Sexually transmitted infections (STIs)—including Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis, syphilis, HIV-1/2, HBV/HCV, HSV-1/2, HPV, and Mycoplasma genitalium—require fast, sensitive diagnostics to break transmission chains and guide targeted therapy. At Southern Medical Supplies Limited (SMSL), we deliver an end-to-end STI menu spanning syndromic and targeted NAAT/RT-PCR (first-void urine, endocervical/urethral, vaginal, rectal, and pharyngeal swabs), 4th-generation HIV Ag/Ab with differentiation and viral load, comprehensive syphilis algorithms (treponemal IgG/IgM EIA with RPR/TPPA confirmation), HBV/HCV serology and NAT, type-specific HSV serology/PCR, HPV high-risk genotyping, culture with susceptibility for gonococcal resistance monitoring, and CLIA/ELISA plus rapid point-of-care options—supported by appropriate collection media, QC materials, and clear reflex pathways. Our platforms come from a broad network of trusted partners—EUROIMMUN, Ansh Labs, Randox, Streck, Bio-Rad, Abbott, Roche, Siemens Healthineers, Qiagen, bioMérieux, Cepheid, Werfen, Globe Scientific, ELGA LabWater, LW Scientific, Sebia, LTA SRL, Acrobiotech, MAKOL Innovacion Medica, Rayto Life and Analytical Sciences, Diazyme, Hardy’s Diagnostics, and Teco Diagnostics—ensuring the sensitivity, specificity, and reproducibility clinicians need for accurate detection, antimicrobial stewardship, and improved patient outcomes.
