Frequency of hepatitis C viral Rna in anti-hepatitis C virus non-reactive blood donors with normal alanine aminotransferase.
J Coll Physicians Surg Pak Jan ;20(10):662-4.

Objective: To determine the frequency of HCV RNA in an anti-HCV non-reactive blood donor population with normal ALT, and its cost effectiveness. Study Design: An observational study. Place and Duration of Study: Baqai Institute of Haematology, Baqai Medical University, Karachi, and Combined Military Hospital, Malir Cantt, Karachi, from May 2006 to April 2008. Methodology: After initial interview and mini-medical examination, demographic data of blood donors was recorded, and anti-HCV, HBsAg and HIV were screened by third generation ELISA. Those reactive to anti-HCV, HbsAg and/or HIV were excluded. Four hundred consecutive donors with ALT within the reference range of 15-41 units/L were included in study. HCV RNA RT-PCR was performed on 5 sample mini-pools using Bio-Rad Real time PCR equipment. Results: All 400 donors were male, with mean age 27 years SD + 6.2. ALT of blood donors varied between 15-41 U/L with mean of 31.5+6.4 U/L, HCV RNA was detected in 2/400 (0.5%) blood donors. Screening one blood bag for HCV RNA costs Rs 4,000.00 equivalent to 50 US dollars, while screening through 5 sample mini-pools was Rs. 800.00 equivalent to approximately 10 US dollars. Conclusion: HCV RNA frequency was 0.5% (2/400) in the studied anti-HCV non-reactive normal ALT blood donors. Screening through mini-pools is more cost-effective.
