A Title X tag flags centers funded for confidential family-planning services; confirm current participation when you call.

ASL on Staff, Interpretation for Dozens More

American Sign Language is available as a direct, staff-level service, not routed through an app or a handset, alongside Spanish and interpretation for non-English languages beyond those two. For Deaf patients, that means a clinician can take a history and explain results without an intermediary shaping the conversation.

Title X Covers Minors With Legal Confidentiality

Planned Parenthood of the Rocky Mountains operates under Title X, which makes its family planning and STI services legally confidential for minors: meaning a visit, a result, or a prescription does not have to appear on a parent's insurance explanation of benefits.

PrEP, PEP, and DoxyPEP Prescribed and Managed Here

For anyone without a regular primary-care provider, Planned Parenthood of the Rocky Mountains holds PrEP, PEP, and DoxyPEP under one clinical roof. Prescribing and managing all three rather than sending patients elsewhere to establish care before accessing them. Uninsured patients have a dedicated PrEP assistance pathway on-site.

Ryan White Funding Keeps HIV Care Continuous

STRIDE carries Ryan White funding, which means HIV care doesn't pause at a positive result. The same center that runs the test manages the treatment. That continuity eliminates the gap between diagnosis and a stable care relationship.

PrEP and PEP Prescribed On-Site in Aurora

STRIDE prescribes both PrEP and PEP directly, so prevention medication is a clinical conversation at your appointment, not a separate errand. That means anyone starting or maintaining HIV prevention has a prescribing provider already in the room.

Herpes Testing Included Beyond the Standard Four

Gonorrhea, chlamydia, and HIV are standard nearly everywhere. Herpes testing routinely isn't. STRIDE runs it alongside the rest of the panel, so one appointment captures infections that a shorter list would leave unexamined.

That standing capacity makes the clinic a reliable first stop for patients whose primary language isn't English.

Herpes and Hepatitis C Alongside the Standard Four

People without a regular primary care provider often have nowhere to send hepatitis C or herpes testing, Denver Health holds both in the same appointment. That means one visit, one sliding-scale bill, and answers on infections that often go undetected for years when care is fragmented.

PrEP Prescribed and Monitored On-Site in Denver

Starting PrEP at Denver Health means a clinician orders baseline labs (HIV status, kidney function, hepatitis B screening) then writes for daily oral medication and schedules follow-up monitoring every three months. PEP is also available; both are managed by staff who track dosing history and lab trends over time, not handed off after the first prescription.

Full Clinical Care Conducted Entirely in Spanish

For someone navigating a sliding-scale billing conversation, a treatment decision for a bacterial STI, or a PrEP initiation discussion, conducting that in Spanish, with the clinician directly, changes the quality of the exchange. Denver Health delivers the full clinical encounter in Spanish, not just intake paperwork.

Spanish and Interpretation Keep Care Moving

When a diagnosis arrives in a language someone is still processing, the real cost isn't discomfort: it's missed follow-up, incomplete treatment courses, and questions that never got asked. UCHealth Aurora pairs Spanish-speaking staff with interpretation services for other languages, so nothing critical gets deferred to a second visit.

Ryan White Funding Covers HIV From Test to Treatment

UCHealth Aurora carries Ryan White funding, which means HIV services run from initial testing through ongoing medical treatment as a single, connected program, so a new diagnosis doesn't require rebuilding a care relationship somewhere else.

UCHealth Aurora prescribes PrEP, PEP, and DoxyPEP, covering both ongoing HIV prevention and the newer bacterial STI prevention protocol. Meaning someone can leave a single appointment with a personalized prevention regimen already in hand.

Every Appointment Billed at Zero Dollars

When cost becomes the reason someone delays care, an untreated bacterial infection compounds and an HIV diagnosis stretches further from support. Colorado Health Network eliminates that pressure entirely: every service, from the initial test through PrEP prescriptions and DoxyPEP, carries no charge.

Spanish Spoken Fluently, Not Routed Around

Many clinics field non-English speakers through ad hoc arrangements that slow the visit and flatten the conversation. Colorado Health Network offers Spanish-language services directly alongside interpretation for other languages, so the clinical exchange, including counseling and medication education, runs at full depth.

Ryan White Funding Anchors HIV Care End-to-End

Ryan White funding at Colorado Health Network supports the full arc of HIV care, from rapid and conventional testing through ongoing medical treatment and medication adherence counseling, which means a new diagnosis doesn't require building a second care relationship somewhere else.

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 Denver County tests for syphilis.

Data & references

About Denver, CO

City Park sits just west of the museum strip on East Colfax Avenue, one of Denver's more recognizable stretches, and for residents near Montbello or The Vistas, reaching any clinic can mean navigating I-70 or North Quebec Street during peak hours rather than walking out the door.

Denver splits almost evenly between owners and renters, and with typical rents running above twelve hundred dollars a month, a large share of households are managing housing costs that leave little room for anything that feels optional. That kind of budget pressure is exactly why the range of options listed on this page matters: younger adults in their late teens and twenties make up a substantial portion of the city, and when people in that phase of life are also working, since nearly three in four residents are in the labor force, scheduling around clinic hours becomes a real constraint rather than a minor inconvenience. Average households here skew larger than the national norm, and with fewer than half of adults married, a meaningful number of people are in the relationship-formation years when routine STI screening is most relevant.

About a third of Denver households clear six figures, which leaves the majority working with tighter budgets. Several options listed here offer sliding-scale fees or accept Medicaid, so a renter near Sandown paying market-rate rent on a single income still has a path to low-cost or no-cost testing without absorbing another monthly bill.

What each STD test costs

Medicare reference prices per lab test, a benchmark before you pay out of pocket

These are the federal Medicare reference prices for processing each lab test. Public clinics and the community health centers serving Denver often test free or on a sliding scale; private labs and at-home kits bundle several tests into one fee. 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 Colorado

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

Two things that actually depend on Colorado 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 Colorado, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.

Can my partner be treated too? (EPT)

Colorado 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.
