In this study well characterized samples of 93 aplastic anaemia patients before blood tranfusion were included. These characteristics include history, physical examination, haematological investigation, bone marrow aspirate and trephine biopsy examination, liver function test (LFTs), renal parameters, viral profile and abdominal ultrasonography. The diagnosis of HA-aplastic anemia was made on the basis of hepatitis (elevated serum aminotransferase enzymes, jaundice, absolute neutrophils counts, platelet counts and reticulocytes. All the 93 samples were checked for serological marker of HAV, HBV, HCV, HDV, HEV, HGV,TTV and B19. One of 93 samples from patients with HA-aplastic anemia has hepatitis G associated aplastic anaemia with positive HGV RNA.
