Transient viremia in HIV-infected patients and use of plasma preparation tubes

Using plasma preparation tubes for the collection and storage of plasma resulted in factitious, low-level human immunodeficiency virus type 1 (HIV-1) viremia among patients receiving highly active antiretroviral therapy who incurred unnecessary additional clinic visits, laboratory testing, and medication changes. We caution clinicians against the routine use of plasma preparation tubes for collection of blood samples for HIV-1 level 1 quantification.
