Direct Competitive Enzyme-Linked Immunosorbent Assay (ELISA). Evaluation of a newly designed sandwich enzyme linked immunosorbent assay for the detection of hydatid antigen in serum, urine and cyst fluid for diagnosis of cystic echinococcosis.

ELISA is a common laboratory testing technique that detects and counts certain , proteins and in bodily fluid samples. This includes , pee, saliva (spit) and cerebrospinal fluid (CSF). “ELISA” stands for “enzyme-linked immunosorbent assay.” Another name for it is an EIA test. Researchers consider ELISA to be the gold standard of immunoassays.

3.4. Comparison of VIDAS ® DENGUE NS1 Ag Assay with Competitor Assays. The positive agreement of the VIDAS ® DENGUE NS1 Ag to the NS1 FOCUS ELISA (used as reference test) was very high (97.6%; 95% CI [91.5–99.7]) (Table 3). This is in line with the comparably high sensitivity of both assays (Table 2).

Several types of ELISAs have been developed: direct ELISA, indirect ELISA, sandwich ELISA,.
