Hi thanks for asking question.... Your friend is HCV positive borderline.. Means his OD optical density value reading by ELISA is near to cutt off range ...Not markedly elevated.... In such case it is better to perform confirmatory test for hepatitis c by molecular method or nucleic acid test (NAT)... If he remain positive usually for more than six month then it could be carrier ..... Clinical follow up necessary... Meanwhile avoid alcohol with drinking more fruit juice ... Take carrot, Indian gooseberry, spinach , lemon juice , apple etc more ... Consult gastroenterologist for your case. You can post your report for further advise . Take care
