Background: COVID-19 pandemic created an unprecedented demand for reagents and diagnostic tools to confirm cases. Thus, the development of a robust in-house test is considered high importance. Within few days after exposure, human body produces specific antibodies that recognize surface proteins invading SARS-CoV-2 virus1. Therefore, virus immunoglobulins are neutralizing their appearance in bl...

Hepatitis B merupakan penyakit inflamasi dan nekrosis sel hati yang disebabkan oleh infeksi virus hepatitis (VHB). Kehadiran anti-HBs faktor penting dalam diagnosis prognosis VHB. Rapid test adalah salah satu metode pemeriksaan selain ELISA untuk mendeteksi adanya anti-HBs, lebih praktis penggunaan ekonomis. Tujuan penelitian ini mengetahui nilai sensitivitas spesifisitas rapid Intec® terhadap ...

A urease-based enzyme-linked immunosorbent assay (ELISA) has been developed for the detection of reagin antibodies in serum. Visuwell Reagin (ADI Diagnostics Inc., Rexdale, Ontario, Canada) is a non-treponemal screening test for the serodiagnosis of syphilis which has the benefits of large batch testing, automatability, and objective interpretation of results. Unheated, undiluted sera are incub...

I evaluated an enzyme-linked immunosorbent assay (ELISA) and agar gel immunodiffusion (AGID) test simultaneously for the detection of bovine leukemia virus (BLV) antibodies. Total 1,293 serum samples were tested for ELISA and AGID test and the results were compared. The results of ELISA and AGID agreed by 1,156 out of 1,293 (89.4%). All of AGID-positive 356 sera were positive by ELISA. However,...

An indirect enzyme linked immunosorbent assay (ELISA) was developed for the diagnosis of allergy to a house dust mite, Dermatophagoides farinae. The efficacy of the ELISA was then evaluated against a prick test using a commercial allergen. Eighty five suspected allergic rhinitis patients from the Otorhinolaryngology Department, Kuala Lumpur General Hospital, were tested with the ELISA and prick...

To establish a definite diagnosis for pulmonary hydatid disease, combination of radiology and serology is useful. In this study, 19 preoperative sera from patients with surgically confirmed pulmonary hydatidosis, 40 sera from patients with other parasitosis and pulmonary diseases, and 20 sera from healthy donors were evaluated using 4 different serological tests, i.e., the commercial ELISA (ELI...

CITE enzyme-linked immunosorbent assay (ELISA) was an unacceptable screening test for failure of passive transfer because of poor sensitivity. SNAP ELISA and glutaraldehyde coagulation tests are more appropriate screening tests. Specificity of the SNAP ELISA is better than the glutaraldehyde coagulation test. A second confirmatory test should be considered when using the glutaraldehyde coagulat...
