Blood test's?

So i went to the doctor today and talked to her about the 4 chemical pregnancy's I've had and she decided that they'll do blood test's for my thyroid, fsh and prolactin levels and if there isn't anything she can do then she'll refer me to a gyne.. So i was curious i guess as to what testing your doctor's did (if they did) after a chemical pregnancy or misscariage?

Thank you and baby dust!
