Runbio Biotech

Runbio Biotech is a China-based in vitro diagnostics and rapid test manufacturer focused on immunoassay-based products for clinical, laboratory, retail, and home use. The company is best known for fertility testing products sold under the DAVID brand and also markets rapid tests for infectious diseases, sexually transmitted infections, tumor markers, and drugs of abuse. Runbio appears to operate as a commercial-stage diagnostics business rather than a therapeutic drug developer, with GMP/ISO-certified manufacturing and OEM/private-label capabilities. Publicly available sources indicate the company later adopted the name Equinox Biotech Co., Ltd. while continuing its diagnostics manufacturing business.
