neutralization tests

tests based on the ability of an antibody to neutralize the biological activity of an antigen. These may utilize antitoxins and toxins or immune serum and viruses or bacteria. The tests are often quantitative whereby antibody (serum) is serially diluted; the reciprocal of the highest dilution of serum neutralizing a standard amount of toxin or virus or bacteria is the neutralizing antibody titer of that serum.
