SEXUALLY TRANSMITTED DISEASES (STDs)

STDs are illnesses that spread by sexual contact and are an important global health priority because of their devastating impact on women and infants. There are more than 30 known pathogens that cause STDs which include bacteria (gonorrhea, syphilis, chlamydia), parasites (trichomoniasis), and viruses (HPV, herpes, HIV). One of the major concerns regarding the control of STDs is that the majority of infections remain asymptomatic and infected individuals can unknowingly pass on the infection for several years. Early and rapid diagnosis of an STD increases the chance to limit effects of the disease.

There are five main methods for the diagnosis of STDs which include: 1) culture; 2) microscopy; 3) detection of antigens or enzymes; 4) detection of nucleic acid sequences (NAAT); and 5) detection of antibodies. Of the five approaches, the assays that provide the most rapid diagnosis, specifically the detection of antibodies by rapid serologic methods, and specific detection of cellular components, including antigens, enzymes, or nucleic acid sequences (especially with amplification), have gained the most acceptance. Meridian offers a broad range of antibodies and antigens especially for ELISA, Lateral Flow, CLIA, bead-based assays and IHC.
