When should we do urine analysis?
Your doctor may suggest a urinalysis if you’re experiencing abdominal pain, back pain, frequent or painful urination, blood in your urine, or other urinary problems..
What should not be found in urine?
Normal Results The following are not normally found in urine: Hemoglobin. Nitrites. Red blood cells.
Why do I have white blood cells in my urine?
When this test is positive and/or the WBC count in urine is high, it may indicate that there is inflammation in the urinary tract or kidneys. The most common cause for WBCs in urine (leukocyturia) is a bacterial urinary tract infection (UTI), such as a bladder or kidney infection.
What infections can be found in urine?
The most common infections diagnosed by urinalysis are UTIs, which are one of the most common bacterial infections that require medical intervention. Several other infections such as community-acquired pneumonia and viremia infections can also be diagnosed with the help of urinalysis.
Can drinking too much water cause protein in urine?
Proteinuria found in many people with polyuria. LONDON, Ont. —Drinking two liters of water per day may not benefit most individuals and even could be harmful, investigators say.
What can you not do on a 24 hour urine collection?
DO NOT EAT the following foods for 72 hours prior to and during the collection period: avocados, bananas, butternuts, cantaloupe, dates, eggplant, grapefruit, hickory nuts, honeydew, kiwi fruit, melons, nuts, pecans, pineapple, plantain, plums, tomatoes, walnuts, or substances containing caffeine or nicotine.
How do I read my urine test results?
Normal values are as follows:Color – Yellow (light/pale to dark/deep amber)Clarity/turbidity – Clear or cloudy.pH – 4.5-8.Specific gravity – 1.005-1.025.Glucose – ≤130 mg/d.Ketones – None.Nitrites – Negative.Leukocyte esterase – Negative.More items…•
Why do I have white blood cells in my urine but no infection?
Sterile pyuria. It is possible to have white blood cells in the urine without a bacterial infection. Sterile pyuria refers to the persistent presence of white blood cells in the urine when no bacteria are found to be present by laboratory examination.
What is the most common urine test?
The most common use of urinalysis is to detect substances or cells in the urine that point to different disorders. Urinalysis is used to diagnose disease or to screen for health problems.
Why is an early morning sample of urine used for the test?
First morning specimens are the specimen of choice for urinalysis and microscopic analysis since the urine is generally more concentrated (due to the length of time the urine is allowed to remain in the bladder) and, therefore, contains relatively higher levels of cellular elements and analytes.
How long after collection should urine samples be analyzed?
The guidelines claim that, while urinalysis should be performed as rapidly as possible, analysis can be done up to two hours after sample collection during which time the sample is stored at room temperature (1).
What is the normal range for urinalysis?
According to the American Association for Clinical Chemistry, the average value for urine pH is 6.0, but it can range from 4.5 to 8.0. Urine under 5.0 is acidic, and urine higher than 8.0 is alkaline, or basic. Different laboratories may have different ranges for “normal” pH levels.
Can urine dipstick detect STD?
Sexually Transmitted Infections (STIs) A urinalysis can give clues to the presence of sexually transmitted infections. A positive dipstick for leukocyte esterase or increased numbers of white blood cells in the microscopic exam is suggestive of chlamydia or gonoccocal infection.
When should you read the urinalysis test strip?
The test can often be read in as little as 60 to 120 seconds after dipping, although certain tests require longer. Routine testing of the urine with multiparameter strips is the first step in the diagnosis of a wide range of diseases.
What should you not do before a urine test?
Before your test, make sure to drink plenty of water so you can give an adequate urine sample. However, drinking excessive amounts of water may cause inaccurate results. One or two extra glasses of fluid, which can include juice or milk if your diet allows, is all you need the day of the test.
What are normal results for a 24 hour urine test?
Normal Results The normal range for 24-hour urine volume is 800 to 2,000 milliliters per day (with a normal fluid intake of about 2 liters per day). The examples above are common measurements for results of these tests. Normal value ranges may vary slightly among different laboratories.
What is normal pH of urine?
The normal values range from pH 4.6 to 8.0. The examples above are common measurements for results of these tests.
Why is proper urine collection important?
It’s important to follow the clean catch process to have accurate results from an uncontaminated sample. The most common reason to get a clean catch urine sample is to test for a urinary tract infection (UTI). … However, urine cultures can also check for the following: unusual infections of the bladder or kidney.
