Testing Ketone Levels

How To Know If You’re In Ketosis: A Guide To Testing Ketone Levels

Ketosis can be a powerful way to use your metabolism for fat loss, mental output, physical performance as well as many other health benefits. But how do you know if you’re actually in ketosis? As the old adage goes “test, don’t guess” when it comes to your health. In this guide, we’ll show exactly how to test your ketone levels to know if you’re in ketosis so you can make sure you’re getting all of the benefits that ketosis has to offer. There are three primary forms of ketones in your body, acetone, acetoacetate, and beta-hydroxybutryate. Each of these compounds do different things in the metabolism of ketosis and can be tested individually with differing techniques. Not all measurement is created equally, however, and some can be better than others for different purposes or times. The three different ketone bodies can be measured when they spill over into three different areas of your body: your breath, urine or blood. The good news is that all of these ketone level measurements can be done at home, by yourself. You don’t have to go to any lab or use any fancy high tech equipment. Tracking diligently, at least when you’re getting used to ketosis based diets, is important so you know how much you react to different variables like exercise, type and amount of food, and amounts of exogenous ketone supplements. Also, the optimal level of ketones for specific goals can vary per person. Knowing the amount where you thrive in the goal you want to achieve (and consistently checking if you’re hitting that amount) is the fastest way to reach your goals. Testing levels of ketones with urine strips (acetoacetate) One of the ketone bodies, acetoacetate, can be measured directly in the urine if they are in excessive levels.

Monitoring For Compliance With A Ketogenic Diet: What Is The Best Time Of Day To Test For Urinary Ketosis?

Monitoring For Compliance With A Ketogenic Diet: What Is The Best Time Of Day To Test For Urinary Ketosis?

Go to: Methods The KetoPerformance study with its before-and-after comparison design was registered at germanctr.de as DRKS00009605 and took place from February to June 2016. Exclusion criteria included underweight, obesity, kidney stones, pregnancy, diabetes mellitus and any fatty acid-metabolism disorders. The study protocol was approved by the Ethics Commission of the Albert-Ludwig University Freiburg (494/14) and all subjects signed a written consent form. Twelve of the 42 subjects from the KetoPerformance study could be recruited for the present substudy. Experimental design and dietary intervention The experimental intervention consisted of a KD without caloric restriction lasting 6 weeks with a previous preparation period including detailed instructions during teaching classes and individual counselling by a dietitian. The subjects were free to follow a KD according to their personal preferences but were advised to reach a ratio by weight of approximately 1.8:1 fat to carbohydrate and protein combined, yielding a diet with 80, 15, and 5 % of total energy intake from fat, protein and carbohydrate, respectively. During the KD intervention's sixth week, our substudy subjects were instructed to measure urine and blood ketone concentrations at regular intervals in as close proximity as possible during a 24-h period from 07:00 to 07:00 in the morning. During the day (07:00 till 22:00) blood and urinary ketones were measured every full hour and every three hours, respectively. During the night, blood and urinary ketones were measured once at 03:00. In total blood and urine and ketones were measured 18 and 8 times, respectively, and were recorded in a table sheet. Subjects were asked to drink 400 ml of water every 3 h during the day to ensure sufficient urination and to Continue reading >>

Urine Ketones

Urine Ketones

Ketones are produced when the body burns fat for fuel. Normally these ketones will be completely broken down (metabolised) so that there are very few ketones in the urine. If for any reason the body cannot get enough glucose for energy it will switch to using body fats, causing an increase in ketones in the body. This results in more ketones present in the urine. What are ketones? Ketones are produced when the body burns fat for energy. Normally, your body gets the energy it needs from carbohydrate in your diet. But stored fat is broken down and ketones are made if your diet does not contain enough carbohydrate to supply the body with sugar (glucose) for energy or if your body can't use blood sugar (glucose) properly. Ketones are usually formed in the liver and are broken down so that very small amounts of ketones appear in the urine. However, when carbohydrates are unavailable (for example, in starvation) or can't to be used as an energy source (for example, in diabetes), fat becomes the main source of energy and large amounts of ketones are made. Therefore, higher levels of ketones in the urine indicate that the body is using fat as the major source of energy. High levels of ketones in your body can cause tummy (abdominal) pain, feeling sick (nausea), being sick (vomiting) and diarrhoea. The ketones that most often appear in the urine when fats are burned for energy are called acetoacetate and beta-hydroxybutyric acid. What are the causes of ketones in the urine? The causes of high levels of ketones and therefore ketones in your urine include: Diabetic ketoacidosis (DKA). Starvation: not eating for prolonged periods (for example, 12 to 18 hours). Ketogenic diet (high-fat, low-carbohydrate diet). This can cause an increase in body ketones but much less than DKA and not Continue reading >>
