Ketoacidosis How To Test

Diabetic Ketoacidosis Workup

Diabetic Ketoacidosis Workup

Approach Considerations Diabetic ketoacidosis is typically characterized by hyperglycemia over 250 mg/dL, a bicarbonate level less than 18 mEq/L, and a pH less than 7.30, with ketonemia and ketonuria. While definitions vary, mild DKA can be categorized by a pH level of 7.25-7.3 and a serum bicarbonate level between 15-18 mEq/L; moderate DKA can be categorized by a pH between 7.0-7.24 and a serum bicarbonate level of 10 to less than 15 mEq/L; and severe DKA has a pH less than 7.0 and bicarbonate less than 10 mEq/L. [17] In mild DKA, anion gap is greater than 10 and in moderate or severe DKA the anion gap is greater than 12. These figures differentiate DKA from HHS where blood glucose is greater than 600 mg/dL but pH is greater than 7.3 and serum bicarbonate greater than 15 mEq/L. Laboratory studies for diabetic ketoacidosis (DKA) should be scheduled as follows: Repeat laboratory tests are critical, including potassium, glucose, electrolytes, and, if necessary, phosphorus. Initial workup should include aggressive volume, glucose, and electrolyte management. It is important to be aware that high serum glucose levels may lead to dilutional hyponatremia; high triglyceride levels may lead to factitious low glucose levels; and high levels of ketone bodies may lead to factitious elevation of creatinine levels.

Diabetes: What Is Ketoacidosis And How Can Be Avoided & Treated?

Diabetes: What Is Ketoacidosis And How Can Be Avoided & Treated?

Good question! According to Wikipedia: Diabetic ketoacidosis is a potentially life-threatening complication in patients with diabetes mellitus. In order to define ketoacidosis a little better, let's go back to the source: diabetes. Someone who is diabetic is unable to produce insulin, a hormone necessary for the transfer of sugar from the bloodstream to the cells, which in turn produce energy. If this progression is disrupted, through lack of insulin for example, the body has to try to compensate by creating energy elsewhere. And so the body starts to burn fat and muscle to meet its energy needs. Unfortunately, this chemical reaction produces molecules known as ketone bodies. In small quantities, these are fine, and it is in fact normal to have traces of them in your blood (approximately 1mg/dl). However, if the quantity of ketones surpasses this threshold by too much, it starts to affect the pH of your blood (which becomes progressively more acidic). Even the slightest drop in pH can have dangerous effects: as the quantity of the ketones in your blood increases, and the blood pH diminishes, your kidneys start having problems. Eventually, if the ketoacidosis is left untreated, your kidneys can fail and you can die from dehydration, tachycardia and hypotension. A number of other symptoms can appear in extreme cases. Fortunately for us, the quantity of ketones has to be consequential, and it usually takes a while before individuals start manifesting symptoms. In my case, my diabetes went undiagnosed for a month and a half before it was discovered, and even then my ketone levels were relatively normal. If you're a diabetic, ketoacidosis can be easily avoided by controlling your blood sugar levels and maintaining a healthy lifestyle. Some doctors, preferring to stay on the Continue reading >>

Ketones Blood Test

Ketones Blood Test

Acetone bodies; Ketones - serum; Nitroprusside test; Ketone bodies - serum; Ketones - blood; Ketoacidosis - ketones blood test A ketone blood test measures the amount of ketones in the blood. How the Test is Performed How to Prepare for the Test No preparation is needed. How the Test will Feel When the needle is inserted to draw blood, some people feel slight pain. Others feel a prick or stinging. Afterward, there may be some throbbing or a slight bruise. This soon goes away. Why the Test is Performed Ketones are substances produced in the liver when fat cells break down in the blood. This test is used to diagnose ketoacidosis. This is a life-threatening problem that affects people who: Have diabetes. It occurs when the body cannot use sugar (glucose) as a fuel source because there is no insulin or not enough insulin. Fat is used for fuel instead. When fat breaks down, waste products called ketones build up in the body. Drink large amounts of alcohol. Normal Results A normal test result is negative. This means there are no ketones in the blood. Normal value ranges may vary slightly among different laboratories. Some labs use different measurements or test different samples. Talk to your health care provider about the meaning of your specific test results. What Abnormal Results Mean A test result is positive if ketones are found in the blood. This may indicate: Other reasons ketones are found in the blood include: A diet low in carbohydrates can increase ketones. After receiving anesthesia for surgery Glycogen storage disease (condition in which the body can't break down glycogen, a form of sugar that is stored in the liver and muscles) Being on a weight-loss diet Risks Veins and arteries vary in size from one person to another and from one side of the body to the other.

Diabetes Urine Tests

Diabetes Urine Tests

Urine tests may be done in people with diabetes to evaluate severe hyperglycemia (severe high blood sugar) by looking for ketones in the urine. Ketones are a metabolic product produced when fat is metabolized. Ketones increase when there is insufficient insulin to use glucose for energy. Urine tests are also done to look for the presence of protein in the urine, which is a sign of kidney damage. Urine glucose measurements are less reliable than blood glucose measurements and are not used to diagnose diabetes or evaluate treatment for diabetes. They may be used for screening purposes. Testing for ketones is most common in people with type 1 diabetes. Type 1 Diabetes: What Are The Symptoms? This test detects the presence of ketones, which are byproducts of metabolism that form in the presence of severe hyperglycemia (elevated blood sugar). Ketones are formed from fat that is burned by the body when there is insufficient insulin to allow glucose to be used for fuel. When ketones build up to high levels, ketoacidosis (a serious and life-threatening condition) may occur. Ketone testing can be performed both at home and in the clinical laboratory. Ketones can be detected by dipping a test strip into a sample of urine. A color change on the test strip signals the presence of ketones in the urine. Ketones occur most commonly in people with type 1 diabetes, but uncommonly, people with type 2 diabetes may test positive for ketones. The microalbumin test detects microalbumin, a type of protein, in the urine. Protein is present in the urine when there is damage to the kidneys. Since the damage to blood vessels that occurs as a complication of diabetes can lead to kidney problems, the microalbumin test is done to check for damage to the kidneys over time. Can urine tests be used to Continue reading >>

Diabetic Ketoacidosis

Diabetic Ketoacidosis

Diabetic ketoacidosis (DKA) is a serious problem that can occur in people with diabetes if their body starts to run out of insulin. This causes harmful substances called ketones to build up in the body, which can be life-threatening if not spotted and treated quickly. DKA mainly affects people with type 1 diabetes, but can sometimes occur in people with type 2 diabetes. If you have diabetes, it's important to be aware of the risk and know what to do if DKA occurs. Symptoms of diabetic ketoacidosis Signs of DKA include: needing to pee more than usual being sick breath that smells fruity (like pear drop sweets or nail varnish) deep or fast breathing feeling very tired or sleepy passing out DKA can also cause high blood sugar (hyperglycaemia) and a high level of ketones in your blood or urine, which you can check for using home-testing kits. Symptoms usually develop over 24 hours, but can come on faster. Check your blood sugar and ketone levels Check your blood sugar level if you have symptoms of DKA. If your blood sugar is 11mmol/L or over and you have a blood or urine ketone testing kit, check your ketone level. If you do a blood ketone test: lower than 0.6mmol/L is a normal reading 0.6 to 1.5mmol/L means you're at a slightly increased risk of DKA and should test again in a couple of hours 1.6 to 2.9mmol/L means you're at an increased risk of DKA and should contact your diabetes team or GP as soon as possible 3mmol/L or over means you have a very high risk of DKA and should get medical help immediately If you do a urine ketone test, a result of more than 2+ means there's a high chance you have DKA. When to get medical help Go to your nearest accident and emergency (A&E) department straight away if you think you have DKA, especially if you have a high level of ketones in Continue reading >>

Urine Test Kits

Urine Test Kits

What is the difference between the urine test kits for people with diabetes? Three different kinds of urine testing kits are available for testing three different substances in the urine: glucose (sugar), ketones, and microscopic amounts of protein (microalbuminuria). Glucose test kits Before the development of blood glucose meters, urine testing was the only method for gauging a person's sugar levels. However, it has always been a very imprecise method for testing glucose levels for a variety of reasons: Urine test strips cannot detect glucose (sugar) until the blood glucose level is above 180 mg/dl. This means a person's blood sugar level could still be high (hyperglycemia) or even dangerously low (hypoglycemia) but still not be detected. Urine glucose testing is highly subject to user error because it requires color interpretation of the urine test strip via a color-scale comparison. This becomes an issue with people who are colorblind or have poor eyesight, and certain drugs and vitamin C can change the color of the urine and thus provide an invalid measurement. The reading reflects the level of blood glucose from a few hours earlier - not at the present moment - and often is misinterpreted. As a result of these shortcomings, healthcare professionals recommend that anyone needing to closely monitor blood glucose levels use a blood glucose meter. However, urine strips can be useful in certain populations who physically cannot or will not test themselves with a blood glucose meter. Ketone test kits Ketone bodies are the byproducts of the body burning fat, rather than glucose, to provide energy. When fat is used for energy instead of glucose, the preferred fuel source, the liver produces substances called ketones. If ketones build up, they can lead to a life-threatenin Continue reading >>

What Was A Choice You Made That Completely Changed Your Life?

What Was A Choice You Made That Completely Changed Your Life?

I gave up pitching myself to everyone out there. When I graduated from the university, I had no clue what to do next. As well as thousands of young graduates who have to move to the next stage of their lives, I had to decide where to live, how to make money, and ultimately what direction to move in… I had no idea what decisions would let me not screw up my life. I was still looking for the passion and was still trying to understand what excites me the most. The only thing I felt passionate about was blogging. However, I realized that it wasn’t likely to let me make a living within the first year or two. Another thing I knew is that I have always wanted to be self-employed and run my own business. I had a decent amount of ideas that seemed great to me… however, I had no dedicated team and not enough savings to sustain a startup… Unfortunately, it didn’t seem feasible to launch a business. I had too many questions and no answers at all. I faced a few dilemmas and appeared to be not ready to solve them. Eventually, I kept blogging on a regular basis and as most people out there I decided to look for a job. The next month was all about pitching - every single day I sent resumes to dozens of different companies and tried to convince the editors of the authoritative outlets that my writing is worth sharing. No success. Neither companies were sending me job offers, nor anyone found my articles interesting enough. Over that month I received 37 job rejections and sent 78 unanswered emails asking to feature my articles on different publications and websites. At that point, I realized that my strong unwillingness to work in the corporate sector and my overall uncertainty about the field I want to work at were not likely to help me land a nice job. Moreover, frankly speak Continue reading >>

A Breath Test For Ketoacidosis

A Breath Test For Ketoacidosis

British investigators are researching a non-invasive breath test to quickly diagnose diabetic ketoacidosis. Diabetic ketoacidosis is a preventable acute complication of type 1 diabetes (DM). It develops rapidly upon interruption of insulin therapy, or when conditions develop that do not allow insulin to work (for example, acute illness). When someone with diabetes doesn't have enough insulin to burn glucose as fuel, their body can start breaking down fat instead. Ketones start building up in the bloodstream. Ketones are acid, and their accumulation in the blood may lead to diabetic ketoacidosis. Diabetic ketoacidosis may be lethal even in this day and age. Children, who depend on parental management of diabetes, are especially susceptible to diabetic ketoacidosis, but anyone with type 1 DM may get it. Home testing for ketones is available, however they currently require either a blood or urine sample. These tests differ from the standard blood sugar tests (fingerstick glucose test for A1c levels). Every patient with type 1 DM (or caregiver) is instructed to check for ketones whenever: • The child does not feel well • They become dehydrated • They have an interruption of insulin therapy • Their blood glucose testing reads high. For more information on how to avoid diabetic ketoacidosis. Researchers in England have developed a potentially easier way to monitor these ketone levels, and curiously enough, the trick may lie in a person's breath. Breath Test Detects Acetone In a recent study at Oxford Children's Hospital,1 researchers tested more than 100 patients with type 1 diabetes between the ages of 7 to 18 years old, measuring gases in their breath and ketone levels in their blood. Researchers found that one gas in particular—acetone— seemed to predict ketone Continue reading >>

New Quantitative Test Ketone Beta-hydroxybutyrate

New Quantitative Test Ketone Beta-hydroxybutyrate

Effective December 13, 2016, TriCore changed to a new quantitative test to measure ketones in plasma or serum. The new test, Ketone Beta-hydroxybutyrate (KETBHB), measures Beta-hydroxybutyrate (BHB) and is not directly comparable to the previous test measuring acetoacetate. BHB shows different clearance during treatment of ketoacidosis. As diabetic ketoacidosis (DKA) is treated, serum BHB decreases more consistently than acetoacetate which is converted to BHB and does not change as rapidly. CLINICAL UTILITY BHB is the predominate ketone present during DKA and trends with a patient’s clinical status. Because KETBH is quantitative, it can be used for monitoring ketosis to resolution. Additionally, BHB can be used to clinically diagnose and monitor the disease status or severity of alcoholism, glycogen storage disease, high fat/low carbohydrate diets, pregnancy, alkalosis, ingestion of isopropyl alcohol, and salicylate poisoning. In these situations the levels are usually above the normal range which is up to 0.27 mml/L, but often do not reach the threshold for DKA diagnosis. RESULTS INTERPRETATION FOR BETA-HYDROXYBUTYRATE LEVELS Range mmol/dL Interpretation Sensitivity for DKA Specificity for DKA <0.27 no ketoacidosis, normal range 0.28-1.5 DKA not entirely excluded, other conditions should be considered 1.5-3.0 children DKA possible in diabetics with >250mg/dL glucose 98-100% 78-93% 1.5-3.8 adults DKA possible in diabetics with >250mg/dL glucose 98-100% 78-93% >3.0 children >3.8 adults Near diagnostic of DKA in diabetic patient near 100% 93-94% 1. A Beta-hyroxybutyrate level of more than 1.5 mmol/L had sensitivity ranging from 98-100% and specificity ranging from 78.6-93.3% for the diagnosis of diabetic ketoacidosis in diabetic patients presenting to the Emergency Continue reading >>

Ketones Urine Test

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. Talk to your provider about the meaning of your specific test results. What Abnormal Results Continue reading >>

Testing For Diabetic Ketoacidosis Symptoms In Dogs

Testing For Diabetic Ketoacidosis Symptoms In Dogs

Diabetic ketoacidosis is an extreme form of hyperglycemia, during which ketones build up in the bloodstream. Ketoacidosis can be fatal, so it’s essential to contact your veterinarian as soon as symptoms arise. Symptoms can include vomiting, weakness, rapid breathing and the odor of acetone on the breath. Your veterinarian will perform a variety of tests to determine if your diabetic dog is suffering from ketoacidosis, including blood testing and urine dipsticks. Your dog might need to stay at the vet for around-the-clock monitoring. Blood Testing for Ketoacidosis Your veterinarian performs a blood test to determine if your dog is suffering from diabetic ketoacidosis. He collects a small amount of blood, testing it for high circulating blood sugar levels and blood pH levels, as well as phosphorus and potassium levels. Electrolyte levels can fluctuate, so he might perform several tests over a period of time to create a record of imbalances, as well as determine which intravenous fluids would best benefit your dog. Blood tests continue until your dog shows significant improvement. Urine Dipstick Test for Ketones While caring for your pet, the vet places a catheter inside the dog to collect urine. He tests the urine with a dipstick to perform a routine urinalysis, which he's likely to repeat many times during your dog’s emergency care stay. When a urine dipstick no longer reads positive for ketones, your dog is well on his way to recovery. Around-the-Clock Monitoring and Fluid Therapy During ketoacidosis, your dog’s cells experience a severe loss of glucose. This can be dangerous, so early detection is best. If possible, get your dog into a 24-hour care facility as soon as you notice symptoms. The vet closely monitors your dog, ensuring he is treated for any infection Continue reading >>

Exams And Tests For Diabetic Ketoacidosis

Exams And Tests For Diabetic Ketoacidosis

A A A Diabetic Ketoacidosis (cont.) The diagnosis of diabetic ketoacidosis is typically made after the health care practitioner obtains a history, performs a physical examination, and reviews the laboratory tests. Blood tests will be ordered to document the levels of sugar, potassium, sodium, and other electrolytes. Ketone level and kidney function tests along with a blood gas sample (to assess the blood acid level, or pH) are also commonly performed. Other tests may be used to check for conditions that may have triggered the diabetic ketoacidosis, based on the history and physical examination findings. These may include chest X-ray, electrocardiogram (ECG), urine analysis, and possibly a CT scan of the brain. Home care is generally directed toward preventing diabetic ketoacidosis and treating moderately to elevated to high levels of blood sugar. If you have type 1 diabetes, you should monitor your blood sugars as instructed by your health care practitioner. Check these levels more often if you feel ill, if you are fighting an infection, or if you have had a recent illness or injury. Your health care practitioner may recommend treating moderate elevations in blood sugar with additional injections of a short-acting form of insulin. Working with their health care practitioner, people with diabetes should have previously arranged a regimen of extra insulin injections and more frequent blood glucose and urinary ketone monitoring for home treatment as blood sugar levels begin to rise. Be alert for signs of infection and keep yourself well hydrated by drinking sugar free fluids throughout the day. Continue Reading A A A Diabetic Ketoacidosis (cont.) Fluid replacement and insulin administration intravenously (IV) are the primary and most critical initial treatments for diabeti Continue reading >>
