CD4 Results with a Bias Larger than Hundred Cells Per Microliter Can Have a Significant Impact on the Clinical Decision During Treatment Initiation of HIV Patients

摘要

Background: CD4 counts are currently used to assess HIV patients for treatment eligibility and to monitor antiretroviral response to treatment. The emerging point-of-care devices could fill an important gap in resource-limited settings. However, the accuracy of CD4-counting instruments is diverse and data on how CD4 measurement errors have an impact on clinical decisions are lacking.
