Explore the next-generation HIV-1/2 Ab Combo blood rapid testing technology: parameters, manufacturing process, industry insights, and case-driven application analysis.
1. Overview & Industry Trend of HIV-1/2 Ab Combo Rapid Diagnostic Kits
With the global expansion of infectious disease screening, HIV-1/2 Ab Combo rapid test kits are at the forefront of decentralized diagnosis. According to UNAIDS 2023 reports, over 39 million people live with HIV globally, with an annual demand for reliable, high-throughput HIV-1/2 testing exceeding 340 million kits. This surge is fueled by (A) growing community-based screening, (B) fast point-of-care (POC) demand, and (C) regulatory incentives by WHO, CE, and FDA for early detection.
HIV-1/2 Ab Combo kits are engineered to deliver qualitative detection of both HIV-1 and HIV-2 antibodies with high sensitivity and specificity, using whole blood, serum, or plasma. Their deployment spans emergency departments, blood banks, mobile clinics, and large-scale epidemiological networks.

3. Technical Evolution of HIV-1/2 Ab Combo Rapid Test Kits (2015–2024)
Rapid improvements shown in key technical metrics, driven by ISO 13485, FDA EUA, and next-gen antibody designs.
4. Manufacturing Process Flow: How HIV-1/2 Ab Combo Rapid Test Kits Are Made
- Material science: Medical-grade polystyrene (cassette) and nitrocellulose (membrane pads), gold-labeled conjugate pads for high accuracy.
- Core process stages: CNC injection molding → pad impregnation (conjugate, antibody) → laser cutting → robotic assembly → ISO-compliant QC (ANSI/ISO 13485 standard).
- Detection standards: Passes WHO/FDA recommended panel testing; batch testing includes shelf life, humidity, and chemical stability assessment.
- Design lifetime: Shelf stable for 24–30 months at 2–30°C; low degradation as per FDA & EUCMC regulatory shelf-life studies.
Flowchart: Integrated steps from precision molding to bio-chemical membrane strip assembly (exemplified).
