Summary Introduction
Introduction:
To diagnose a disease the serum (blood fluid without the clotting factors and blood cells) or plasma (serum with clotting factors) samples are tested to detect antibodies in the samples are checked for the presence of a particular antibody so as to find the extent and type of infection. For this detection, various techniques are used such as ELISA (enzyme-linked immunosorbent assay), fluorescent antibody (FA) test, fluorescent-activated cell sorter (FACS), and western blotting.
