Test Code TTIGS Tetanus Toxoid IgG Antibody, Serum
Useful For
Assessing antibody response to the tetanus toxoid vaccine, which should be performed at least 3 weeks after immunization
Aiding in the evaluation of immunodeficiency
This test should not be used to diagnose tetanus infection.

Specimen Stability Information
Specimen Type | Temperature | Time | Special Container |
---|---|---|---|
Serum | Refrigerated (preferred) | 30 days | |
Frozen | 30 days |
Reference Values
Vaccinated: Positive (≥0.01 IU/mL)
Unvaccinated: Negative (<0.01 IU/mL)
Interpretation
Results greater than or equal to 0.01 suggest a vaccine response.
A tetanus toxoid booster should be strongly considered for patients with anti-tetanus toxoid IgG values between 0.01 and 0.5 IU/mL.
Some cases of tetanus, usually mild, have occasionally been observed in patients with a measurable serum level of 0.01 to 1.0 IU/mL.
