Urine is a direct byproduct of the kidneys, which filter blood and remove waste products. Urine tests can detect many diseases, including some cancers and other infectious and inflammatory diseases. Urine tests are often done to diagnose or monitor diseases of the kidneys, bladder, or urinary tract, including diabetes (diabetes mellitus), kidney disease (nephropathy), bladder infections (cystitis), prostate problems (prostatitis) and infertility problems. A urine test can also be done to look for drugs or medications that may be in your system, such as antibiotics or illegal drugs.
Urine testing is used to detect many diseases, including some cancers and other infectious and inflammatory diseases. Urinary biomarkers are proteins that are released into the urine when the kidneys are damaged by inflammation or injury. These markers can be detected by urine tests, helping doctors diagnose kidney disease or evaluate how well treatment for kidney disease is working.
Urine tests are often done to diagnose or monitor diseases of the kidneys, bladder, or urinary tract. The following conditions may be detected by a urine test:
Diabetes is a condition in which your blood sugar levels are too high. Your body doesn't use insulin properly, or you don't have enough insulin.
A urine test can alert to the presence of diabetes by detecting high blood sugar levels.
If you have kidney disease, your urine will contain excess protein. This indicates that the kidneys are not removing enough waste from your blood. A test called a urinalysis can detect this condition.
Symptoms of Kidney Disease:
How Is Kidney Disease Detected?
Kidney failure can be detected by blood tests, imaging scans of the kidneys and abdomen, and biopsies of tissue from an abnormal area of the kidney. A physical examination is also important because it can identify signs and symptoms such as swelling in the legs due to fluid buildup without having any specific lab tests done beforehand).
Urinary tract cancer is a group of cancers that begin in the parts of the body responsible for making and storing urine. In men, urinary tract cancers most often affect the bladder, prostate, or testicles. In women, they can affect any part of the urinary tract including:
•the ureters (the tubes that move urine from our kidneys to our bladder)
•the urethra (a tube that transports urine from our bladders to outside of our bodies)
•the kidneys (which filter blood and remove waste products)
•the adrenal glands (located above each kidney).
You might have heard that a urine test can only detect drugs in your system for a few days, but this is not true. There are several methods of testing for drugs, and each of them has different time frames. For example, you may be given a blood test to look for drugs in your system at the time of arrest (or just after). This would allow law enforcement to determine if you were impaired with alcohol or marijuana right before driving.
If you are being tested as part of probation conditions or if you are trying to get into college or graduate school, they may give you an oral swab test which detects the presence of cocaine and amphetamines in the saliva. This kind of test can be done up to 3 days after use.
Another type of drug screening method involves collecting sweat from your skin through patches applied directly on top or underneath layers like clothing (this is called passive sampling). These patches then collect sweat over 24 hours and send it off for analysis!
A midstream urine sample is one that you collect yourself, by simply urinating into a container. A clean-catch urine sample is an example of a midstream urine sample.
It's important to know whether you need to collect a "clean-catch" (midstream) urine sample or a catheterized urine sample. A catheterized urine sample must be provided through the use of a tube inserted into your bladder (urinary tract). This type of collection method may not be possible for some people who have certain medical conditions or physical limitations, so it's best to consult with your doctor before making any decisions about how and when he or she would like you to provide specimens for drug testing purposes.
Urine tests are a common and important part of medical care. They can help diagnose and monitor many illnesses, including some cancers and other infectious diseases. It is important to learn whether you need to collect a "clean-catch" (midstream) urine sample or a catheterized urine sample.
