My doctor does not want to sign the medical certificate required for Visa O-A.

Any advice or suggestions on getting medical certificate signed without having expensive tests and x-rays? I live in Florida, but I think I read some people did it via tele-health?

I requested the signature from my primary care doctor...but she freaked out saying she can not sign it without running blood tests and x-rays for the "tuberculosis, elephantiasis, leprosy, drug addiction, and third step of syphilis."
