Performance evaluation of the Pima™ point-of-care CD4 analyser using capillary blood sampling in field tests in South Africa.

Background: Point-of-care CD4 testing can provide immediate CD4 reporting at HIV-testing sites. This study evaluated performance of capillary blood sampling using the point-of-care Pima™ CD4 device in representative primary health care clinics doing HIV testing.

Methods: Prior to testing, prescribed capillary-sampling and instrument training was undertaken by suppliers across all sites.

Providing immediate CD4 count results at HIV testing improves ART initiation.

Background: In South Africa, CD4 count results are typically available within a week of testing. However, 35%-55% of newly diagnosed HIV-positive patients do not return for their CD4 results and therefore, do not access further care. We evaluated the impact of a CD4 count result and patient written information provided immediately after diagnosis on retention in care.
