The primary purpose of routine laboratory testing in HIV care is to monitor viral load and CD4 counts. This practice is essential because it allows healthcare providers to evaluate the effectiveness of antiretroviral therapy (ART) and the overall immune status of the patient.

Viral load testing measures the amount of HIV in the blood. Lowering the viral load to an undetectable level is a key goal of HIV treatment, as it helps reduce the risk of disease progression and transmission. CD4 counts indicate the strength of the patient's immune system; higher CD4 counts signify a healthier immune response, while lower counts suggest a weakened immune system that is more susceptible to opportunistic infections.

Monitoring these two parameters helps in making informed decisions regarding treatment adjustments, maintaining adherence to therapy, and assessing the patient's prognosis. Both viral load and CD4 count are closely associated with the clinical management of HIV and are vital for achieving optimal health outcomes for individuals living with this condition.
