Company profile
researched Aug 2026Mosaic Diagnostics, operating as MosaicDX, is a specialty clinical laboratory focused on functional and precision health testing intended to help practitioners identify root causes of complex, chronic conditions. Its catalog is organized by functional assessment area and includes metabolic and nutritional panels (Organic Acids Test, Amino Acids Test, Omega-3 Index Complete), environmental and mold toxin panels (TOXDetect Profile, MycoTOX Profile, EnviroTOX suite of panels, and a Mycotoxin Body + Home Panel), Lyme and co-infection testing (Lyme Borrelia Direct Detect using Nanotrap, Bartonella IgG Detect by IFA, and a Tickborne BBB Direct Detect 3-day dPCR panel for Bartonella, Babesia and Borrelia), allergy and food sensitivity testing (IgG Food MAP with Candida + Yeast on dried blood spot, IgE Mold Allergy, IgE Food Allergy Advanced), gastrointestinal testing (Comprehensive Stool Analysis, Microbiology stool profile), and salivary hormone panels covering sex and stress hormones.
Alongside testing, the company runs an education and clinical support program. Practitioners with an active MosaicDX account can book one-on-one virtual consults with clinical educators covering result interpretation, follow-up testing strategy, and test selection. The clinical development team includes naturopathic doctors, medical doctors, doctors of clinical nutrition, and registered dietitians, and the company publishes webinars, blogs, case studies, resource guides and specimen collection instructions. The company was formerly known as Great Plains Laboratory.
Business model
MosaicDX sells laboratory testing through licensed healthcare practitioners rather than directly to consumers. Practitioners open an account, order tests via the MosaicDX portal, and the company ships collection kits directly to patients; samples are returned to the laboratory and results are returned in 7-10 business days. Clinical consults with the company's clinical educators are available to account holders as a support layer around the testing.
Revenue is generated from practitioner-ordered laboratory test panels across toxin, metabolic, allergy, gastrointestinal, hormone and tickborne categories.
Traction
Public materials cite practitioner adoption through case studies and testimonials from clinicians in the United States and Europe, and an ongoing webinar and educational content program; no revenue, volume or customer-count figures are published.
Latest developments
The company is promoting a Mycotoxin Body + Home Panel across its site and continues to publish practitioner education content, including a webinar on organic acids testing in pediatric anxiety, OCD and neurodevelopmental disorders scheduled for September 24, 2026.
