VZV DNA PCR offers rapid results (2 hours vs ≥72 hours for viral cultures), higher sensitivity (LOD ≤ 50 copies/mL), and can differentiate vaccine vs wild-type strains via sequence analysis. Viral culture often fails for latent or low-titer specimens. Q2: What manufacturing standards should a PCR kit comply with? Key standards include ISO 13485:2016 (medical device QA), FDA 21 CFR Part 820 (USA), and CE-IVD marking (EU). Compliance ensures traceability, batch consistency, and clinical safety. Q3: What are the main materials used for PCR plasticware? High-clarity polypropylene is selected for PCR tubes/plates due to low DNA adsorption and thermal resilience, in line with ISO 10993 for medical compatibility. Q4: What is the shelf life and storage condition for Cowingene detection kits? The Cowingene Borrelia Burgdorferi Detection Kit has a shelf life of up to 24 months at 2-8°C.
