What Mosaic Diagnostics does

Mosaic Diagnostics (MosaicDX) is a privately held clinical laboratory founded in 1996 in Overland Park, Kansas, that provides functional medicine diagnostic testing primarily to licensed healthcare practitioners and the patients they serve. The company rebranded from The Great Plains Laboratory to Mosaic Diagnostics in 2023 and now markets under the MosaicDX name across the United States and internationally through MosaicDX International. The company's core technology stack centers on advanced laboratory methodologies — LC-MS/MS (liquid chromatography tandem mass spectrometry), MSQPCR (Mold-Specific quantitative PCR, licensed from the EPA), ICP-MS (inductively coupled plasma mass spectrometry), ELISA, IFA, and dPCR — applied across multiple specimen types including urine, blood, hair, stool, and environmental dust.

MosaicDX operates a broad test portfolio organized into six functional assessment categories: Toxins (MycoTOX Profile®, TOXDetect Profile®, Glyphosate Test, Heavy Metals), Metabolic Assessment (Organic Acids Test, Amino Acids Test, Omega-3 Index), Lyme + Co-Infections (Nanotrap®-based and dPCR assays), Allergy and Food Sensitivities (IgG and IgE panels), Gastrointestinal Health (Comprehensive Stool Analysis, Microbiology), and Hormones. The portfolio also includes bundled combination panels such as the EnviroTOX® suite and the Mycotoxin Body + Home Panel, which pair biological mycotoxin measurement with environmental dust mold testing. Proprietary differentiation is anchored in parts-per-trillion LC-MS/MS sensitivity for mycotoxins, EPA-patented MSQPCR for 36-species environmental mold detection, and multi-specimen heavy metals testing covering up to 39 analytes.

Commercially, MosaicDX sells via a practitioner-direct model in which providers open accounts on the MosaicDX Portal, order kits for office inventory or drop-ship to patients, and access results through the portal alongside complimentary clinical education consults for result interpretation. A patient-facing self-serve portal and a Find a Practitioner directory support direct-to-consumer ordering and act as a referral pathway to acquire new practitioner accounts. The company distributes internationally through MosaicDX International with a documented restriction on New York state. Pricing is not publicly disclosed; revenue is generated per test order, with CPT codes published for billing reference. The Preferred Partner Network integrates complementary tools such as ToxiMapp (environmental exposure intelligence) and inFoods IBS. Leadership is headed by CEO Scott Mattivi, succeeding founder William Shaw, PhD.

Core offering

Mosaic Diagnostics (formerly The Great Plains Laboratory, rebranded in 2023) is a CLIA-certified specialty clinical laboratory that provides functional medicine diagnostic testing on patient samples including urine, blood, hair, stool, and dust. The lab analyzes these specimens for organic acids, mycotoxins, environmental toxins, heavy metals, food sensitivities, gut microbiome markers, hormones, and tick-borne pathogens, returning interpreted reports to ordering practitioners and patients. The lab operates two distinct order channels — a practitioner portal for B2B clinicians and a self-directed patient portal — with MosaicDX International serving as the international distribution arm.

Partnerships

Two partnerships are on record, tiered core.

• inFoods IBScoreStrategic or Co-development PartnerinFoods IBS is part of MosaicDX's Preferred Partner Network. It is a clinically studied, laboratory-developed test (LDT) that identifies IBS-specific food triggers. The partnership provides MosaicDX practitioners with an additional diagnostic tool for patients with irritable bowel syndrome, complementing MosaicDX's existing GI and food sensitivity testing portfolio. Patients can find relief through a drug-free solution guided by testing.
• ToxiMappcoreTechnology or IntegrationToxiMapp is a location-based environmental exposure intelligence platform within MosaicDX's Preferred Partner Network. It helps practitioners identify which toxins their patients may have been exposed to — by address, across air, water, and soil — for more targeted decision-making. The partnership integrates with MosaicDX's TOXDetect Profile and other toxicant testing to provide environmental exposure context for test results.

Direct peers

• Genova Diagnostics: Genova Diagnostics is a leading specialty clinical laboratory focused on functional medicine testing, offering assessments in GI, hormones, nutritional status, toxic exposures, and cardiometabolic health — directly overlapping MosaicDX's practitioner-directed test menu and patient-pay model.
• Doctor's Data: Doctor's Data is a specialty lab offering comprehensive stool analysis, heavy metals testing, and environmental toxin panels — closely comparable to MosaicDX's GI, metals, and toxic exposure offerings for functional and integrative practitioners.
• RealTime Laboratories: RealTime Laboratories specializes in mycotoxin testing using mass spectrometry, competing directly with MosaicDX's MycoTOX Profile in the mold-illness practitioner segment served by functional and integrative medicine providers.
• Vibrant Wellness: Vibrant Wellness is a clinical lab offering a broad menu of specialty panels (toxins, food sensitivities, hormones, Lyme, gut) — directly competitive with MosaicDX across multiple functional medicine categories.
• Cyrex Laboratories: Cyrex Laboratories focuses on food sensitivity/autoimmune and environmental reactivity arrays, overlapping with MosaicDX's IgG/IgE allergy and food sensitivity testing for functional practitioners.
• Diagnostic Solutions Laboratory: Diagnostic Solutions Laboratory offers GI microbiome and functional medicine panels (e.g., GI-MAP), overlapping with MosaicDX's Comprehensive Stool Analysis and gut health offerings for similar practitioner customers.
• Precision Analytical (Equilife): Precision Analytical (Equilife) is the creator of the DUTCH hormone test, serving the same functional/integrative practitioner base as MosaicDX with a strong specialty franchise in hormones and metabolites.

Emerging players

• US BioTek: US BioTek is a specialty lab offering IgE/IgG food allergy and environmental panels; while smaller in menu breadth, it competes with MosaicDX in the food and mold allergy testing categories.

Broad incumbents

• Quest Diagnostics: Quest Diagnostics is a large national reference laboratory offering broad clinical and specialty testing; while not a functional-medicine specialist, it competes for the same physician ordering decisions and increasingly enters specialty panels relevant to MosaicDX.
• Labcorp: Labcorp is one of the largest US clinical laboratories with broad routine and specialty menus; its scale, insurance coverage, and reach make it the dominant incumbent against which specialty labs like MosaicDX differentiate.
