Thyroid level question

You are not a doctor, or if you are a doctor you are not my doctor, it’s not medical advice, blah blah.

My wife is checking back with the doc in a few weeks anyway, but maybe someone here can comment on her Thyroid level results?

Free Thyroxine: .93
TSH Sensitive: 3.86
ABS: < 20
AB: 148

The doc told her not to worry about it for now, but she’s really concerned about the Thyroid Peroxidase AB score of 148. She’s been reading about it online and it says the normal range is 0-35, so this seems WAY off.

The talk about Hashimotos and other auto immune diseases, plus the possibility of infertility has got her spooked.

Anyone know exactly what the number means? And if it really is ok to wait a few weeks for a follow up?
