Precision diagnostics,
delivered with care.
For over 15 years, Diamond Blood Testing has combined certified laboratory expertise with modern technology to deliver diagnostic clarity thousands of patients and physicians trust.
A modern laboratory built around the patient.
Diamond Blood Testing was founded to close the gap between clinical accuracy and patient experience. From day one, we set out to build a laboratory that felt as thoughtful as it was rigorous — one where every workflow, from booking to reporting, would be designed around real human beings.
Today we operate a fully CLIA-certified and CAP-accredited laboratory serving individuals, private physicians, wellness clinics and corporate programs. Our specialists process hundreds of thousands of samples every year across preventive wellness, chronic disease monitoring and specialized diagnostics.
We invest continuously in modern analyzers, validated methodologies and secure digital infrastructure so every result you receive is worthy of the decisions built on it — and every patient who walks through our door feels genuinely cared for.
Our Mission
To make hospital-grade diagnostic testing radically more accessible, clearer and more compassionate — so every patient can act early on their health with confidence.
Our Vision
To become the most trusted independent laboratory in the country: recognized for uncompromising quality, deeply human care, and the technology that makes both possible at scale.
