A titer is a laboratory test that measures the amount of antibodies present in a person’s blood. It can be used to determine if a person has had any previous infections, and whether there is a current immunity. Certain employers and guidelines require candidates and employees to undergo titer testing as part of their vaccination policies.

A varicella antibody test measures the levels of varicella (chickenpox) antibodies present in a person’s blood. A positive result typically indicates immunity due to prior exposure or previous vaccination.
