Abstract

Currently, conventional enzyme immunoassays which use manual gold, and colloidal tests (GICT) are used as a screening tool to detect Treponema pallidum (syphilis), hepatitis B virus (HBV), hepatitis C virus (HCV) and human immunodeficiency viruses (HIV 1/2) in patients undergoing surgery. The present observational, cross-sectional study compared the sensitivity, specificity and workflow characteristics of the conventional algorithm using manual GICT with a newly proposed algorithm that uses automated BIO-FLASH® technology as a screening tool in patients undergoing gastrointestinal (GI) endoscopy. A total of 956 patients were examined for the presence of serological infection markers (HIV-1/2, HCV, HBV, and syphilis). The proposed algorithm using BIO-FLASH® technology was superior in the detection of all markers (100.0% sensitivity and specificity for anti-HIV and anti-HCV antibodies, HBV surface antigen [HBsAg] and syphilis detection) compared with the conventional algorithm based on the manual method (80.0% sensitivity and 98.6% specificity for anti-HIV; 75.0% sensitivity for anti-HCV and 94.7% for HBsAg, and 100% specificity for both markers) in these patients. The automated BIO-FLASH® screening algorithm also reduced the operation time by 85.0% (205 minutes) per day, saving up to 24 hours/week. In conclusion, the use of the newly proposed screening algorithm based on the automated BIO-FLASH® technology can provide an advantage over the conventional algorithms based on manual methods in the screening of HIV, HBV, HCV and syphilis before GI endoscopy.
