The accuracy of a viral load test is greatest if some simple guidelines are followed:
- Different viral load tests may report slightly different results. It is important to have blood tested at the same clinic, using the same testing method. - Follow the physician�s treatment guidelines carefully. Not following treatment guidelines can lead to an increase in viral load, and possibly allow the HIV-1 virus to become resistant to the drugs being taken. - Notify the physician if another kind of infection (like a cold) arises or vaccinations have recently been given. Vaccinations or infections might lead to a momentary increase in viral load.
