Antibody titer

Alternative names:

serum antibodies; titer - antibodies

Normal values:

This depends of the antibody being tested. If your health care provider is testing for antibodies against your own tissue, then the normal value would be zero.

If your health care provider is testing to see if your immunization brought your antibody titer up to a preventative level, then that would be a given value determined by that immunization.

What abnormal results mean:

If your health care provider is testing for antibodies against your own tissue, abnormal results would show a positive antibody titer. This means that your immune system is fighting its own tissue, cells, or substances.

If your health care provider is testing to see if your immunization brought your antibody titer up to a preventative level, an abnormal result would indicate that your body has not mounted an adequate response against the immunization, and you are not protected from the disease in its pure infectious form.
