Pathways of Pella delivers STI testing (gonorrhea, chlamydia, syphilis, herpes, hepatitis C, and HIV) with every service free of charge and appointments required; bacterial infections are treated the same visit they're diagnosed.

Read full overview Show less

Every Test and Treatment Carries Zero Cost

Pathways of Pella runs its entire STI program without fees, no sliding scale, no partial charge, no cost at any point. That means the herpes swab, the hepatitis C draw, the HIV test, and any same-visit bacterial treatment are all covered at the same rate: nothing.

Herpes and Hepatitis C Tested Alongside the Standard Four

Where many panels stop at gonorrhea, chlamydia, syphilis, and HIV, Pathways of Pella adds herpes and hepatitis C. Both drawn and processed through the clinic itself. Herpes testing requires a specific sample collection method distinct from blood-based STI draws, and having that capability in-house means the full six-infection panel runs in a single appointment.

Reading these numbers: reported case rates only count infections that were actually tested for and diagnosed, so they track local screening effort as much as true spread: a higher rate can reflect more testing, a lower one less. Either way, most STIs cause no symptoms, so treat the figures above as context rather than a verdict, and test on the CDC's schedule regardless of how your area looks.

Congenital syphilis is the fastest-rising STI: what to test, and when

Congenital syphilis, passed from parent to baby in pregnancy, is the fastest-rising STI in the country. U.S. cases climbed from 2,163 in 2020 to 3,882 in 2023. It is almost entirely preventable: the CDC recommends a syphilis test at the first prenatal visit, and every clinic and lab listed for Marion County tests for syphilis.

Local context

About Knoxville, IA

Knoxville's rhythm turns on manufacturing, farming, and the seasonal work that keeps the town moving. The kind of place where people show up for their shifts and know what they're doing matters. That practical mindset carries into health too. STI testing in and around Knoxville is straightforward: available through clinics listed on this page, confidential, and designed to fit into a workday or weekend without fuss.

The modest cost of care here means screening stays accessible even when budgets are tight. The town draws young adults in their late teens through their thirties (people starting jobs, building lives, or passing through) and that population benefits from knowing where to go when routine testing matters. Testing stays between you and the clinic; results don't circulate, and no one at work or around Youngs Park needs to know you've been screened. That separation is built into how these services work.

Finding a testing site near Colonial Terrace or along Lincoln Street takes only a quick look at the directory. Walk in, get tested, walk out with peace of mind. Knoxville's providers understand that sexual health screening isn't complicated: it's just necessary, and it happens quietly here like everything else that keeps the town running.

Use this as a per-test benchmark before you pay out of pocket, or see the full guide to STD test costs for insurance, free, and at-home options.

Confidentiality & consent in Iowa

Minor consent and partner treatment (EPT) under state law, plus how to test privately

Two things that actually depend on Iowa law: who can consent, and whether partners can be treated without their own visit. Everything else about testing privately is the same nationwide (see below).

Can a minor consent on their own?

In Iowa, a minor of any age can consent to confidential STI testing and treatment on their own; a parent may be notified only in the case of a positive HIV test result.

Can my partner be treated too? (EPT)

Iowa permits Expedited Partner Therapy (EPT): if you test positive for chlamydia or gonorrhea, your provider can give you medication (or a prescription) to pass to your partner, no separate exam or appointment needed for them.

Keeping a test private works the same in every state. Whether an STD test shows on insurance (the EOB), how to test anonymously, and self-pay options that leave no insurance trail don’t change by location.
