How often do I need to take a 'chem-screen' test?

Charles Farthing (Chief of Medicine, AIDS Healthcare Foundation) gives expert video advice on: Why do I need to take lab tests if I have HIV? and more...

If you are not on any treatment, a chem-screen test doesn't need to be done very often, maybe yearly, just as you would in any individual having a routine health screening. But if you're on any antiretroviral therapy, we recommend a chem-screen three or four times a year to check that there's no toxicities from the medication.
