I recently donated a blood, but I received a letter from the blood center saying that my HBcAb core is positive with Ausab is 26, (but I am tested Negative for
HIV 1+2 Integral ,
HIV 1+2, HBs Ag, HCV, RPR, and HTLV 1+2). They asked me to take 3 dose Hepatitis B vaccine, and they can not accept blood from me again. I am a male 44 years old; I never took the Hepatitis B vaccine before. I am wondering why I am tested positive Hepatitis for B Core Antibody , and what does Ausab 26 mean?
