What Is Titer Testing?
A titer is a laboratory test that measures the presence and amount of antibodies in blood. A titer may be used to prove immunity to disease. It checks for the presence of certain antibodies in the blood stream. Testing involves drawing blood from a patient and check it in a lab for presence of bacteria or disease.The antibody titer is a test that detects the presence and measures the amount of antibodies within a person’s blood. The amount and diversity of antibodies correlates to the strength of the body’s immune response.If the test is positive (above a particular known value) the individual has immunity. If the test is negative (no immunity) or equivocal (not enough immunity) you need to be vaccinated.A Titer Lab Report is generated by the lab that tested the blood sample. The Titer Lab Report must include the test type, exact values, signature, and date. It is often used to see if someone is immune to a certain virus or needs vaccination.
What Do Titer Tests Check For?
Titers check to see if you have had an infection or are immune to a disease. This can happen from having contracted the disease or vaccination. The immune system produces antibodies to mark invading microorganisms for destruction or to neutralize them before they can cause an infection. Invading microorganisms are known as pathogens. Pathogens have markers on them known as antigens, which antibodies find and bind to.It is recommended if you are unsure of your vaccination history, think you may need a booster or have been infected by a disease.One test can check for a variety of diseases including Hepatitis A,Hepatitis B,Hepatitis C,Chickenpox,Rabies,Measles, Mumps or Rubella and Tuberculosis.The binding of antigens to antibodies sparks the immune response. This is a complex interaction of immune tissues and cells that work to defend against invading organisms and fight infection.
Why Is Titer Testing Important?
An antibody titer test is used to determine if you’ve had previous infections and whether or not you need certain immunizations.
Hepatitis B Surface Antibody Immunity, Quantitative - This assay is used to determine immune status for Hepatitis B as =10 mIU/mL as per CDC Guidelines.
RPR (Diagnosis) with Reflex to Titer and Confirmatory Testing - This is a non-treponemal screening test for syphilis. False positive results may occur due to systemic lupus erythematosus, leprosy, brucellosis, atypical pneumonia, typhus, yaws, pinta, or pregnancy. Monitoring of RPR is helpful in assessing effectiveness of therapy.
Varicella-Zoster Virus Antibody (IgG) - Varicella-Zoster Virus (VZV) causes chicken pox and when reactivated, potentially decades later, causes shingles. Twenty percent of adults will develop shingles, a rash or blister of the skin that may cause severe pain. Varicella-Zoster IgG, EIA reliably measures immunity due to previous infection, but is unsuitable for detection of post-vaccination immune status.
Testing titers can help you avoid unnecessary vaccines, save money and remove the hassle of booster shots. It can also help identify any infections or similar problems you may be experiencing.
