Gonorrhea: why throat and rectal tests sometimes matter
Read moreClose
The CDC says gonorrhea can infect the genitals, rectum and throat. It is usually diagnosed with a urine sample, but after oral or anal sex your clinician may also swab the throat or rectum, since a urine test would not check those sites.
Most women with gonorrhea have no symptoms, and mild ones can be mistaken for a bladder or vaginal infection.
Men with symptoms often notice burning when urinating or discharge from the penis.
Rectal infections may cause no symptoms, or discharge, itching, soreness or bleeding.
The CDC notes drug-resistant strains are increasing, so it matters to take all medicine as prescribed and to be retested about three months after treatment.

A judgment-free visit led by board-certified physicians
Read moreClose
Urgent Care Center of Westmont, also known as Immediate Care Center of Westmont, has a team led by board-certified physicians. In a private exam room, your clinician asks about symptoms, partners and the kinds of sex you have had. These are routine questions. Depending on your answers, samples may include urine, blood, or a swab of the genitals, throat, rectum or a sore.
When results are ready, a clinician explains them privately. If anything is positive, they recommend treatment, which may include prescription medicine when appropriate, and talk about telling partners. Our STD testing service page lists every infection we test for.

How far is your STD testing clinic from Lemont, IL?
About 8.5 miles north of Lemont in a straight line. Most people take Lemont Road to I-55 and exit at Cass Avenue, or take IL-83 north to Ogden Avenue. Each route ends at one of our two Westmont, IL clinics.
Do I need a throat swab for an STD test?
Only if it fits your history. The CDC says gonorrhea can infect the throat and rectum, and a urine test would not detect infection there. If you have had oral or anal sex, tell your clinician so they can decide whether to swab those sites.
Can I do the STD test at home and mail it in?
Not through our clinics. We collect every sample on site during your visit, in a private exam room. That way a clinician can examine any symptoms and choose the right tests and body sites.
Does it matter which county I live in?
Not for your visit. We see patients from Cook, DuPage and Will counties and beyond. What matters for billing is your insurance plan, so call (630) 324-6825 to confirm coverage, or ask about self-pay pricing from $125.
Should my partner be tested too?
Often, yes. If you test positive, the CDC advises that partners be treated at the same time so the infection is not passed back and forth, and that sex wait until everyone has finished treatment. Your clinician can talk through how to tell a partner.
