In brief: To check immunity

Antibodies are proteins involved in immune reactions.
An antibody titer measures how much of these proteins have been made against a particular substance. For example: to see if you've had recent exposure to an organism like mono; to ensure you are protected against infections like strep; to ensure you have responded to a vaccine; to check for an autoimmune condition; to type blood for transfusion.

Unfortunately, many patients who have received 4 doses of pneumococcal vaccination (PCV-7) before age 2 have not respond well to this vaccine. This is commonly found among persons with recurrent ear or sinus infections. Receiving the more expansive PCV-23 after age 2 typicallty corrects this problem.

In brief: It depends

There are lots of reasons to look at antibody levels, but primarily, it's a measure of how well your immune system is working.
You should discuss this further with the physician who ordered the titer, to get a better handle on what s/he's looking for.
