CD4 stabilization tubes have the ability to ensure internal quality control in the human immunodeficiency virus (HIV) monitoring laboratory by maintaining accurate absolute CD4 T-cell counts for up to 6 days. Here, we assessed this technology for its use in an HIV clinical monitoring laboratory in a resource-poor setting in rural Uganda.
