I was diagnosed with latent TB last year having to receive 4 months of IV antibiotic. My infectious disease dr told me there’s a small percentage that antibiotic wouldn’t work and I will have to be monitored for life having latent TB. Also, with receiving treatment even if it successfully treated the latent TB it does not mean I will not show positive for latent TB again or have latent TB become active.
I would recommend she get a second opinion from an infectious disease dr who will communicate better to give her a more clear understanding.
Hi, you could start by reading the guidance from the CDC, and WHO. Maybe also Canada and EU.
But I'd be leery that they might be more interested in preventing breakouts, than in her welfare as an individual. Also, the risk of liver damage is probably greater in a 60 yr old than a 30 yr old. I'd venture to say that she shouldn't think about it, before having baseline liver testing.
It would be helpful to know exactly what test was given, and what they were looking for. If she has previously been exposed to or had Tb, she will always test positive for antibodies. That, in itself, is not a concern absent other symptoms.
Regarding medical records, they don't have a choice but to leave it all on her. Unfortunately, there is no database from which the doctors can extract her medical records.
A person can be infected with a different strain of Tb, or re-infection can happen if the first treatment was not successful: https://www.everydayhealth.com/tuberculosis/when-tuberculosis-infection-comes-back.aspx
First step is to find out what test was given, and what the results say.
