Is it normal for a doctor to do a Western Blot test even though the ElISA test came back negative? Or is the doctor just trying to cover his/her bases? Is there a standard procedure?
Response from Dr. Frascino
"Standard" testing consists of a screening EIA (antibody test) followed by confirmatory WB (Western Blot) if the EIA is "repeatedly reactive." So whether covering bases or covering his/her ass, it doesn't make much sense to me.
