Hello. Thank you for coming to JustAnswer with your question, and welcome.
Do you know how many times your daughter has received the skin test?
Why are is the facility doing monthly skin tests? Is this just normal procedure, or is there a risk due to exposure to someone who has had TB?
She has been there for 12 months so I am assuming 12. This is normal procdure at the facility.
Does she have any symptoms of illness, or has she been exposed to someone who is ill and coughing?
There are a few reasons for a "false positive' result on the skin test:
---having received an immunization for TB, called "BCG" (this is not usually done is the U.S., but is done in other countries)
---currently has (or had in the past) a Mycobacterial infection, that is not actually TB
---had a previous infection with TB, but does not have a current active infection
---the skin test was improperly administered
There, of course, is the possibility that she has been exposed to TB. The facility most likely has procedures for following up by doing some more testing (usually an exam by a physician, and a chest xray or CT scan) to determine if she has been infected with TB. Until this is done, you will not really know.
The facility "community" is at high risk, otherwise they would not do testing so frequently. So, I would advise that a visit by her baby daughter be put on hold until your daughter knows what is going on.
If it turns out that she has a TB infection, there is treatment for it.
