HIV-Screening

4th-generation HIV screening test detecting both HIV 1/2 antibodies and p24 antigen simultaneously. The dual-detection approach narrows the diagnostic window to approximately 4-6 weeks post-exposure. At EUR 31.71 under GOAe 1.0x rates, no referral needed -- walk in confidentially during collection hours.

The 4th-generation HIV combination test represents the current standard of care for HIV screening across Europe. By simultaneously detecting HIV 1/2 antibodies and the p24 capsid antigen, it identifies infection earlier than older antibody-only assays. The p24 antigen appears in blood approximately 2-3 weeks after infection, during the acute viraemic phase, before the adaptive immune system generates detectable antibodies at 3-6 weeks. This dual approach narrows the diagnostic window period to approximately 4 weeks for most individuals, compared to 6-12 weeks for 3rd-generation antibody-only tests. A negative result at 6 weeks post-exposure is considered conclusive by European Centre for Disease Prevention and Control (ECDC) guidelines. The Robert Koch Institute in Germany follows similar guidance. The test is performed on a standard venous blood sample and requires no fasting or special preparation. A reactive screening result is always followed by confirmatory testing -- typically a Western blot or line immunoassay -- before a definitive diagnosis is made. Mein Direktlabor can arrange confirmatory testing if the screening result is reactive. Germany has approximately 90,000 people living with HIV, with an estimated 8,000-10,000 undiagnosed. Late diagnosis remains a significant public health challenge -- approximately 30% of new HIV diagnoses in Germany are made at an advanced stage when CD4 counts have already fallen below 350 cells per microlitre. The ECDC and Deutsche Aidshilfe both advocate for routine, normalised screening to reduce late diagnosis and improve treatment outcomes. The direct-pay model at Mein Direktlabor offers an alternative to anonymous testing centres (Checkpoints) for individuals who prefer a laboratory setting with rapid result turnaround. The GOAe 1.0x price of EUR 31.71 includes the assay at EUR 20.11, the EUR 4.20 blood draw fee, and the EUR 7.40 outpatient consultation fee.
