Comparative sensitivity of HBV NATs and HBsAg assays for detection of acute HBV infection

Abstract: Newer HBsAg tests would be expected to detect an additional 15 to 21 infected units per 107 donations, compared to licensed HBsAg tests. Sensitivity, WP closure, and yield projections for newer HBsAg assays and pooled-sample NAT are comparable. Single-sample NAT would increase yield by 13 to 15 units per 107 donations over pooled-sample NAT and newer HBsAg assays and by 35 to 50 units per 107 donations over currently licensed HBsAg assays.

“…In the remaining five series of panels, the BLEIA and PCR detected positive samples with the same detection rate. There was little or no difference in the number of days to the first detection of a positive sample between the BLEIA and PCR (0 versus Ϫ1.7 Ϯ 3.0 days), in agreement with the previous study reporting that HBV DNA and HBsAg detections have a good correlation in the early phase of infection (45). Of note, no other HBsAg measurement methods, including the CLIA2 (another commercial CLIA kit), the ECLIA (an electrochemiluminescent immunoassay), or the FEIA1 (a commercial fluorescence enzyme immunoassay kit) were able to detect HBsAg earlier than the BLEIA, and the BLEIA detected HBsAg 5.8 Ϯ 3.7 days earlier than these three HBsAg measurement methods.…”

“…HCV araştırmasın-da kullanılan kitlerin paraproteinemi, üremi, RF pozitifliği gibi durumlarda yalancı pozitifliği de söz konusudur (35) . HCV antijen testi ve NAT kullanımı ile kan güvenliğinin arttırılması sağlanabilir (20,(22)(23)(24)(25)(26)(27)(28)(29)(30)36) . Amerika Birleşik Devletlerinde NAT kullanımı sonrası kan ve bileşenleri ile HCV bulaş riski 1:1,935,000 ünite olarak hesaplanmaktadır (21) .…”

“…NAT sistemlerin etkinliğinin araştırıldığı çok sayıda karşı-laştırmalı çalışma mevcuttur. NAT'ın transfüzyon bulaş riskini azalttığını, ancak sıfırlayamadığını da belirtmek gerekir (20,(22)(23)(24)(25)(26)(27)(28)(29)(30) .…”

“…Bu nedenle HBsAg testlerinin duyarlılığını artırmak amacıyla Chemiluminescence Immunassay (CLIA), HBsAg yoğunlaştırma ve immünkompleks ayrıştırması gibi yöntemler ile ilgili çalışmalar yapılmakta veya uygulanmaktadır [61][62][63]. OHB'nin özellikle transfüzyon ile HBV bulaşına neden olabileceği bilinmektedir ve HBsAg testlerinde yenilikler olsa da HBV belirteci olarak tarama testlerinde HBsAg'nin kullanımında bazı problemler oluşabilir.…”
