What Diagnostic Solutions Laboratory does

Diagnostic Solutions Laboratory is a US-based clinical diagnostic laboratory founded in 2015 and headquartered in Alpharetta, Georgia, operating as a private LLC under CEO Tony Hoffman. The company specializes in advanced gastrointestinal and functional medicine testing, built around a quantitative PCR (qPCR) platform that detects and quantifies microbial DNA from stool samples — it self-describes as the only US laboratory exclusively using qPCR for comprehensive stool testing. Its flagship product, the GI-MAP (Gastrointestinal Microbial Assay Plus), is supported by a growing add-on ecosystem including StoolOMX (bile acids and short chain fatty acids), Zonulin (intestinal permeability), Fecal Gluten Peptide, and a Universal Antibiotic Resistance Genes Panel covering 55 resistance genes across 10 antibiotic classes. Complementary products include the CytoDx cytokine response profile (40 cytokines), OMX and OAp organic acids/metabolomics panels, IgG and IgE food/allergy panels, a Fatty Acids Profile, GenomicInsight, a Histamine Clearance Index, and a stool Pathogens Panel. Test turnaround on the GI-MAP is 7-10 business days.

The company sells exclusively through licensed healthcare practitioners (NDs, DOs, MDs, PAs, NPs) primarily in the functional and integrative medicine space, with order entry via an online Practitioner Portal, phone, or email and drop-ship capability directly to patients for qualified tests. Only the GI-MAP and GI-MAP with Zonulin are insurance-billable; the remaining menu is cash-pay with discounted self-pay pricing and a deposit requirement at submission. Geographic coverage is concentrated in the US and Canada, with New York state excluded due to licensure. The company reinforces clinical adoption through DSL Academy, a gated education platform that offers structured courses and a Medical Education Team, plus an extensive content marketing operation (164+ GI-MAP resources including webinars, white papers, and case studies) and active presence at industry events such as IFM APM GI, IDS Integrative Dermatology Symposium, and A4M Longevity Fest. The business is bootstrapped with no disclosed external institutional investment.

Revenue model

1. Clinical Laboratory Testing Services: Diagnostic laboratory testing services for healthcare practitioners. Tests include GI-MAP, CytoDx, StoolOMX, OMX Organic Metabolomics, OAp Organic Acids Profile, IgG Food Explorer, GenomicInsight, and others. Revenue generated through test fees billed to patients/practitioners.
2. Insurance Billing: Laboratory bills insurance companies directly for qualifying tests. Only GI-MAP and GI-MAP with Zonulin are submitted to insurance; all other testing is cash-only. Medicare participation for traditional Medicare. Out-of-network with commercial insurance.
3. Cash Pay/ Self-Pay: Direct patient payment for testing services. Discounted cash pricing available. Deposit required at time of test submission (except Medicare). Payment via check, money order, or major credit card.

Core offering

Diagnostic Solutions Laboratory operates a clinical diagnostic laboratory that performs advanced molecular and functional medicine testing for licensed healthcare practitioners. Its flagship GI-MAP stool test uses proprietary quantitative PCR (qPCR) technology to detect and quantify microbial DNA, complemented by cytokine, metabolomic, food sensitivity, and genomic panels that practitioners order to support personalized treatment protocols for gut, immune, and metabolic conditions.

Product overview

Diagnostic Solutions Laboratory offers a comprehensive portfolio of clinical diagnostic tests primarily focused on functional and integrative medicine. The core products include the GI-MAP (comprehensive stool analysis via qPCR technology) and CytoDx (cytokine response profile for immune function). The product architecture follows a platform-plus-modules model where the GI-MAP serves as the primary platform with multiple add-on panels including StoolOMX (bile acids and SCFAs), Zonulin, Fecal Gluten Peptide, and Universal Antibiotic Resistance Genes. Additional standalone products include OMX (Organic Metabolomics), OAp (Organic Acids Profile), IgG Food Explorer, IgE Allergy Explorer, FAp (Fatty Acids Profile), and Histamine Clearance Index. The company also provides practitioner education through DSL Academy. Tests are ordered through licensed healthcare providers and results delivered via the Practitioner Portal.

Direct peers

• Genova Diagnostics: Genova Diagnostics is the dominant US functional medicine lab offering GI Effects (a comprehensive stool analysis directly comparable to GI-MAP) as well as organic acids, hormones, and genomic tests ordered through licensed practitioners - the same practitioner-led, multi-modality model DSL competes in.
• Cyrex Labs: Cyrex Labs sells Array-based food sensitivity, intestinal permeability (zonulin), and autoimmune panels ordered through functional and integrative practitioners - competing head-to-head with DSL's IgG Food Explorer and the GI-MAP Zonulin add-on.
• Precision Analytical (DUTCH): Precision Analytical's DUTCH dried-urine hormone/metabolite panels are ordered by the same functional/integrative clinician base via similar drop-ship and portal workflows, competing for the multi-modality upsell dollars DSL targets.
• Vibrant Wellness: Vibrant Wellness uses multiplex and qPCR-style chemistries to deliver food sensitivity, gut microbiome, and hormone tests through the same practitioner-channel model, directly contesting DSL's qPCR-based functional testing positioning.
• ZRT Laboratory: ZRT Laboratory sells dried-blood-spot and saliva hormone/metabolite tests through functional medicine providers, with overlapping clinician-only ordering, drop-ship kit, and add-on panel model that complements DSL's diagnostics portfolio.
• Doctor's Data: Doctor's Data has long offered comprehensive stool parasitology, culture-based microbiology, and toxic-element testing ordered through integrative and functional medicine practitioners, overlapping directly with DSL's clinician-channel stool testing focus.
• Mosaic Diagnostics (formerly Great Plains Laboratory): Mosaic Diagnostics serves the same functional medicine prescriber base with Organic Acids Test (OAT), GPL-TOX, and stool-based profiles, providing nearly identical collection-and-drop-ship workflows and clinician-targeted education platforms.
• US BioTek: US BioTek provides IgG and IgE food sensitivity panels (160+ antigens) ordered through integrative practitioners, directly competing with DSL's IgG Food Explorer (283 antigens) for the same clinician-driven food sensitivity wallet share.

Broad incumbents

• Labcorp: Labcorp is a national reference lab that processes conventional stool and parasitology testing for hospitals and physician offices and increasingly offers specialty panels; its payer reach and specimen logistics threaten DSL on the insurance-billable side of the menu.
• Quest Diagnostics: Quest Diagnostics is a national reference lab whose broad portfolio includes conventional stool culture and an expanding menu of specialty/functional assays; its scale and in-network payer contracts pressure niche labs like DSL on insurance-billable commodity stool testing.
