K.A.
The dr is right if the boil has dried up then there is not anything to sent to the lab...But on the upside ( this is just my opinion and I have never had any of the 6 in my family that carries staph have MRSA) But if it was MRSA the meds would not have cleared it up that easly. MRSA is highly resistant to meds and it would have taken alot more meds then it sounds like she has taken. I hope this helps, like I said before have her use the hibiclen and you could even buy some for your children to use after she leaves her house if that makes you sleep better at night. Although that is not needed. Hope this helps.
