A urinalysis is an assortment of tests performed on a urine sample. It is one of the most commonly used methods of medical diagnosis. Some kinds of urinalysis can be done by using urine dipsticks that allow the test results to be read as the color changes. Medical urinalysis usually includes the following: description of the urine sample's color and appearance, its specific gravity, ph value, presence of ketone bodies, proteins, nitrites, urobilinogen, and bilirium.
Urine testing provides useful information to the doctor, assisting in proper diagnosis, monitoring and treatment of a variety of illnesses. Employers also ask for urine tests as part of a pre-employment medical test package. Some urine tests are conducted to determine pregnancy. Urinary tract infections are also detected by way of urine tests. Specific urine tests to determine substance and drug abuse are used by police and rehabilitation programs, and also in professional sports.
Urine testing is a simple procedure that doesn't take too long. It is a non-invasive procedure and involves normal urination in a vial or on a test strip. The urine sample can be collected at home in case of testing for illness or testing for pregnancy. For a drug test, the person has to report at the clinic where the sample is collected and cannot be tampered with. Such a urine test will also test the temperature of the sample, once again to prevent tampering.
An alcohol or drug urine test is conducted to check for the level of alcohol or drug in the system. While some companies claim to sell masking products that can help you pass a urine test, these products are easily detected by the urine test and if detected could land you in trouble. Also, drinking plenty of water or fluids can change the appearance of the urine sample and make it appear pale. This would make the lab technician suspicious of such a sample, and he or she could ask for a fresh sample. T
The best way to pass a urine test for alcohol or drug testing is to avoid these substances altogether or at least some time before the test. Normal results will show no drugs in the urine. However, the use of some medications or foods could cause a false negative, in that case, a gas chromatography mass spectrometry is used to confirm test results.
