Summary
This study adapted polymerase chain reaction (PCR) to screen 3,000 blood donations daily for HBV, HCV, and HIV-1, detecting infections missed by serological tests. This method significantly reduces diagnostic window periods, enhancing blood transfusion safety.
Area of Science:
- Virology
- Molecular Biology
- Public Health
Context:
- Blood donation screening is critical for preventing transfusion-transmitted infections.
- Traditional serological tests have limitations, including a diagnostic window period.
- High-throughput screening methods are needed to ensure blood supply safety.
Purpose:
- To adapt and validate a polymerase chain reaction (PCR) method for high-volume screening of blood donations.
- To detect Hepatitis B Virus (HBV), Hepatitis C Virus (HCV), and Human Immunodeficiency Virus type 1 (HIV-1) contamination.
- To assess the sensitivity, efficiency, and cost-effectiveness of the adapted PCR method for blood screening.
Summary:
- An automated PCR method was developed to screen up to 3,000 blood donations daily for HBV, HCV, and HIV-1.
- The method involves pooling samples and uses a multi-step PCR process with sensitive detection.
- Sensitivity ranged from 1,000-1,500 genome equivalents/ml for HBV/HIV-1 and 2,000-2,500 for HCV, comparable to commercial kits for non-pooled samples.
- Validation included rigorous controls and testing against national and international standards.
- Routine application screened 327,013 donations, identifying 16 previously undetected viremic donations.
Impact:
- The adapted PCR method significantly shortens the diagnostic window period for transfusion-transmitted viral infections.
- It identified multiple infectious donations that would have passed serological screening, preventing potential transmissions.
- The method offers a cost-effective solution (15 DM per donation) for large transfusion centers, enhancing overall blood safety.
- This validated PCR approach represents a new standard for preventing HBV, HCV, and HIV-1 transmission through blood transfusions.
