A urine test, or urinalysis, is a common part of a medical check-up (MCU) package. Because the sample is easy to obtain, this test is one of the simple ways to get a general picture of the body's condition. The results can contain many terms, so understanding the broad outline will make it easier for you to read the results sheet.
What is a urinalysis?
A urinalysis is an examination of a urine sample to look at its various properties and contents. Urine is the product of filtration by the kidneys, so its contents can give general clues about several processes inside the body. This examination usually assesses the physical appearance, the chemical content, as well as the tiny components visible under a microscope.
Things that are usually examined
In general, a urinalysis covers several groups of assessments:
- Physical examination — such as the color and clarity of the urine.
- Chemical examination — assessing the presence of certain substances, for example protein or sugar, as well as the level of acidity.
- Microscopic examination — looking at cells or small particles that may be present in the urine.
Each part provides a different piece of information. A single finding is usually not read on its own, but is combined with the other parts so that the picture is more complete.
Why results can be affected by many things
Urinalysis results can be affected by simple things, such as how much you drink, the food you ate beforehand, physical activity, or the condition of your body when the sample was taken. The way the sample is collected and stored can also have an effect. In addition, the assessment standards can differ between laboratories. For this reason, a result that appears unusual does not necessarily indicate a problem, and is best reviewed by a doctor.
This explanation is meant to help you understand, not to make a diagnosis. If any part of your urine test results confuses or worries you, it is best to discuss it with a doctor, including a 20FIT doctor, who can assess it together with your history and condition.
