Lab options in Colorado

Orders placed from Colorado can be processed through Quest Diagnostics (the default) or Labcorp, depending on the specific test and your preference. Both maintain extensive networks of patient service centers across the state — most TestWell customers find a location within a 15-minute drive.

For most common tests, both Quest and Labcorp offer equivalent quality. If you have a preference (existing relationship with one lab, or one is meaningfully closer), you can specify lab routing during checkout.

Nearly all of Colorado's patient service centers line up along the Front Range — Denver and Aurora have the deepest coverage, with steady options through Colorado Springs and up to Fort Collins. Colorado skews athletic in what it orders: iron and ferritin checks (endurance training at altitude), testosterone panels, and vitamin D are disproportionately popular here compared with other states. Mountain-town residents typically order first and draw on their next Front Range trip, since the requisition works at any location.

Major cities served: Denver, Colorado Springs, Aurora, Fort Collins, plus dozens of additional cities and towns. Use the lab finder to locate the closest patient service center to your ZIP code.

Common questions in Colorado

How much does a blood test cost in Denver without insurance?

Through TestWell, individual tests start at $14.99 and the most-ordered panel (General Wellness) is $89.99 — drawn at the same Denver-area Quest or Labcorp centers that hospital systems use, where hospital-billed equivalents commonly run 3-6x higher. Checkout shows one flat price plus the $6 physician-review fee.

I train at altitude — which tests do Colorado athletes usually order?

Ferritin and a full iron panel are the classics (altitude training raises red-cell demand and unmasks low iron stores), alongside vitamin D, testosterone, and a CBC. The Fitness & Performance Panel bundles the core set; results include reference ranges and trend tracking so you can retest across a training block.
