James, have you asked the doctor's office to notify you of any cancellations? This may get you in sooner. Or you could try another doctor to see if you can get in sooner.
You can order the test kit from IgeneX and take it to a doctor who is willing to draw the blood. The results will be reported to the doctor. It usually takes about three weeks to get the results back. This could save you time because you could take the results with you to your appointment. Make sure you are tested for the co-infections Babesiosis, both types of Ehrlichiosis, Bartonella, and Mycoplasma. IgeneX can test for all except Mycoplasma. Ehrlichiosis infects the white blood cells. Some people who have it, not all, have a low white blood count from it. Bartonella can cause swollen lymph nodes.
