The question is, why was there an option box for both ELISA and EIA? :wtf:
ELISA (Emzyme-linked Immunosorbent Assay) is also known as EIA (Enzyme Immunoassay).

It is no more accurate or reliable than any other assay screen. Samples that fail would still have to go to the GC/MS for confirmation and quantification.
Burnt Toast Reviewed by Burnt Toast on . omg elisa and eia test They sent my urine to the lab today and elisa and eia were both checked off. I cant find anything good on elisa but some things are saying like 1 ng/ml cutoff or 10 ng/ml cutoff. Does anybody know anything about this test. Rating: 5
