📞 Call Now for Confidential TestingRegular STD testing is a vital part of sexual health for people in Colonia and surrounding Middlesex County. Many sexually transmitted infections are asymptomatic, meaning you can carry and spread an infection without obvious signs. The CDC recommends regular screening for sexually active women under 25 for chlamydia and gonorrhea, annual HIV testing for those at risk, and more frequent testing for people with multiple partners. Nationally, about 1 in 5 Americans has an STI—local public health clinics in central New Jersey report ongoing cases of chlamydia, gonorrhea, and syphilis, particularly among younger adults. Early detection leads to easier, faster treatment, prevents long-term complications like infertility for bacterial infections, and reduces transmission to partners. Testing also reduces stigma by normalizing care and encouraging open conversations with partners and providers. In Colonia, our goal is to make STI testing accessible, confidential, and straightforward—walk-in STD test options, rapid STD testing processes, and secure result delivery help you get same-day STD testing and same-day STD results when possible. If you have a new partner, symptoms, or recent exposure, schedule a confidential test and get medically accurate guidance tailored to your needs.
