PRE and POST samples should be tested together on the same run to avoid variation in results caused by lot - to - lot and inter-assay variation. It is recommended that two PRE tubes be drawn. Save one PRE serum frozen. The other can be sent to determine the need to vaccinate. If patient already has protective values, there is no need to revaccinate and test a POST sample. If PRE results do not show protective values, send the saved PRE sample together with the POST vaccination sample.
A common method for evaluating suspected antibody deficiency is to immunize the patient with an appropriately selected vaccine, such as Pneumococcal, and determine vaccine-specific antibody concentrations in a serum sample 4-8 weeks post-immunization compared to a pre-immunization sample.
