Precision of Alloantibody Titration in Gel vs. Tubes - AABB

This study compared gel titration and tube titration for precision as an indicator of which method can more accurately indicate that a true rise in titer has occurred.

Antibody Titer Test Definition The antibody titer is a test that detects the presence and measures the amount of antibodies within a person’s blood. The amount and diversity of antibodies correlates to the strength of the body’s immune response. The antibody titer is a measurement of how much antibody an organism has
