The Dr who can diagnose and treat Lupus is a
Rheumatologist. Other docs, like Primary, Hematologist, Surgeon, etc are not trained to diagnose a tricky disease like Lupus or other similar auto-immune diseases.
Lupus is not diagnosed by any one test -- it is very tricky and you need to have at least 4 of 11 indications of Lupus before a reputable rheumy will diagnose you. Many times a clear diagnosis takes a year or two to present itself.
In the meantime a rheumy will probably start you on plaquenil and/or prednisone to slow development of the disease and get the inflammation from the disease under control.
One way to get a knowledgeable rheumy is to visit
www.lupus.org, locate your local chapter, then call and ask about
what local Drs are on their advisory board. These are the Drs most interested in and experienced with Lupus.
