Ketone bodies (ketones, KET) Legionella Testing Lab - High Quality Lab Results CDC ELITE & NYSDOH ELAP Certified - Fast Results North America Lab Locations legionellatesting.com Ketone bodies are metabolic end-products produced in the liver. They are acetone, acetoacetic acid and beta-hydroxybutyric acid. Ketone bodies are generally not found in the urine of healthy individuals, although small amounts of ketones are expelled from the body during urination throughout the day. Such concentrations cannot be detected by regular laboratory methods, so it is generally assumed that there are no ketone bodies in the urine of a healthy individual. Ketones are found in the urine in disorders of carbohydrate and fatty acid metabolism causing high levels of ketone bodies in the blood (ketonemia). A medical condition in which ketone bodies are present in the urine is called ketonuria. Under normal conditions, the body’s energy supply comes from glucose. Glucose accumulates in the body as glycogen. Above all, it accumulates in the liver. Glycogen forms a kind of energy storage which can be quickly mobilized if needed to compensate for a shortage of glucose. In response to a shortage of glucose, glycogen is converted by enzymes into glucose that gets into the bloodstream. As a result of physical exercise and emotional tension, diseases causing a high body temperature and other factors causing excessive energy expenditure, the stores of glycogen run out and the body starts to use its fat as a source of energy. Ketones are created when the body breaks down fats and then they are expelled during urination. Unlike adults, children have less glycogen stored and the body switches to fat as a source of energy sooner. As a result, their urinalysis shows ketonuria. High levels of ketone bodi Continue reading >>

Urine - For Ketone, Ketone Bodies (ketonuria)

Urine - For Ketone, Ketone Bodies (ketonuria)

Sample The is done on the urine. Indication It is advised in diabetic patients for the early diagnosis of ketoacidosis. To evaluate the diabetic patient in a coma. Definition Increased ketone bodies in blood are called Ketonemia. Increased excretion in the urine is called Ketonuria. Pathophysiology Ketone bodies are seen in case of decreased availability of carbohydrates like starvation or frequent vomiting. Another possibility is decreased utilization of carbohydrates like diabetes mellitus, and glycogen storage disease. High fat and low carbohydrates diet are ketogenic and increase ketone bodies in the blood. Ketones are the end product of fatty acid catabolism. Ketones are formed when the glucose as a source of energy is not present. This situation happens when there is no insulin so glucose cannot enter the cells. In that case, ketone bodies are the source of energy for the body, particularly to the brain. In case of fasting for 3 to 4 days, then 30 to 40% body energy is provided by the ketone bodies. Ketones bodies are the end product of fatty acid breakdown and consists of : Beta-hydroxybutyric acid. Acetoacetic acid. Acetone. The β- hydroxybutyric acid + acetoacetic acid readily converts to acetone. In the blood: Acetone is the minor amount. Acetoacetate and β- hydroxybutyrate are equal in amount and are the main ketone bodies. in a healthy person, ketones are formed in the liver but there is a negligible amount in urine. The outcome of Increased Ketones in the blood leads to : Electrolyte imbalance. Dehydration. If not corrected then leads to acidosis coma and ultimately death. Ketones are present in the urine when a threshold level of ketones exceed the normal level in the blood. Normal In Urine Ketone bodies are negative. Small amount = < 20 mg/dL. Moderate 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 >>

Ketones Urine Test

Ketones Urine Test

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. Continue reading >>

Ketonuria

Ketonuria

Ketonuria is a medical condition in which ketone bodies are present in the urine. It is seen in conditions in which the body produces excess ketones as an indication that it is using an alternative source of energy. It is seen during starvation or more commonly in type I diabetes mellitus. Production of ketone bodies is a normal response to a shortage of glucose, meant to provide an alternate source of fuel from fatty acids. Pathophysiology[edit] Ketones are metabolic end-products of fatty acid metabolism. In healthy individuals, ketones are formed in the liver and are completely metabolized so that only negligible amounts appear in the urine. However, when carbohydrates are unavailable or unable to be used as an energy source, fat becomes the predominant body fuel instead of carbohydrates and excessive amounts of ketones are formed as a metabolic byproduct. Higher levels of ketones in the urine indicate that the body is using fat as the major source of energy. Ketone bodies that commonly appear in the urine when fats are burned for energy are acetoacetate and beta-hydroxybutyric acid. Acetone is also produced and is expired by the lungs.[1] Normally, the urine should not contain a noticeable concentration of ketones to give a positive reading. As with tests for glucose, acetoacetate can be tested by a dipstick or by a lab. The results are reported as small, moderate, or large amounts of acetoacetate. A small amount of acetoacetate is a value under 20 mg/dl; a moderate amount is a value of 30–40 mg/dl, and a finding of 80 mg/dl or greater is reported as a large amount. One 2010 study admits that though ketonuria's relation to general metabolic health is ill-understood, there is a positive relationship between the presence of ketonuria after fasting and positive metabo Continue reading >>

Ketone Bodies (urine)

Does this test have other names? Ketone test, urine ketones What is this test? This test is used to check the level of ketones in your urine. Normally, your body burns sugar for energy. But if you have diabetes, you may not have enough insulin for the sugar in your bloodstream to be used for fuel. When this happens, your body burns fat instead and produces substances called ketones. The ketones end up in your blood and urine. It's normal to have a small amount of ketones in your body. But high ketone levels could result in serious illness or death. Checking for ketones keeps this from happening. Why do I need this test? You may need this test if you have a high level of blood sugar. People with high levels of blood sugar often have high ketone levels. If you have high blood sugar levels and type 1 or type 2 diabetes, it's important to check your ketone levels. People without diabetes can also have ketones in the urine if their body is using fat for fuel instead of glucose. This can happen with chronic vomiting, extreme exercise, low-carbohydrate diets, or eating disorders. Checking your ketones is especially important if you have diabetes and: Your blood sugar goes above 300 mg/dL You abuse alcohol You have diarrhea You stop eating carbohydrates like rice and bread You're pregnant You've been fasting You've been vomiting You have an infection Your healthcare provider may order this test, or have you test yourself, if you: Urinate frequently Are often quite thirsty or tired Have muscle aches Have shortness of breath or trouble breathing Have nausea or vomiting Are confused Have a fruity smell to your breath What other tests might I have along with this test? Your healthcare provider may also check for ketones in your blood if you have high levels of ketones in your urine Continue reading >>

Getting To Know Ketones

Getting To Know Ketones

People with diabetes, particularly those with Type 1 diabetes, have been at least vaguely aware of the word ketones for a long time. With the recent resurgence of popular interest in low-carbohydrate diets, however, just about everyone seems to be talking about ketones these days. But does anyone really know what ketones are? Are they a danger to your health (as in diabetic ketoacidosis), or a sign that you have lowered your carbohydrate intake enough to cause weight loss (as some people who follow low-carbohydrate diets believe)? What are ketones? Ketones are end-products of fat metabolism in the body. That is, they are formed when fat is burned for energy by the muscles. Chemically, they are acids known as ketone bodies, and there are three types: beta-hydroxybutyric acid, aceto-acetic acid, and acetone. But you don’t have to be a chemist to understand what role they play in the body. To get to know ketones, it’s helpful to understand how your body burns fuel. A simple analogy is that of an automobile. For a car engine to run, the engine must burn fuel (gasoline), and when the fuel is burned, exhaust (carbon monoxide) is created. The carbon monoxide is the end-product of gasoline combustion. Your body also has an engine that must burn fuel to operate. The engine is muscle, and the fuel is fat, carbohydrate (glucose), and, in certain conditions, protein. When fat is burned, the “exhaust” is ketones, and when glucose is burned, the “exhaust” is lactic acid. Fat is more desirable as a fuel than glucose because there are more calories in a gram of fat (9 calories per gram) than there are in a gram of glucose (4 calories per gram), so you get more energy per gram of fat burned. In a sense, you could call fat a high-test fuel. But there is one catch to burning f Continue reading >>

Ketone Bodies Urine Test

What are other Names for this Test? (Equivalent Terms) Ketonuria Urine Test What is Ketone Bodies Urine Test? (Background Information) Ketone bodies are chemical compounds produced when the body is unable to use carbohydrates. This occurs most often because of diabetes, malnutrition, or starvation Ketone bodies include acetone, acetoacetic acid, and beta-hydroxybutyrate. These 3 compounds are acidic and toxic Ketosis is the presence of ketone bodies in blood. Acidification of blood often accompanies ketosis because the abundance of acidic ketone bodies overcomes the blood’s alkaline reserves, turning the blood acidic Ketosis results in ketonuria, or the presence of ketone bodies in the urine, as excess ketone bodies pass through the kidneys into blood The Ketone Bodies Urine Test detects ketone bodies in the urine. It is used to diagnose ketosis and acidification of blood resulting from excess ketone bodies What are the Clinical Indications for performing the Ketone Bodies Urine Test? Following are the clinical indicators for performing the Ketone Bodies Urine Test: Following up to findings of low blood pH Trouble breathing Altered mental status Fatigue Rapid heart rate Severe dietary restriction of carbohydrates Vomiting Nausea Bad breath How is the Specimen Collected for Ketone Bodies Urine Test?

Preparation required: It is recommended to drink 6 to 8 glasses of water or other fluids prior to the test. What is the Significance of the Ketone Bodies Urine Test Result? A positive value for the Ketone Bodies Urine Test is associated with the detection of ketone bodies in urine Continue reading >>

Clinical Significance Of Positive Urine Ketone Result

Clinical Significance Of Positive Urine Ketone Result

Ketone bodies are usually absent in urine. The presence of ketones in the urine probably indicates that the body is using fats rather than carbohydrates for energy. High levels of ketones may be present in the urine of individuals with uncontrolled diabetes because the body's ability to metabolize carbohydrates is defective. Detecting the presence of ketones in the urine is a valuable aid to managing and monitoring individuals with diabetes mellitus. Ketonuria is an indication that the insulin dose needs to be increased. Electrolyte imbalance and dehydration occur when ketones accumulate in the blood. If these conditions are not corrected by adjusting the dose of insulin, the patient may develop ketoacidosis and ultimately diabetic coma. Low levels of ketones may be detected during conditions of physiological stress such as fasting, rapid weight loss, frequent strenuous exercise or prolonged vomiting. The presence of ketones in these situations is due to either inadequate intake of carbohydrates or increased loss of carbohydrates. Continue reading >>

Ketones

Ketones

Ketones are a beneficial product of fat metabolism in the body. When carbohydrate intake is restricted, it lowers blood sugar and insulin levels. As insulin levels fall and energy is needed, fatty acids flow from the fat cells into the bloodstream and are taken up by various cells and metabolized in a process called beta-oxidation. The end result of beta-oxidation is a molecule called acetyl-coA, and as more fatty acids are released and metabolized, acetyl-coA levels in the cells rise. This causes a sort of metabolic “feedback loop” which triggers liver cells to shunt excess acetyl-Coa into ketogenesis, or the making of ketone bodies. Once created, the liver dumps the ketone bodies into the blood stream and they are taken up by skeletal and heart muscle cells at rates of availability. In addition, the brain begins to use ketones as an alternate fuel when blood levels are high enough to cross the blood brain barrier. Testing Laboratory Microbiology - Air Quality - Mold Asbestos - Environmental - Lead emsl.com There are three major types of ketone bodies present in the human blood stream when the metabolic process of ketosis is dominant: Acetoacetate (AcAc) is created first β-hydroxybutyrate (BHB) is created from acetoacetate Acetone is a spontaneously created side product of acetoacetate In times of starvation, or a low carbohydrate intake resulting in low insulin levels, ketone bodies supply up to 50% of the energy requirements for most body tissues, and up to 70% of the energy required by the brain. Glucose is the main source of fuel for neurons when the diet is high in carbohydrates. But when carbs are restricted, ketogenesis becomes the primary fuel process for most cells. During fasting or low carbohydrate intake, levels of ketone bodies in the blood stream can Continue reading >>

Urine Test Types: Ph, Ketones, Proteins, And Cells

Urine Test Types: Ph, Ketones, Proteins, And Cells

Urine as a Diagnostic Tool A long time ago, disgusting as it may be, people used to actually taste and drink urine in order to try and diagnose a patient's disease! I'm not even kidding you. Thankfully, modern-day doctors do not have to resort to such disgusting and even dangerous methods. One of the reasons the doctor barbers of yesteryear used to drink their patient's urine was to see if it had a sweet taste, often indicative of diabetes mellitus. Finding the sweet-tasting glucose in the urine was covered in detail in another lesson, so we'll focus on other important measurements here instead. Interpreting Urine pH One value that can be measured in the urine is known as urine pH. pH is a measure of the acidity or alkalinity of a substance. If the pH is low, then it is acidic. If the pH is high, then it is basic, or alkaline. To remember which is which, I'll give you a little trick that has worked for me. If you grew up watching cartoons, you probably saw some comical ones where cartoonish robbers poured acid on the roof of a bank vault and waited while the acid ate its way downward into the vault, so the robbers could get down there to steal all the cash. If you can recall that acid likes to eat its way downward into things, then you'll remember that acidic substances go down the pH scale. That is to say, their pH numbers are lower than basic substances. Normal urine pH is roughly 4.6-8, with an average of 6. Urine pH can increase, meaning it will become more basic, or alkaline, due to: A urinary tract infection Kidney failure The administration of certain drugs such as sodium bicarbonate Vegetarian diets On the flip side, causes for a decreased, or acidic, urine pH, include: Metabolic or respiratory acidosis Diabetic ketoacidosis, a complication of diabetes mellitus 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 >>

What Are Ketones?

What Are Ketones?

What are ketones and what causes them? Ketones are the result of the body burning fat for energy or fuel. For a person with diabetes, ketones are often the result of prolonged high blood sugar and insulin deficiency. Without the right amount of insulin, glucose starts to build up in the blood stream and doesn't enter the cells. The cells burn fat instead of glucose, and ketones form in the blood and spill into the urine. Some causes of high blood sugar are: Missing an insulin dose or skipping some oral medications. A disconnected or blocked insulin pump tube. Being sick with the flu. High levels of stress. Eating more carbohydrates than your medication covers. What are the signs that I should test for ketones? Symptoms of high blood sugar include frequent urination, frequent thirst, blurry vision, dry mouth, vomiting, and fatigue. There are several scenarios that should prompt a test for ketones. If your blood sugar is over 240 mg/dl for two tests in a row. When you are ill. When your blood sugar is over 240 mg/dl and you are planning on exercising. If you are pregnant, you should test for ketones each morning before breakfast and whenever blood sugars are elevated. How do I test for ketones? There are two ways to test for ketones - by testing your urine or your blood. Ketones appear first in the blood stream and are later present in the urine, so testing your blood for ketones is the best way to check for an early problem. To check urine for ketones, you must collect a urine sample or dip a ketone test strip into a fresh stream of urine. After waiting for the time suggested by the ketone strip manufacturer, you compare the color strip to the chart on the bottle. The darker the color, the higher the amount of ketones in the urine. At this time, there are just a few mete Continue reading >>

Ketonuria (ketone Bodies In Urine)

Ketonuria (ketone Bodies In Urine)

Ketonuria (ketone bodies in urine) Ketonuria (ketone bodies in urine) - is revealing in the urine ketone bodies. Ketone bodies - acetone, acetoacetic acid and beta-hydroxybutyric acid in urine are found together. Normally, the urine stands 20-50 mg of ketone bodies per day, are not detected by conventional qualitative tests. Ketone bodies appear in urine in impairment of metabolism of carbohydrates, fats and proteins, which is accompanied by an increase in ketogenesis in the tissues and the accumulation of ketones in the blood (ketonemia). Ketonemia can also occur when: unbalanced diet pregnancy starvation fever alcohol intoxication poisoning infectious diseases (scarlet fever, influenza, meningitis) The urine ketone bodies appear in ketonemii. Ketonuria (ketone bodies in urine) in the postoperative period due to the collapse of the protein as a result of surgical trauma. In adults, ketonuria (ketone bodies in urine) is more common in severe diabetes. Ketonuria in diabetes develops due to enhanced ketogenesis and impairments ketoliza. Leads to increased ketogenesis increased mobilization of fat from adipose tissue, reducing the formation oksalatsetata in the Krebs cycle, reducing the biosynthesis of fatty acids. In severe diabetes, is accompanied by damage of kidney tissue (the cleavage site of ketones), there is an additional impairment ketolisys.
