Urgent Care Center of Westmont, also known as Immediate Care Center of Westmont, has a team led by board-certified physicians. At the front desk, you only need to say you would like testing. In a private room, a clinician asks about symptoms, partners and timing, and examines any area of concern. Samples such as urine, a blood draw or a swab are collected on site by our clinical team. Nothing is self-collected. A clinician shares your results with you directly.
Some of our staff speak Spanish. Our STD testing service page lists every infection we test for, and our HIV testing page explains that test.

How soon should I retest after treatment?
For chlamydia and gonorrhea, the CDC recommends retesting about three months after treatment, even if your partners were treated, because repeat infections are common. For syphilis, follow-up testing confirms treatment worked. Your clinician will give you a plan.
Should I test before we stop using condoms with a new partner?
It is a good idea. The CDC lists getting tested together, sharing results and staying in a mutually monogamous relationship with a partner who has tested negative as ways to lower risk. Keep window periods in mind if either of you had a recent exposure, since an early test may need repeating.
