FAQ: Industry Terms and Technical Clarification

Q1: What is the clinical significance of VZV DNA PCR over traditional viral culture?

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. Lyophilized format ensures enzyme and primer stability with negligible activity loss.

Q5: How is "quantitative range" determined in VZV DNA PCR assays?

The quantitative range reflects the interval (copies/mL) within which viral nucleic acid concentration can be precisely measured, directly verified during kit validation across performance lots.

Q6: What is “multiplex capability” and why is it important?

Multiplex capability means detecting multiple viral targets in a single reaction. It saves time, sample material, and can distinguish co-infections – essential for HIV/CMV/VZV panels in immunosuppressed patients.
