The samples were screened for hepatitis B surface antigen (HBsAg), hepatitis C virus (HCV) antibodies, human immunodeficiency virus antibodies\/antigen (HIV Ab\/Ag), and <jats:italic>Treponema pallidum<\/jats:italic> (TP) antibodies using enzyme-linked immunosorbent assay (ELISA). Alanine aminotransferase (ALT) levels were measured using a rapid method. Chemiluminescence immunoassay technology was used to detect five hepatitis B virus (HBV) markers. Polymerase chain reaction was employed to detect HBV DNA, HCV RNA, and HIV RNA. The reactivity rates of each marker were analyzed.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec003\">\n<jats:title>Results<\/jats:title>\n<jats:p>The overall positivity rate for blood testing among donors in this region was 0.76% (4,078\/539,117). The positivity rates for the individual markers were as follows: anti-TP (0.20%)&gt; HBsAg (0.18%)&gt; ALT (0.13%)&gt; anti-HCV (0.085%)&gt; nucleic acid testing (0.080%)&gt; HIV antigen\/anti-HIV (0.079%). No significant differences were observed (P\u2009&gt;\u20090.05). Before 2023, the positivity rates for ALT and HBsAg exhibited occasional fluctuations, followed by a significant decline. Conversely, in 2024, a slight upward trend in the HIV positivity rate was noted.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec004\">\n<jats:title>Conclusion<\/jats:title>\n<jats:p>The current multitiered blood screening and detection strategy in this region exhibits complementary advantages, ensuring effective blood safety. However, the observed slight upward trend in the HIV positivity rate among voluntary blood donors highlights the necessity for enhanced pre-donation counseling and risk assessment for key populations.<\/jats:p>\n<\/jats:sec>","DOI":"10.1371\/journal.pone.0331027","type":"journal-article","created":{"date-parts":[[2025,8,21]],"date-time":"2025-08-21T17:51:12Z","timestamp":1755798672000},"page":"e0331027","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":2,"title":["Analysis
