Chem-Screen (CS) Test
en español

Have you ever wondered why your doctor, nurse, or lab technician takes so many tubes of blood? Some blood samples are used to measure your viral load, CD4 cells, and other blood cell counts. At the same time, some samples are used to perform a blood chemistry test on a regular basis to monitor other important components of your health.

The blood chemistry test—also known as a chem screen—measures a number of important chemicals produced by your body to help it function properly. While a chem screen won't really tell you much about HIV or how your immune system is doing, it can help you and your doctor determine if another infection is present in the body or if you're having any side effects to the drugs you're taking.

A chem screen can involve many different tests, but usually measure between 6 to 24 chemicals. Some of the most important chemical levels in people living with HIV can be seen in the following example of a chem screen lab report. Click on a test name in the left column to view an explanation of its significance & meaning. (note: to see and/or print a complete list of test name explanations, click here.)
