Phlebotomist Salary in Colorado

Denver metro. UCHealth, anchored by University of Colorado Hospital on the Anschutz Medical Campus in Aurora, is the largest health system in the state and pays at the top of the local range for academic draw roles, including blood bank and oncology phlebotomy. HealthONE, the HCA network, operates the most hospitals in the metro (Presbyterian/St. Luke's, Swedish, Rose, Sky Ridge and others), Denver Health is the safety-net academic system in the city, and Intermountain Health (which absorbed SCL Health) runs Saint Joseph in Denver and Lutheran in Wheat Ridge. Kaiser Permanente Colorado and Children's Hospital Colorado in Aurora, the state's major paediatric employer, round out the metro.

Colorado Springs. UCHealth Memorial Hospital is the largest employer in the Springs, with CommonSpirit Health's Penrose-St. Francis network the other major system. Fort Carson and the surrounding military medical facilities add federal employment for the occupation.

Boulder and Fort Collins. Boulder Community Health anchors Boulder alongside UCHealth's Longs Peak and Broomfield hospitals. In Fort Collins and the rest of northern Colorado, UCHealth's Poudre Valley Hospital and Medical Center of the Rockies compete with Banner Health, which runs Banner Fort Collins Medical Center and North Colorado Medical Center in Greeley.

Reference labs, blood centers, and plasma. Quest Diagnostics and Labcorp operate patient service centers statewide, and hospital and reference labs run their own draw stations. Vitalant (the region's main blood center) hires apheresis and donor-collection phlebotomists, and CSL Plasma, Grifols and Octapharma run donor-collection centers that hire high-volume phlebotomists and often train from zero.

Colorado's state mean of $48,520 is about $3,000 above the national mean of $45,520 in nominal terms. The BEA Regional Price Parity for Colorado is 103.1 for 2024, meaning the state is about 3 percent more expensive than the US average, so the real-purchasing-power value of the state mean is roughly $47,060 in national-average dollars, still above the national figure. That statewide RPP masks a wide internal spread: the Denver-Boulder Front Range and the mountain resort towns are far more expensive than the state average, while the Eastern Plains and parts of the Western Slope are cheaper.

Colorado levies a flat individual income tax rather than graduated brackets: 4.40 percent of federal taxable income for the 2025 tax year. Because the tax base starts from federal taxable income, the federal standard deduction (about $15,000 for a single filer in 2025) comes off first, so a phlebotomist earning the state mean pays roughly $1,450 to $1,550 a year in Colorado income tax, an effective rate near 3 percent. Colorado's TABOR surplus mechanism can temporarily lower the rate in high-revenue years, as it did to 4.25 percent for the 2024 tax year, and also returns money through sales-tax refunds on the state return.

Where you live inside Colorado matters more than the statewide averages suggest. The Denver-Boulder corridor pays the most but carries the highest housing costs; Colorado Springs and Fort Collins pay near the state mean at a somewhat more moderate cost of living; and the mountain resort communities pay competitively but face some of the highest housing costs in the country relative to local wages. Run the specific numbers for your metro and housing situation.

Colorado does not require a state phlebotomy license or state certification. Unlike California, Nevada, and Washington, which regulate the role at the state level, Colorado lets employers set their own credential requirements. In practice, most hospitals and reference labs prefer or require a national certification.

The accepted national credentials are ASCP PBT (American Society for Clinical Pathology), NHA CPT (National Healthcareer Association), AMT RPT (American Medical Technologists), and NCCT NCPT (National Center for Competency Testing). Academic and large systems such as UCHealth, Children's Hospital Colorado and Denver Health tend to prefer ASCP PBT for blood bank and oncology placements at hire, while community hospitals, physician offices, and plasma centers accept any of the major credentials and often train and certify from zero.
