What's a Urinalysis?

There are three ways to test urine, and your test can use all of them.
One way of doing this is by checking the visual color and clarity of the urine. If your urine has blood, it can be red or dark brown. Foam can be a sign of kidney disease, and blurry urine can mean that you have an infection.
A microscopic examination checks for the presence of particles that are too small to be contained in your urine:
- Red blood cells;
- White blood cells;
- Crystals (mineral clots are a possible sign of kidney stones).
The third part of the urine test is a probe that uses a thin plastic strip treated with chemicals. It absorbs into your urine and the chemicals on the stick react and change colour if the level is abnormal. Things that the stylus can check include:
- Acidity or pH. If the acid is abnormal, you may have kidney stones, urinary tract infection (UTI) or other conditions.
- Protein. This may be a sign that your kidneys are not working properly. Kidneys filter out your blood waste.
- Glucose. A high sugar content is a marker of diabetes.
- White blood cells. It is a sign of infection or inflammation, both in the kidneys and elsewhere in the urinary tract.
- Nitrites. This means that there is an infection with certain types of bacteria.
- Bilirubin. If you find this unnecessary product, which is usually removed from the liver, it may mean that your liver is not working properly.
- Blood in your urine. Sometimes it is a sign of infection or certain diseases.
- Urobilinogen. Means that your liver is not working properly.
- Specific weight. Indicator that indicates the level of hydrotation in your body.
- Ketones. This can be a sign that the body is in a state of ketosis, and that there are complications with type 1 diabetes.
