Cleveland HeartLab

What Cleveland HeartLab does

Cleveland HeartLab, Inc. is a specialty clinical laboratory headquartered in Cleveland, Ohio, focused exclusively on cardiometabolic disease testing. Founded in 2000 by Stanley Hazen and Jake Orville, the company operates as the Quest® Cardiometabolic Center of Excellence™ at Cleveland HeartLab® under the corporate umbrella of Quest Diagnostics Incorporated (NYSE: DGX), a wholly-owned subsidiary structure that provides national laboratory infrastructure, billing systems, and provider network reach.

The company's core offering is a proprietary multimarker test menu spanning inflammation biomarkers (F2-Isoprostanes, hsCRP, Oxidized LDL, Lp-PLA2 Activity, Myeloperoxidase, Microalbumin, ADMA/SDMA), advanced lipid testing (HDL Function Panel with HDLfx pCAD Score, NMR LipoFraction, Apolipoprotein B/A1, Small-Dense LDL, Lipoprotein(a)), metabolic markers (TMAO, Adiponectin), vitamin and supplement testing (OmegaCheck™, CoQ10, Vitamin D), genetic assays (ApoE genotyping, CYP2C19 polymorphism), and additional cardiovascular markers (AspirinWorks®, Galectin-3, High Sensitivity Troponin T). These assays are performed at the company's Cleveland laboratory using proprietary chemistry methods and are supported by clinical education, peer consultation services, and an extensive clinical references library.

Commercially, Cleveland HeartLab operates a B2B sales-led model targeting healthcare providers — physicians, cardiologists, primary care practices, and clinical groups — who order tests on behalf of patients. Specimens are collected at provider offices or Quest Diagnostics Patient Service Centers and shipped to Cleveland for analysis. Tests are billed through standard insurance, Medicare, or Medicaid reimbursement channels. Distribution occurs through direct sales relationships, the Cleveland HeartLab web portal, and integration with Quest Diagnostics' Quanum Lab Services Manager. The company holds CLIA certification and HIPAA compliance, and prior to its acquisition by Quest Diagnostics had raised approximately $48M in venture funding between 2010 and 2016.
