Determination of tetanus toxoid antibodies is of no value in assessing the need for prophylactic or therapeutic management. Immunity declines with age, and boosters are recommended every 10 years.

This procedure may be considered by Medicare and other carriers as investigational and, therefore, may not be payable as a covered benefit for patients.
