I'm getting mmr, varicella, & hep c titers for school. will these be affected by any of the following: amoxicillin, prednisone, or loestrin fe 1/20?

Prednisone: This med can decrease antibody production if taken in high enough doses.Please clarify that with your treating doc. It could alter your test results.The others won't.

Agree with first ans: Although chronic high dose systemic corticosteroids can lower antibody levels (as correctly suggested by Dr. Ferguson), it is highly unlikely that a normal dose of prednisone would lower your levels to an undetectable level. However, if your titers come back with unexpected results, talk to your doctor.
