TB Testing
What is a titer test?
A titer blood test is utilized to ascertain prior infections and the necessity for specific immunizations. This analysis detects and quantifies the antibodies present in an individual's blood.
When should a titer test be conducted?
Certain educational institutions, healthcare facilities, or specific occupations may mandate evidence of vaccination against particular infectious agents. Immunization history can be confirmed through two means:
Vaccination records from healthcare providers: Typically, the primary form of proof is documentation from those who administered the immunization.
When these records are unavailable: A blood titers test can provide the necessary documentation that a school or workplace may require.
What do the results of titer testing determine?
Whether a vaccine has effectively enabled your immune system to safeguard against a specific disease
If an immunization has elicited a sufficiently robust response to provide protection against a specific disease
Whether you have encountered a recent or past infection, such as mononucleosis or hepatitis
Whether you recently experienced or are currently battling an infection
What are the types of immunity?
Active immunity: Developed through prior infection or vaccination, the body's immune system generates antibodies and cellular immunity, typically lasting for years or a lifetime.
Passive immunity: Transferred from sources like mother to infant or through blood products like immune globulin, this type of immunity usually provides temporary protection for weeks to months.
How do I interpret the test results?
Positive titers suggest exposure to a specific pathogen or vaccination for it, indicating adequate immunity to that infectious disease.
Negative titer results signify no immunity to a particular disease, prompting a potential requirement for vaccination by your school or workplace.
