Tdap Antibody (Titer) Testing

TDAP ANTIBODY TITER TESTING

Proof of Immunity for Tetanus, Diphtheria & Pertussis

Need proof that you’re protected against tetanus, diphtheria, and whooping cough? A Tdap titer test is a simple blood test that checks your immunity levels.
After vaccination or past exposure, your body creates protective proteins called antibodies. This test measures those antibodies to confirm you have protection against:

Tetanus (Lockjaw) – A serious condition that affects the nervous system

Diphtheria – A potentially life-threatening throat infection

Pertussis (Whooping Cough) – A severe and highly contagious respiratory illness

If your school or employer requires documented proof of immunity, this test provides official lab verification.

Who May Need a Tdap Titer Test?
You may need antibody testing if you are:

Entering a healthcare, nursing, dental, EMS, or medical program

Starting a new job that requires proof of immunization

Enrolling in college or vocational school

Unable to locate your vaccination records

A healthcare worker needing immunity verification

An employer requiring documented compliance for staff

Why Immunity Matters

Tdap protects against three serious bacterial infections that can lead to:

Severe respiratory illness

Nervous system complications

Hospitalization

Life-threatening illness in infants and vulnerable populations

Many institutions now require laboratory confirmation of immunity, not just vaccination records.

Tdap & Pregnancy

Pregnant individuals are advised to receive the Tdap vaccine between 27–36 weeks of pregnancy. This helps transfer protective antibodies to the baby before birth, reducing the risk of whooping cough during the newborn’s most vulnerable months.

Fast. Simple. Reliable.

The Tdap titer test requires only a quick blood draw. Results provide clear documentation you can submit to your school, employer, or credentialing program.
