How Do You Test For Ketones?

Diabetes: Ketone Testing

Diabetes: Ketone Testing

www.CardioSmart.org Not having enough insulin can keep your body from using sugar for energy, even when your blood sugar level is very high. Instead, your body has to break down fats to get the fuel it needs. The fats are broken down into a type of acid which, if it builds up, can cause serious problems with vital organs. These acids are called ketones. When ketone levels get high, your kidneys release them into your urine. Having large amounts of ketones can be a sign of diabetic ketoacidosis. This is a dangerous condition caused by a lack of insulin. When to test for ketones Test for ketones whenever: • You feel sick to your stomach, are vomiting, or have belly pain. • You have an illness or infection. • You are dehydrated. • Your blood sugar is higher than the level your doctor set for you (for example, above 300). • You have missed a dose of your diabetes medicine. • You have symptoms of high blood sugar. • You are pregnant. Ask your doctor about testing for ketones during pregnancy. Symptoms of high blood sugar If you have mild high blood sugar, you may feel very thirsty and may urinate more, especially at night. Your skin may be warm and dry. If you have moderate high blood sugar, your breathingmay be fast and deep. Your breath may have a fruity odor. You may lose your appetite and have stomach pain and vomiting. You may become dizzy and weak when you sit or stand. Your urine may be dark, and you may urinate less. Your vision could become blurred. If you have severe high blood sugar, you may have rapid, deep breathing with a strong, fruity breath odor. You may feel very sleepy and weak, and you may faint. You may have a fast heart rate and a weak pulse. This is a very dangerous condition. How to test for ketones Blood test Continue reading >>

How Can I Do A Self-test For Ketones In My Urine In Diabetes?

How Can I Do A Self-test For Ketones In My Urine In Diabetes?

To do a self-test for ketones -- acids that your body produces when it is not getting enough fuel to function properly -- ask your doctor to recommend the best test kit and to review with you how to use it correctly. Also read the package insert carefully. For most tests, you will either need to urinate on a test strip or dip the strip into a urine sample collected in a clean container. Follow the directions to wait for the test strip to change colors and then compare your test strip to a color chart, which indicates the level of ketones in your blood. Record your results. Call your doctor immediately if your ketone levels are moderate or high. Keeping a log of your results can help you and your doctor create the best plan for managing your diabetes. Urine tests are simple, but to get good results, you have to follow directions carefully. Check to be sure that the strip is not outdated. Read the insert that comes with your strips. Go over the correct way to check with your doctor or nurse. Here's how most urine tests go: Get a sample of your urine in a clean container. Place the strip in the sample (you can also pass the strip through the urine stream). Gently shake excess urine off the strip. Wait for the strip pad to change color. The directions will tell you how long to wait. Compare the strip pad to the color chart on the strip bottle. This gives you a range of the amount of ketones in your urine. Record your results. Your health care team may teach you how to test for ketones in your morning urine or in your blood. High levels of ketones are a sign that your body is using your body fat for energy instead of the food you eat. Using fat for energy is not recommended during pregnancy. Ketones may be harmful for your baby. If your ketone levels are high, your health ca Continue reading >>

What Are Ketone Test Strips?

What Are Ketone Test Strips?

When your blood sugar runs high for an extended period of time, your body turns to fat reserves in order to get the energy it needs. The byproduct of this process is ketones, which show up in your blood and urine. Ketones can indicate hyperglycemia, which can be a serious situation if not treated properly. Ketone test strips can help determine the level of ketones in either urine or blood. Testing ketones with a blood-based test strip that you insert in a meter is just like testing your blood sugar. Testing with a urine strip means you either collect a small sample of urine or urinate directly onto the strip. Though testing with blood might be more accurate, it is also much more expensive. That's why so many of those with diabetes chose to go with urine ketone test strips. Understanding ketone test strip results Urine ketone test strips are looking for acetoacetic acid in the urine. This acid reacts with nitroprusside, a chemical in the strip, to produce a color. This color corresponds with a chart that comes packaged along with your test strips, usually on the outside of the vial. Typically, the results include negative, trace, moderate or large ketones. Negative ketones are a good sign. Trace ketones mean you should treat your high blood sugar as you normally would. Moderate or large ketones mean that your blood sugar has been too high for a while. Take the test a second time to confirm, then give your doctor a call. Options for ketone test strips When choosing urine ketone test strips, keep in mind how often you will use them. Test strips in a vial must be used before the expiration date, which is typically within six months after opening the package. Test strips that are individually packaged in foil cost a bit more, but will last much longer than those in a vial. I Continue reading >>

What Are Ketones And Their Tests?

What Are Ketones And Their Tests?

A ketone test can warn you of a serious diabetes complication called diabetic ketoacidosis, or DKA. An elevated level of this substance in your blood can mean you have very high blood sugar. Too many ketones can trigger DKA, which is a medical emergency. Regular tests you take at home can spot when your ketone levels run too high. Then you can take insulin to lower your blood sugar level or get other treatments to prevent complications. What Exactly Are Ketones? Everyone has them, whether you have diabetes or not. Ketones are chemicals made in your liver. You produce them when you don't have enough of the hormone insulin in your body to turn sugar (or “glucose”) into energy. You need another source, so your body uses fat instead. Your liver turns this fat into ketones, a type of acid, and sends them into your bloodstream. Your muscles and other tissues can then use them for fuel. For a person without diabetes, this process doesn’t become an issue. But when you have diabetes, things can run out of control and you build up too many ketones in your blood. If the level goes too high, it can become life-threatening. Who Needs a Ketone Test? You might need one if you have type 1 diabetes. In this type, your immune system attacks and destroys cells in your pancreas that make insulin. Without it, your blood sugar rises. People with type 2 diabetes can also get high ketones, but it isn't as common as it is with type 1. Tests can show you when your level gets high so you can treat it before you get sick. When Should You Test? Your doctor will probably tell you to test your ketones when: Your blood sugar is higher than 250 milligrams/deciliter (mg/dl) for two days in a row You're sick or you've been injured You want to exercise and your blood sugar level is over 250 mg/dl Continue reading >>

Urine Ketones - Meanings And False Positives

Urine Ketones - Meanings And False Positives

Professional Reference articles are written by UK doctors and are based on research evidence, UK and European Guidelines. They are designed for health professionals to use. You may find the Urine Ketones article more useful, or one of our other health articles. Description Ketones are produced normally by the liver as part of fatty acid metabolism. In normal states these ketones will be completely metabolised so that very few, if any at all, will appear in the urine. If for any reason the body cannot get enough glucose for energy it will switch to using body fats, resulting in an increase in ketone production making them detectable in the blood and urine. How to test for ketones The urine test for ketones is performed using test strips available on prescription. Strips dedicated to ketone testing in the UK include[1]: GlucoRx KetoRx Sticks 2GK® Ketostix® Mission® Ketone Testing should be performed according to manufacturers' instructions. The sample should be fresh and uncontaminated. Usually the result will be expressed as negative or positive (graded 1 to 4)[2]. Ketonuria is different from ketonaemia (ie presence of ketones in the blood) and often ketonuria does not indicate clinically significant ketonaemia. Depending on the testing strips used, urine testing for ketones either has an excellent sensitivity with a low specificity, or a poor sensitivity with a good specificity. However, this should be viewed in the context of uncertainty of the biochemical level of significant ketosis[3]. Interpretation of results Normally only small amounts of ketones are excreted daily in the urine (3-15 mg). High or increased values may be found in: Poorly controlled diabetes. Starvation: Prolonged vomiting. Rapid weight loss. Frequent strenuous exercise. Poisoning (eg, with isop Continue reading >>

Color Of Urine Strips For Ketosis

Color Of Urine Strips For Ketosis

Ketosis occurs when the body runs out of carbohydrates for energy. As a result, the body begins to process dietary and bodily fat to carry out necessary functions; the presence of ketones in urine thus indicates the metabolism of fat. Ketone testing strips evaluate the presence and concentration of ketones using a urine sample. Ketosis is evidenced by the a chemical reaction on the testing pad, which will change colors based on the concentration of ketones. Presence of Ketones The presence of ketones in urine may be surmised by a simple urinary test. Some test strips offer further evaluation of the presence of glucose, proteins or other material in urine. However, in testing for ketosis, strips need only to test for the presence of ketones. Use of Test Strip Urinary ketone test strips (or reagent strips) are simple to use. The testing pad, on one end of the test strip, is exposed to urine; it can be passed through a urine stream or dipped into a urine specimen. The testing pad contains a chemical that reacts in the presence of ketones, changing color depending on concentration. Ketone Readings For utmost accuracy, ketone readings should be conducted exactly 15 seconds after exposure to urine. On the testing bottle will be a small selection of colored squares demonstrating (in ascending order) what colors the test pad will turn in the event that ketones are present. Test Strip Readings Ketone test strips generally have five categories associated with ketone concentration in blood. A negative reading indicates no ketones are present in urine. Trace (5 mg/dL), small (15 mg/dL), moderate (40 mg/dL) and large (80 to 100-plus mg/dL) are the four positive ranges, indicated by a pale pink (trace) through deep burgundy (large) color on the test pad. Accuracy The testing pad may Continue reading >>

Point-of-care Blood Test For Ketones In Patients With Diabetes: Primary Care Diagnostic Technology Update

Point-of-care Blood Test For Ketones In Patients With Diabetes: Primary Care Diagnostic Technology Update

Go to: PREVIOUS RESEARCH Accuracy compared to existing technology The POC blood ketone test meter measures the ketone 3-beta-hydroxybutyrate (beta-OHB) in the blood of patients with diabetes. In comparison to the standard laboratory enzymatic method the ketone sensor accurately measured beta-OHB concentrations in patients with DKA (limits of agreement [LOA] 0.9 to 1.0 mmol/l) or starvation-induced ketonaemia (LOA-0.5 to +0.5 mmol/l).7 In an emergency department (ED) study of 173 hyperglycaemic patients, POC blood ketone tests were compared to urine dipstick analysis.8 Several cut-off points were evaluated. At a beta-OHB value <3 mmol/l or ketonuria ≤1+, ketoacidosis could be excluded (negative predictive value 100%). At 2+ cut-off points for ketonuria and at the 3 mmol/l cut-off point for ketonaemia the two tests had the same sensitivity (100%), but the specificity of beta-OHB (94%) was significantly higher (P<0.001) than that of ketonuria (77%). Overall the study showed that measurement of beta-OHB in capillary blood was faster and more effective than the use of urine dipsticks to detect ketoacidosis. A follow-up study by the same group on the correlation between urine and capillary blood ketones showed a good correlation for low values, but a poor correlation for high values. The study concluded that either test could be used to exclude ketosis, but that the capillary blood ketone test is more accurate to confirm ketoacidosis.9 A prospective observational study in an ED comparing ketone dipstick testing with capillary blood ketone testing, showed that the positive likelihood ratio (LR+) for DKA was 3 using urine ketone dipstick testing, and 4 for capillary blood ketone testing. In determining hyperketonaemia (both in diabetic ketosis and diabetic ketoacidosis) the L Continue reading >>

Ketosis & Measuring Ketones

Ketosis & Measuring Ketones

Generally, ketone concentrations are lower in the morning and higher in the evening. Whatever time you pick to measure ketone levels, make sure to keep it consistent. Also, do not measure your ketone levels right after exercise. Ketone levels tend to be lower while your glucose levels higher so you won't get representative numbers. Keep in mind there are daily fluctuations caused by changes in hormone levels. Don't get discouraged! Another aspect that affects the level of ketones is the amount of fat in your diet. Some of you may show higher concentration of ketones after a high-fat meal. Coconut oil contains MCTs that will help you boost ketones. To easily increase your fat intake on a ketogenic diet, try fat bombs - snacks with at least 80% fat content. Ketone levels tend to be higher after extensive aerobic exercise as your body depletes glycogen stores. Exercise may help you get into ketosis faster. ketogenic "fruity" breath is not pleasant for most people. To avoid this, drink a lot of water, mint tea and make sure you eat foods rich in electrolytes. Avoid too many chewing gums and mints, as it may put you out of ketosis; there may be hidden carbs affecting your blood sugar. Increase your electrolyte intake, especially potassium. You are likely going to lose some sodium and potassium when switching to the keto diet. Finally, if you find it hard to lose weight on a ketogenic diet, there may be plenty other reasons than the level of ketone bodies: Not Losing Weight on Low-Carb Ketogenic Diet? Don’t Give Up and Read Further. Continue reading >>

Test For Ketones

Test For Ketones

Topic Overview A ketone test checks for ketones in your blood or urine. Ketones are substances that are made when the body breaks down fat for energy. Normally, your body gets the energy it needs from glucose (sugar). If your body cannot use glucose for energy-for example, if your body doesn't make or use insulin-ketones are formed. You might also have ketones if you are not eating enough carbohydrates and your body uses fat for energy instead. Your body wants to get rid of ketones through urine. Ketones are most common in people who have type 1 diabetes. It is an early sign that there is not enough insulin, and blood sugar may be dangerously high. This can lead to diabetic ketoacidosis, a very serious medical problem. Blood ketones can be tested with some blood sugar meters. Urine ketones can be tested using specially prepared tablets or plastic strips. Continue reading >>

Testing For Ketones

Testing For Ketones

Testing for Ketones 3 Types of Ketones How to go about testing for Ketones? There are 3 types of ketone bodies. Acetone, Acetoacetate and Beta-Hydroxybutryate (BHB, though technically not really a ketone body) The body (the liver) converts long and medium chain fatty acids into BHB and Acetoacetate. BHB and Acetoacetate live in reversible equilibrium (they can transform back and forth). Acetoacetate can also be turned into acetone. After converted to acetone, it can not be converted back. Acetone is typically excreted through the urine or breath. If your body has been in ketosis for a while, you will see a reduction in acetoacetate. Muscles begin to use acetoacetate and turn it into Beta-Hydroxybutryate for fuel, so less is present in urine as you get more keto-adapted. This is the flaw of the urine test. It only tests for acetoacetate so it will go down as your body gets more efficient at using ketones for fuel. 3 Methods for Testing Ketones Urine strips only test acetoacetate. Ketonix only tests acetone in breath. Blood Strips test for Beta-Hydroxybutryate (BHB), what your body uses for fuel. 1. Urine Test Strips Pros: Cheap. Cons: Very inaccurate in testing level of ketosis. Our bodies excrete excess ketones in two ways. Through the urine or through the breath. When you are testing for ketones in urine you will typically see higher levels in early stages of a ketogenic diet because your body isn’t using ketones for fuel yet. After you are fully Keto-Adapted (2-4 weeks or so), you will see less and less ketones in your urine because your body in now using more ketones for fuel instead of excreting them through the urine or breath. The urine test strip is also very susceptible to changes based on your state of hydration. The more hydrated you are (and we should all b Continue reading >>

Why Do I Need To Test For Ketones?

Why Do I Need To Test For Ketones?

Ketones, Urine GENERAL INFORMATION: What are ketones? Ketones (KEY-tones) are formed when your body uses fat for energy. Glucose, the simplest form of sugar, is what your body is supposed to use for energy. Sometimes sugar cannot be used for energy and it stays in your blood. When sugar builds up in your blood, your body uses fat for energy. If you have diabetes, you may have seen the "check ketones" message on your glucose meter. This means your blood sugar is higher than it should be. Using fat for energy causes your body to make more sugar and ketones than the blood can hold. The kidneys start cleaning the extra sugar and ketones from your blood for removal in the urine. Having ketones in your blood or urine causes fruity smelling breath. This odor is sometimes mistaken for alcohol. Ask your caregiver for more information about diabetes. Why do I need to test for ketones? If your blood sugars have been high, your caregivers may want you to test for ketones. The results of this test may help them decide if your diabetes medicines need to be changed. How do I test for urine ketones? Ketone dipsticks are used for this test. A dipstick is a thin plastic strip that has a pad at the end of the strip with chemicals to test for ketones. The chemicals on the ketone dipsticks test pad turn purple when there are ketones in your urine. You can get ketone dipsticks at most drug stores. Follow the instructions that come with the ketone dipstick kit exactly. When choosing a Ketone test kit follow these guidelines: Read the label to be sure the test kit you are getting is FDA approved. Make sure the date on the test kit has not expired (passed). Be sure you store the test kit at the correct temperature and light conditions. Other tips that may help you with the test: The urine speci Continue reading >>

Evaluation Of A Nitroprusside Dip Test For Ketone Bodies

Evaluation Of A Nitroprusside Dip Test For Ketone Bodies

The detection of ketone bodies in urine specimens is sufficiently important to warrant the inclusion of a nitroprusside test for ketonuria as a part of the routine urinalysis. In the past, methods available have included a tablet test (Acetest) and the Rothera test, a conventional test tube procedure. Recently the nitroprusside test for urine ketones has been made available as a stick or dip test with a preparation called Ketostix. This test, like the other nitroprusside tests, depends on the reaction between acetoacetic acid and nitroprusside to produce a colored complex. In order to determine the accuracy and simplicity of the new test, it was compared with the two more standard procedures on a series of routine urine specimens in a general hospital laboratory. Tests were also carried out by experienced and inexperienced personnel on urines with and without added acetoacetic acid. The present report describes the results obtained in Continue reading >>

Ketones Urine Test

Ketone bodies - urine; Urine ketones; Ketoacidosis - urine ketones test; Diabetic ketoacidosis - urine ketones test A ketone urine test measures the amount of ketones in the urine. 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.
