* Collection Instructions *

If you are interested in PRE and POST vaccination testing, please follow these instructions:

• 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.

Ambient: 7 days

Refrigerated: 14 days
