Tetanus Antitoxoid Test
The tetanus antitoxoid test measures the level of antibodies against tetanus in a blood sample. Quest describes it as a way to evaluate antibody response following immunization with Tetanus Antitoxoid.
About this test
Tetanus antitoxoid antibody reflects the immune system's response to tetanus vaccination. Quest lists this test under names including Tetanus Toxin Antibody and Tetanus Toxoid Antibody, and it is analyzed using an immunoassay method on a serum sample.
Quest notes that tetanus, caused by the bacterium Clostridium tetani, can still occur in some individuals even when their antibody levels would otherwise be considered protective, and that results should not be used to determine whether antitoxin administration is clinically necessary. Because of that, a clinician reads the result in the context of the person's vaccination history and clinical situation rather than as a stand-alone answer.

Frequently asked questions
What does the tetanus antitoxoid test measure?
It measures the level of antibodies against tetanus in a serum sample, using an immunoassay method. Quest describes this as a way to evaluate the antibody response following Tetanus Antitoxoid immunization.
How is the sample collected?
The test uses a 1 mL serum sample from a routine blood draw at a Quest Diagnostics patient service center.
Do I need to prepare for this test?
No preparation instructions are listed for this test, though people follow any instructions their ordering clinician provides.
Does a protective antibody level mean tetanus can't happen?
No. Quest notes that tetanus, caused by Clostridium tetani, can still occur in some individuals even with antibody levels that would otherwise be considered protective.
Can this result tell a clinician whether antitoxin treatment is needed?
No. Quest states that results should not be used to determine whether antitoxin administration is clinically necessary; that decision is made by the clinician based on the broader clinical picture.
How much is a Tetanus Antitoxoid test?
