Amaç: Hepatit C virüsü (HCV) kor antijen testinin tanı değerinin antiHCV testi pozitif veya negatif olan hastalarda HCV ribonükleik asit (RNA) ile kıyaslanarak araştırılmasıdır.Gereç ve Yöntemler: Necmettin Erbakan Üniversitesi Üniversitesi Meram Tıp Fakültesi'ne Aralık 2010- Şubat 2012 tarihleri arasında başvuran ve çeşitli nedenlerle HCV RNA testi çalışılan 189 hastadan elde edilen serum örnekleri bu çalışmaya dahil edildi. İki mL serum örneği uygun koşullar altında saklandı ve anti HCV, HCV kor antijen ve strip immünblot testi [Ticari INNO LIA(TM) HCV Score testi (Innogenetics NV in Ghent, Belçika)] testleri çalışıldı. HCV RNA pozitif olan örneklere genotipleme yapıldıBulgular: Çalışmamızda HCV kor antijen testinin sensitivite, spesifite; negatif prediktif değer ve pozitif prediktif değerleri sırayla %96,2, %100, %97,3 ve %100 olarak tespit edildi. Genotipleme yapılan 65 örneğin 59'u genotip 1b, 2'si genotip 1a/1b, 1'i genotip 3a, 1'i genotip 4, 1'i genotip 2a/2c ve 1'i genotip 1a olarak tespit edildi.Sonuç: HCV kor antijen testi sensitivitesi ve spesifitesi yüksek, kolay uygulanabilir, güvenilir bir testtir. Bu test HCV enfeksiyonunun tanısında anti-HCV test sonuçlarının konfirmasyon ve tamamlayıcı testi olarak kullanılabilir.
Objective: It was aimed to investigate diagnostic value of hepatitis C virus (HCV) core antigen test in patients with positive or negative anti-HCV assay by comparing with HCV ribonucleic acid (RNA) assay.Materials and Methods: Serum samples obtained from 189 patients who were admitted to Necmettin Erbakan University Meram Faculty of Medicine between December 2010 and February 2012, and HCV RNA assay were carried out for various reasons. Two mL of samples were stored under suitable conditions and antiHCV, HCV core antigen and strip immunoblot assay [Commercial INNO LIA(TM) HCV Score (Innogenetics NV in Ghent, Belgium)] were performed. Genotyping was performed in the amplicons of the samples with positive HCV RNA test.Results: The diagnostic sensitivity specificity, negative predictive value and positive predictive value of HCV core antigen test were 96.2%, 100%, 97.3%, and 100%, respectively. Sixty-five serum samples were genotyped and their distribution were detected: Fiftynine samples were genotype 1b, 2-genotype 1a/1b, 1-genotype 3a, 1-genotype 4, 1-genotype 2a/2c, and 1 was genotype 1a.Conclusion: It was concluded that HCV core antigen assay is highly specific, sensitive, reliable, reproducible, and easy to perform. It may be applied as a supplemental and confirmatory test in anti-HCV assays in the diagnosis of HCV.
