Urine Testing Stix

Urine Testing Stix

Human and animal diabetics both use ketostix or ketodiastix. These are reagent indicator strips that test urine for only ketone (ketostix) or for both ketones and glucose (ketodiastix). These stix are available at any brick-and-mortar or Internet pharmacy that sells human diabetic supplies. Stix do expire, so check the unopened expiration date when you buy them and record the date you open them. Keep the bottle tightly closed when not in use; prolonged exposure to air can produce false negative urine ketone test result.s [1] Wal-Mart and Sam's Club sell a ReliOn branded urine ketone test strip made by Bayer, the maker of Ketostix. [2][3] If the foil-wrapped Ketostix, rather than the ones in vials are purchased, you may find it less wasteful. After the bottle is opened, the remaining unused strips have only a 6 months' life. By using the foil-wrapped ones, you can extend the "life" of your purchase. The singly-wrapped ones can have a unopened expiration date of up to two years. You are then only using what you need when you need it, having the rest still sealed and potent until the indicated expiration date. [4] You should test your pet's urine for ketones for the reasons discussed at ketones. You may test your pet's urine for glucose because you've been instructed to do so by the vet as a method of gauging regulation or your pet is undiagnosed and you want to determine whether there is hyperglycemia. Some reasons for preferring testing glucose levels by using blood over urine testing is that the urine used in testing may have been in the bladder for hours. Because of this, it may not be a reliable indicator of what systemic glucose levels are at the time of testing. [5] What's seen when testing urine for glucose is an average of what the level of glucose has been over a Continue reading >>

Diabetic Testing

Diabetic Testing

Diabetic Testing - Knowledge is Power! Regular diabetic testing is essential for proper management of diabetes. Depending on the severity of the diabetes, a diabetic may be instructed to test their blood sugar levels as often as every two hours. Most of the medical complications associated with diabetes are caused by the long-term effects of high blood glucose, and low blood glucose must me controlled as well. Diabetic testing equipment is available from most medical supply stores and pharmacies. There are many options available. The oldest technique still in use involves blood glucose testing strips that are compared against a color chart like ph testing paper. There are also many glucose monitors available that will electronically read glucose levels off their own type of testing strips. All of these diabetic testing techniques require collecting blood for the test, most often by pricking the fingertip with a special lancet, and squeezing a drop of blood out of the finger. The finger is then pressed against the diabetic testing strip, allowing measurement of blood glucose either with an electronic blood glucose meter or testing strip color chart. Many electronic diabetic testing glucose monitors are available with speech adapters, allowing diabetics with vision problems to hear their blood glucose test results. Another (recently FDA approved) glucose monitor reads blood glucose levels through the skin every 20 minutes, and only needs to be calibrated twice a day with a finger prick blood sample. For diabetics who are unable to obtain a large enough blood sample with a regular finger lancet, special lancets with integrated pump devices can be used to collect blood samples from other locations. There is a lot of current research into 'non-invasive' diabetic testing equi Continue reading >>

Color Spectrophotometers Are Essential For Creating Accurate Medical Test Strips

Color Spectrophotometers Are Essential For Creating Accurate Medical Test Strips Color Spectrophotometers Are Essential For Creating Accurate Medical Test Strips Medical test strips provide users with important information about their health. Image Source: Shutterstock user memorisz Medical test strips must be as accurate as possible to be effective, as even subtle color inconsistencies between the strip and the color-coded test package could have negative consequences for the person using the strip. For example, if someone who has diabetes uses a urinalysis test strip to monitor the condition, a disagreement between the strips color and the diagnosis code could lead to an inaccurate assessment of blood glucose levels, potentially compromising patient health. For this reason, medical test strip manufacturers need to have a reliable color quality control protocol in place when they create their products. Spectrophotometric instruments allow manufacturers to ensure that their test strips and diagnosis codes match as perfectly as possible, making it easy for customers to see where they fall on the color scale. Why Color Accuracy Matters in Medical Test Strips While many healthcare professionals use medical test strips to diagnose conditions in patients, self-administered over-the-counter medical test strips are becoming more popular. In fact, at-home test strip sales increased by more than 45 percent between 2010 and 2012. 1 The blood glucose test strip market, in particular, is consistently growing in value and is expected to be worth nearly $13 billion worldwide by 2021. 2 However, despite the popularity of at-home test strips, there are still some risks associated with using test strips at home. In a medical office, doctors have more tools at their disposal to diagnose Continue reading >>

Home Urinalysis Test Strip Color Chart and Explanations Synopsis : Example color chart to compare home urine test strip colors in comparison to a urinalysis color chart of what each ideal test result color should read. The elimination of urine is very important for different bodily functions. It regulates the balance of water in the body, for example, and also gets rid of substances that are produced during metabolic processes and are no longer needed by the body. Your urine can tell a lot about your current health, some of these tests are described below. What is a Dipstick or Test Strip Urinalysis? A urinalysis is a urine test best performed on a full bladder first thing in the morning. A urinalysis checks appearance, concentration and content of urine and is used to detect and/or manage a wide range of medical disorders, such as urinary tract infections (UTI's), kidney disease and diabetes. A dipstick, usually a thin, plastic stick with strips of chemicals on it, is coated with urine, the chemical strips will change color if certain substances are present or if certain levels are above, or below, normal which can indicate the presence of compounds like proteins, ketones, hemoglobin, and nitrites, as well as harmful pathogens. Dipstick urinalysis is convenient, but false-positive and false-negative results can occur. No preparation other than cleansing the area around the urethra (urinary opening) is required for the automated dipstick urinalysis. IMPORTANT NOTE: The test strips are available without a prescription at your local pharmacy or online stores such as Amazon on the Internet. Home use urine test strips are NOT intended for self-diagnosis purposes, and should be used in consultation with your doctor. It is always preferable to consult a medical practitioner Continue reading >>

Understanding Gestational Diabetes: Glucose Monitoring

Understanding Gestational Diabetes: Glucose Monitoring

Fetal Monitoring, Gestational Diabetes, Integrative Medicine, Pregnancy and Birth, Weight Management What is self blood glucose monitoring? Once you are diagnosed as having gestational diabetes, you and your health care providers will want to know more about your day-to-day blood sugar levels. It is important to know how your exercise habits and eating patterns affect your blood sugars. Also, as your pregnancy progresses, the placenta will release more of the hormones that work against insulin. Testing your blood sugar level at important times during the day will help determine if proper diet and weight gain have kept blood sugar levels normal or if extra insulin is needed to help keep the fetus protected. Self blood glucose monitoring is done by using a special device to obtain a drop of your blood and test it for your blood sugar level. Your doctor or other health care provider will explain the procedure to you. Make sure that you are shown how to do the testing before attempting it on your own. Some items you may use to monitor your blood sugar levels are: Lancet–a disposable, sharp needle-like sticker for pricking the finger to obtain a drop of blood. Lancet device–a springloaded finger sticking device. Test strip–a chemically treated strip to which a drop of blood is applied. Color chart–a chart used to compare against the color on the test strip for blood sugar level. Glucose meter–a device which “reads” the test strip and gives you a digital number value. Your health care provider can advise you where to obtain the self-monitoring equipment in your area. You may want to inquire if any places rent or loan glucose meters, since it is likely you won't be needing it after your baby is born. How often and when should I test? You may need to test your blo Continue reading >>

Glucose Test Strips | Diabetic Test Strips | Total Diabetes Supply

When test strips were first introduced in the early 1980s, the process was difficult for most people. It was hard to operate and it needed a lot of blood. An enzyme used in the early test strips convert the glucose in the drop of blood into dye; the glucose meter shines a beam of light to the strip and detects how much light was absorbed by the dye. The advent of electrochemistry in the 90s made test strips what they are today. Instead of dyes, the glucose is converted into electrical current. The meter measures glucose concentration through these electric currents. At least 0.5 l to 1 l of blood is needed per reading. It can detect 0 3000 mg/dL or 0-3%. Measurements are just approximations and may vary for every manufacturer. Reapplication of blood on the same strip may be necessary for some test strips to work properly. The quality of glucose strips is an important factor in glucose testing. Better strips mean better readings. Other factors that may affect glucose reading include: Instability of enzymes when enzymes are expose to humidity and extreme temperatures, the activity of the enzyme decreases, and so is its accuracy. Glucose strip manufacturers have tried fixing this problem by administering chemicals to stabilize the enzymes. Strip circuit issues test strips contain maze-like wire that connects the part with blood sample to the end part inserted into the meter. Small errors in the circuit, such as varying thickness of metal, may alter the current and provide inaccurate readings. Other blood components enzymes may get confused by other sugar components of the blood such as maltose. Makers of test strips often used enzymes that only test for glucose and ignore other sugar types. Active ingredients in certain medications may also affect meter readings.

How To Read The Results Of Blood Glucose Test Strips

How To Read The Results Of Blood Glucose Test Strips

1 Review the digital screen on the test meter after you’ve added a drop of blood to the test strip. After analyzing the blood, the meter will automatically display the blood glucose result -- it's as simple as that. 2 Compare the displayed number with your blood sugar guidelines. The American Diabetes Association recommends that a person’s blood sugar ranges from 70 to 130 before a meal or less than 180 after a meal. However, your doctor might provide a more individualized range based on your lifestyle and health status. 3 Consult your instruction manual if an error displays on the screen. Error codes and symbols differ from one meter to the next. You might see an error if you improperly inserted the test strips or dropped too much or too little blood onto the test strip.

Urinalysis Test for the Detection of Glucose in Urine: Urine test strips are used to monitor urine specimens for various biochemicals and their connection to certain diseases. All urine test strips yield clear and acccurate results in less than 30 seconds. Results can be interpreted using visual comparison of the reagent pads to the color chart or other compatible automated Urinalysis equipment or with a Uritek Strip Reader. Collect a fresh urine sample in a clean, dry container preferably glass. First morning samples contain the highest concentration of target markers. Remove one reagent strip from the bottle and immediately replace the container cap, minimizing the exposure of the remaining test strips to light and air. Completely immerse the reagent pads of the strip in the urine sample and then remove immediately to avoid dissolving out the reagent pads. While removing the reagent strip, run the edge of the strip against the rim of the specimen container to remove excess urine. Hold the strip in a horizontal position to prevent possible cross contamination of chemicals located in adjacent reagent pads. Compare the color change of reagent pads to the corresponding color chart on the bottle label. Read results according to the chart's time frame for each panel tested. Record the results of your readings for discussion and/or evaluation with your physician or healthcare provider and then discard the used reagent strip. Each vial of urinalysis reagent strips includes a color coded chart. The reactive color of each panel on the test strip is compared to the closest corresponding color on the result chart. The concentration level range for each chemical marker is indicated below each color block on the result chart. As with all tests dealing with color intensity or color Continue reading >>

Urine Tests For Diabetes: Glucose Levels And Ketones

Urine Tests For Diabetes: Glucose Levels And Ketones

What Are Urine Tests for Diabetes? Diabetes is a condition that is characterized by high blood sugar levels. This is due to the body’s inability to make any or enough insulin, use insulin effectively, or both. Insulin is a hormone that helps the cells of your body absorb blood sugar to make energy. Insulin is produced by the pancreas after you eat food. There are two major classifications of diabetes: Type 1 diabetes occurs when the body’s immune system attacks and destroys insulin-producing cells in the pancreas. This type is usually diagnosed in childhood and develops quickly. Symptoms include quick weight loss, excessive thirst, excessive urination, and fatigue. Type 1 makes up just 5 percent of diabetes cases in the United States. Type 2 diabetes is when cells aren’t able to use insulin effectively anymore. This is called insulin resistance. If the cells can’t take in and store glucose, the glucose remains in the blood. Eventually the pancreas is unable to produce enough insulin to keep blood sugar levels within normal ranges, and diabetes develops. This type of diabetes develops gradually and is associated with being overweight and having a sedentary lifestyle. Diabetes causes blood glucose (blood sugar) to rise to abnormally high levels. In type 1 diabetes, the body may also begin to burn fat for energy because the cells aren’t getting the glucose they need. When this happens, the body produces chemicals called ketones. When ketones build up in the blood, they make the blood more acidic. A buildup of ketones can poison the body and result in coma or even death. Urine tests aren’t ever used to diagnose diabetes, but they may be used to monitor a person’s levels of urine ketones and urine glucose and sometimes to make sure their diabetes is being manag Continue reading >>
