I was tested for MRSA and it came back positive, should I get tsted again after treatment?

No. You are now more likely to have repeat MRSA infections so being seen quickly for infections will help as well as using hibiclens soap for a month. It is not forever....But MRSA can spread in families so a little extra precaution goes a long way. It is not necessary to test after the treatment as the culture said what antibiotic is best.
