Serum Iron:-Serum hepatitis B surface antigen (HBsAg) is a reliable biomarker of apparent hepatitis B virus infection. It is secreted as an subviral particles by infected cells in a larger extent than the infectious virons3 and may serve as probable mechanism for evading host immune responses. Total Iron-blinding:- A total iron-binding capacity (TIBC) test measures the bloods ability to attach itself to iron and transport it around the body. A transferrin test is similar. If you have iron deficiency anaemia (a lack of iron in your blood), your iron level will be low but your TIBC will be high. Transferrin Saturation:- Transferrin saturations of less than 20% indicate iron deficiency, while transferrin saturations of more than 50% suggest iron overload. Iron tests frequently performed together to diagnose iron deficiency or overload include serum iron, ferritin, IBC, and transferrin levels.
