Hi Bev. I am glad your hubby will get tested, it is so important.
I recommend IgeneX for Babesiosis, both types of Ehrlichiosis (and/or Anaplasmosis), and Bartonella testing. They do not test for Mycoplasma. I recommend MDL in NJ for Mycoplasma testing.
You can have IgeneX send you a kit. You take it to a doctor who is willing to draw the blood and send it back. The results will be reported to the doctor who sent them in. You can call them at 800-832-3200 for instructions and to get a testing kit.
