Titer Testing

Posted on August 9, 2018 at 12:08 PM by Doug Bolnick



Many preventable diseases managed through childhood vaccination efforts have resurfaced in recent years as individual immunity levels have decreased over time. Outbreaks of measles, mumps and chickenpox have spread in schools, universities and communities across the nation. To help individuals know if they are immune or need a booster for these vaccine preventable diseases, the Health Services Clinic offers titer screenings.

Why Do We Need Titer Tests?

These routine tests measure antibodies in the blood to determine a person’s level of immunity to specific diseases. Titer screenings help determine if any booster vaccinations are necessary to further protect against preventable illness. These tests also provide proof of immunity for those who may have lost their vaccination record or wish to avoid unnecessary vaccinations. Those who may require a titer test include individuals:
  • Studying in a health-related educational discipline, especially those entering nursing or medical schools.
  • Attending universities or colleges that require proof of immunity.
  • Who require proof of immunity for employment, especially those in the healthcare field.
  • Who may be traveling to foreign countries or who will be around newborn babies.

What Should I Expect During the Screening?

Titer screenings involve the collection of a small amount of blood, which is tested for specific antibodies. After the blood draw, test results typically are received within three days. Individuals can obtain their own results from our system or Health Services’ staff will contact individuals if boosters are recommended. Those vaccinations can be obtained through the division’s Immunization Clinic. To schedule an appointment through the Immunization Clinic, please call 636-949-1857.
