Evaluate the ability of a patient to produce antibody to pure protein vaccines after vaccination to rule out antibody deficiency.
- Patient Preparation
- Serum separator tube. "Pre" and "post" vaccination specimens should be submitted for testing. "Post" specimen should be drawn 30 days after immunization.
- Specimen Preparation
- Separate serum from cells ASAP or within 2 hours of collection. Transfer 1 mL serum to an ARUP Standard Transport Tube. (Min: 0.15 mL) Mark specimens clearly as "Pre-Vaccine" or "Post-Vaccine". If shipped separately, "Post" specimen must be received within 60 days of "Pre" specimen.
- Storage/Transport Temperature
- Unacceptable Conditions
- Plasma or other body fluids.
- After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)
Diphtheria and tetanus:
1. If the post-vaccination concentration is less than 1.0 IU/mL, the patient is considered a nonresponder.
2. If the post-vaccination concentration is greater than or equal to 1.0 IU/mL, a patient with a ratio of less than 1.5 is a nonresponder, a ratio of 1.5 to less than 3.0, is a weak responder, and a ratio of 3.0 or greater, is a good responder.
3. If the pre-vaccination concentration is greater than 1.0 IU/mL, it may be difficult to assess the response based on a ratio alone. A post-vaccination concentration above 2.5 IU in this case is adequate.
