Nantong Union Bio-Technology

Nantong Union Bio-Technology is a China-based in vitro diagnostics and medical test manufacturer focused on rapid self-test and point-of-care style diagnostic products. Publicly available information indicates the company develops, produces, and sells biological reagents and diagnostic test strips, with notable commercial products in fertility and women's health testing such as early pregnancy, ovulation, and vaginitis tests. The company appears to market products under the "Sisters" brand and emphasizes export-oriented manufacturing. Available evidence suggests it operates as a commercial diagnostics manufacturer rather than a therapeutic drug developer, so traditional biotech pipeline, target, and clinical-stage fields are limited. Its business profile is most consistent with an active private healthcare company serving consumer and diagnostic markets.
