In den vergangenen zwei Jahren gab es drei wichtige neue Aspekte bezüglich Diagnostik einer HIV-Infektion: Das diagnostische Fenster bei den HIV Tests der 4. Generation wurde von 12 auf 6 Wochen herabgesetzt. Das diagnostische Fenster bei HIV Tests der 3. Generation bleibt weiterhin bei 12 Wochen (1) Die Publikumsabgabe von HIV-Selbsttests wurde bewilligt (auch als Heimtest bezeichnet). (2) HIV-PCR und insbesondere der GeneXpert Xpert ® HIV-1 Viral Load Test soll besonnen eingesetzt werden.   Was bedeutet dies nun für die praktische Arbeit?
