The cutoff 1st day urine specific gravity in critically ill children: Predictive factor for early abnormal glomerular filtration rate Malaki M - Saudi J Kidney Dis Transplurine concentration testDefinition A urine concentration test measures the ability of the kidneys to conserve or excrete the water appropriately. See also:Alternative Names Water Load Test; Water Deprivation Test How the Test is Performed For this test, the specific gravity of the urine is measured before and after one or more of the following: The test requires a clean urine sample. To get a clean capture sample, men or children should clean the head of the penis. Women or girls need to wash the area between the lips of the vagina with soapy water and rinse well. When you begin to urinate, allow a small amount to fall into the toilet bowl to clean the urethra of pollutants. Then place a clean container under the urine flow and take 1 to 2 ounces of urine. Remove the urine flow container. Cap and mark the container and give it to the healthcare provider or assistant. For babies, wash the area completely around the urethra. Open a urine collection bag (a plastic bag with an adhesive paper at one end), and place it in the baby. For children, the whole penis can be placed in the bag and the adhesive attached to the skin. For girls, the bag is placed on the lips. The diaper as always in the secured bag. This procedure can take a couple of attempts - animated babies can move the bag. The baby should be checked frequently and the bag changed after the baby peed in the bag. The urine is drained in the container for transport to the laboratory. How to Prepare for the Test Eat a normal and balanced diet for several days before the test. Your health care provider will give you instructions for water loading or water deprivation. Your health care provider will instruct you, if necessary, to suspend any medications that may interfere with the test. Medicines that may affect measurements include dextran and sucrose, and a half-ray contrast (die) received within 3 days. How the test will feel The test only involves normal urination, and there is no discomfort. Why the Test is Performed This test is done more often if your doctor suspects that central diabetes is insipid. The test can help to differentiate it from nephrogenic insipid diabetes. This test can also be done if you have signs of SIADH (inappropriate ADH syndrome). Normal values Generally, normal values are as follows: The above examples are common measurements for the results of these tests. Normal value ranges may vary slightly between different laboratories. Some laboratories use different measurements or test different samples. Talk to your doctor about the meaning of the specific results of your test. What abnormal results mean Increase in urine concentration may indicate: The decrease in urine concentration may indicate: Additional conditions in which the test can be performed: References Landry DW, Bazari H.

Urine Specific Gravity Test OverviewA is a painless way for your health care provider to check your health and test the anomalies. One thing your healthcare provider can check in your urine sample test, or urine, is specific gravity. A specific test of urine severity compares urine density to water density. This quick test can help determine how well your urine is diluting. Too concentrated urine could mean that your kidneys don't work properly or that they're not drinking enough water. The urine that is not concentrated enough can mean that it has a rare condition called, which causes thirst and the excretion of large amounts of diluted urine. The main role of your kidneys is to filter your blood and keep normal. Testing the specific severity of the urine is a quick way for your healthcare provider to tell you if your kidneys are trying to make up for any anomaly. Specific gravity tests are useful if your health care provider thinks you have any of the following conditions: You may have to take a specific urine seriousness test several times in a day. This will help your healthcare provider see how well your kidneys are compensating. Before taking a specific urine seriousness test, your healthcare provider may ask you to do some things to prepare for it. First, you will be asked to stop taking any medication that may interfere with the test results, such as those containing the sucrose or dextran. You may have to wait to take the test if you have recently been given an intravenous contrast dye for an MRI or MRI scan. If more than three days have passed since the dye was administered, it should be okay for you to take the urine test. You should also eat a balanced diet in the days before the test. This diet should exclude certain foods that may affect the color of your urine. These include: A sample for a specific urine test contains at least 1 to 2 ounces of urine. The best time to get a sample is the first thing in the morning, when your urine is the most concentrated. Your healthcare provider will give you a cup to collect a urine sample. For the best sample, you should use an antibacterial towel to clean the area around your urethra. This will reduce the likelihood of bacteria contaminating the sample. urinate a small amount, and then place the cup under the urine flow. urinate in the cup until you have a large enough sample, and then end by urinating in the toilet. This is known as the method (or the medium). Your health care provider will send the urine sample to a laboratory while fresh. This will ensure the best results. A laboratory technician will use a refractmeter to project light in the sample and determine its density. This is more reliable than the dipstick method, in which a stick is placed in the urine to measure how much it sinks or floats. While there is evidence at home, the results will not be as accurate as those performed by a professional in a sterile environment. Home testing is more susceptible to contamination. Another benefit to take the test in your health care provider's office is that you can send the sample to the laboratory for more detailed tests and analysis. Sometimes they are used to evaluate how the kidneys dilute and concentrate the urine, being osmolality the index of a concentration. Knowing the osmolality of your urine can help your healthcare provider diagnose certain conditions. To understand urine concentrations, think of the dark color of your urine when you have had nothing to drink at some point. Its urine is lighter and usually has a specific gravity lower when it is well hydrated. The specific gravity of urine is a more accurate measurement of the overall concentration of your urine than looking at the color of your urine alone. Your healthcare provider will examine your urine density relationship with water density. To put it another way, the specific water density would be 1,000. Ideally, the specific gravity results of the urine will fall between 1.002 and 1,030 if your kidneys work normally. Specific gravity results above 1.010 may indicate mild dehydration. The higher the number, the more dehydrated it will be. The specific severity of the urine may indicate that you have additional substances in your urine, such as:Your healthcare provider will use the results of your specific urine seriousness test, along with other urine results, to get a diagnosis. Abnormal specific severity results may indicate: A urine analysis can also measure the concentration of several cells. White blood cells may indicate an infection. And glucose can aim at glucose intolerance or diabetes. Other types of urinalysis include , , and . The results of these tests can help your health care provider perform a more accurate diagnosis. The specific gravity test of the urine involves urinating normally and is not associated with any harmful side effect. However, if you have a urinary tract infection, always notify your healthcare provider if you experience discomfort or any unexpected symptoms. A specific test of urine severity is a painless and easy to take test. Preparation is simple, and it only requires excluding some things from your diet and temporarily stop certain medicines. This test can help healthcare providers with a . When used together with blood test or other urine tests, it can also help healthcare providers identify different conditions. In some cases, the specific gravity test of the urine will show that it is dehydrated or overhydrated. If you are extremely dehydrated and have problems getting enough fluids, you may be given intravenous fluids to help hydrate it faster. Mild dehydration can be resolved by constantly taking more water. If you are overhydrated, your health care provider may perform more tests to look for or , heart, brain or kidney diseases that may be causing.
