What does a specific gravity of 1.020 mean?
To put it another way, the specific density of water would be 1.000. Ideally, urine specific gravity results will fall between 1.002 and 1.030 if your kidneys are functioning normally. Specific gravity results above 1.010 can indicate mild dehydration. The higher the number, the more dehydrated you may be.
What is normal range of specific gravity of urine?
It measures the ratio of urine density compared with water density and provides information on the kidney's ability to concentrate urine. A urinary specific gravity measurement is a routine part of urinalysis. The reference range is 1.005-1.030.
What is the normal range of PH for urine?
A neutral pH is 7.0. The higher the number, the more basic (alkaline) it is. The lower the number, the more acidic your urine is. The average urine sample tests at about 6.0.
What is the normal PH range of urine?
The glomerular filtrate of blood is usually acidified by the kidneys from a pH of approximately 7.4 to a pH of about 6 in the urine. Depending on the person's acid-base status, the pH of urine may range from 4.5 to 8.
Diagnosis of diabetes insipidus is suspected when a patient reports unusually large and frequent urine output. A urinalysis is done to discover dilute urine (low specific gravity). A water deprivation test may be conducted. Patients with diabetes insipidus continue to produce large amounts of urine despite dehydration.
What can you find out from a urine test?
The urinalysis is a set of screening tests that can detect some common diseases. It may be used to screen for and/or help diagnose conditions such as a urinary tract infections, kidney disorders, liver problems, diabetes or other metabolic conditions, to name a few.
What is specific gravity in a drug test?
The absence of creatinine (<5mg/dl) is indicative of a specimen not consistent with human urine. Specific gravity tests for sample dilution. The normal range for specific gravity is from 1.003 to 1.030. Values outside this range generally indicate specimen dilution or adulteration.
Is there protein in urine?
Healthy kidneys do not allow a significant amount of protein to pass through their filters. But filters damaged by kidney disease may let proteins such as albumin leak from the blood into the urine. Proteinuria can also be a result of overproduction of proteins by the body.
What is the normal range of leukocytes in urine?
If you're healthy, you can still have elevated leukocytes in your bloodstream and urine. A normal range in the bloodstream is between 4,500-11,000 WBCs per microliter. A normal range in the urine is lower than in the blood, and may be from 0-5 WBCs per high power field (wbc/hpf).
How much glucose should be in urine?
The normal amount of glucose in urine is 0 to 0.8 mmol/L (millimoles per liter). A higher measurement could be a sign of a health problem. Diabetes is the most common cause of elevated glucose levels. Your doctor will perform a simple blood test to confirm the diagnosis.
How does a urine dipstick work?
A urine test strip or dipstick test is a basic diagnostic tool used to determine pathological changes in a patient's urine in standard urinalysis. A standard urine test strip may comprise up to 10 different chemical pads or reagents which react (change color) when immersed in, and then removed from, a urine sample.
Which substance should be found in urine?
The biochemicals found in urine are predominately the end-products of the nitrogen metabolism process. These include urea, uric acid, and creatinine. Other components of urine include sodium chloride (common salt), and over 100 other substances that are usually present, but only in trace (i.e. very small) quantities.
What is Pro in a urine test?
A urine protein test is often used to screen for, help evaluate, and monitor kidney function and to help detect and diagnose early kidney damage and/or disease. However, the test can also help screen for several other conditions that can cause proteinuria.
Can you buy urine test strips over the counter?
You can buy over-the-counter UTI dipstick tests at your local drugstore or online. They work much like a pregnancy test: Each kit comes with a testing strip (usually three to a kit). You wet a test strip by holding it in your urine stream for a few seconds.
What does Hypersthenuria mean?
Hypersthenuria is a condition where the osmolality of the urine is elevated. It can be associated with diabetes mellitus and is determined by a urine specific gravity of greater than 1.010.
Obtain the density for the liquid in question. The density of a substance is equal to its mass divided by its volume. You can measure the mass on a scale and record the volume of the liquid used. Use the equation "m / v = D" where m is mass in grams or kilograms, v is volume in milliliters or liters, and D is density.
Leukocyte esterase is a screening test used to detect a substance that suggests there are white blood cells in the urine. This may mean you have a urinary tract infection. If this test is positive, the urine should be examined under a microscope for white blood cells and other signs that point to an infection.
Are urine dipstick tests accurate?
Using a urine dipstick test instead of urinalysis to detect urinary tract infection (UTI) can decrease the time needed to make a diagnosis; however, the diagnostic accuracy of urine dipsticks varies, depending on the standards used. Many experts have recommended urinalysis to confirm urine dipstick test results.
