The Portfolio

Five emerging threats. One supplier.

The contemporary drug supply changes faster than most labs can validate a new test. We are the only U.S. supplier offering all five emerging-threat analytes from a single source, configurable into any custom multi-panel a program requires.

01

Fentanyl

The baseline of drug-checking. Trusted lateral flow detection for the most widespread synthetic opioid in the unregulated supply.

Standard offering
02

Xylazine

The veterinary tranquilizer now driving the next wave of overdose presentations. Independent benchmarking against competing strips demonstrates substantially improved sensitivity.

High demand
03

Medetomidine

An emerging veterinary tranquilizer increasingly displacing xylazine in regional markets. Detection across racemic mixtures, validated on authentic field samples.

Standard offering
04

Nitazene

A class of synthetic opioids whose potency can exceed fentanyl by orders of magnitude. U.S.-supplied. Designed to address documented gaps in competing strips, including detection of analogs that incumbent products miss.

Standard offering
05

Benzodiazepines

Detection across the benzodiazepine class, including the designer analogs increasingly found in counterfeit pressed pills.

Custom multi-panels

We configure multi-analyte panels for specific use cases: settlement-fund field deployments, syringe service programs, hospital intake, custodial and corrections settings. Tell us what you need to detect.

Custom build

Beyond Drug Checking

Other diagnostics. Same team.

Drug-checking is our current focus, not the limit of what we do. The lateral-flow chemistry, supply chain, and regulatory work behind the five-analyte portfolio also sits underneath a broader set of diagnostic capabilities developed across thirty years.

Who We Serve

Built for institutional buyers.

Our supply chain, pricing structure, and technical support are designed for the procurement realities of public-sector and large institutional buyers, not consumer retail.

State and county health departments

Procurement against opioid-settlement fund allocations. Bulk pricing, rolling release schedules, training support included.

Service-Disabled Veteran-Owned Small Business (SDVOSB) distributors

A U.S.-based supplier with a vetted partner manufacturing network supporting federal contract vehicles including the Federal Supply Schedule (FSS), Distribution and Pricing Agreement (DAPA), and Electronic Catalog (ECAT). DSG holds an active CAGE Code and is registered in the System for Award Management (SAM).

Harm reduction organizations

Direct supply to syringe service programs, mobile outreach teams, and state-funded harm reduction networks. Hub-pricing for distribution partnerships.

Hospitals and large clinical systems

ED intake, behavioral health, custodial settings. Multi-panel configurations available for specific clinical workflows.

Corrections and reentry programs

Intake testing and reentry support across state and county jurisdictions. Volume-appropriate pricing and packaging.

National and international government

Diagnostic deployments at the national level for the governments of seven countries to date. Temperature-controlled logistics available where required.

Why DSG

What you don't get from anyone else.

Complete five-analyte portfolio from one U.S. supplier

The only U.S. supplier offering all five emerging-threat drug-checking strips from a single source: fentanyl, xylazine, medetomidine, nitazene, and benzodiazepines. Configurable into any custom multi-panel a program requires.

U.S.-based supply with vetted manufacturing partners

We work with established diagnostic manufacturers, including U.S. partners such as Princeton BioMeditech (LifeSign) and U.S.-based assay developers, and validate every lot before it ships. Procurement officers get a domestic point of contact, a domestic supply contract, and firm lead times.

Thirty years of diagnostic depth

The same team that has developed assays for the world's largest pharmaceutical companies, national governments, and the Red Cross. Drug-checking is a continuation of that work, not a pivot away from it.

Federal contracting ready

SAM-registered. CAGE Code assigned by the Defense Logistics Agency. Documentation and contracting infrastructure already in place for federal, state, and county purchasing.

Pricing for institutional volume

Quote structure built for settlement-fund procurement, GPO pull-through, and multi-jurisdiction roll-outs. Not a retail SKU pretending to be a B2B product.

Technical support included

Drug-checking is a moving target. We follow what is appearing in the supply, advise on panel configurations, and support training for frontline staff. In-person and online programs available.

Validated against the community standard

Our QA program is aligned to the published academic lot-testing framework from the Lieberman group at Notre Dame and to the new AOAC standards (SMPR 2025.002 and SP 2025.001) covering benzodiazepines, fentanyl, medetomidine, nitazenes, and xylazine. Read the methodology →

Our Story

Thirty years of building diagnostics that have to work.

Diagnostic Solutions Group has developed custom diagnostic solutions for thirty years. Our work spans complex mass screening for blood banks, individual point-of-care testing, and large-scale global deployments across antibody, molecular, and antigen platforms.

Our partners have included Johnson & Johnson, Pfizer, Novo Nordisk, Abbott Laboratories, Ortho Clinical Diagnostics, and the Red Cross. We have supported national diagnostic deployments for the governments of Nigeria, Côte d'Ivoire, Bangladesh, Liberia, Jamaica, India, and Mali. Our work has reached numerous Broadway productions, hundreds of hospitals and urgent care centers, and a wide range of long-term care facilities.

There is no one-size-fits-all diagnostic. The right answer depends on the pathogen, the venue, the operator, and the workflow. That has been true for performing-arts COVID screening, for in-office differential testing of COVID against influenza, and for dengue screening in rural settings. It is just as true for the harm-reduction work that defines our current focus.

Today the bulk of our development and supply is concentrated on five drug-checking analytes: fentanyl, xylazine, medetomidine, nitazene, and benzodiazepines. We ship them as single-analyte strips or as custom multi-panels assembled to a buyer's specification. We are the only U.S. supplier offering all five from a single source.

Our QA program is aligned to the published academic lot-testing framework from the Lieberman group at Notre Dame and to the AOAC standards released in late 2025 (SMPR 2025.002 and SP 2025.001), the closest thing the harm-reduction strip market has to a community standard. We document and disclose lot QC data with every institutional order. Read the methodology →

Alongside the harm-reduction portfolio we continue to manufacture and ship a rapid antigen test for COVID-19 and influenza A&B for clinic, urgent-care, and turnkey deployment, and a rapid sickle cell screening assay supported by AI-assisted result interpretation, originally developed at a national ministry of health's request as a field-deployable alternative to lab-based hemoglobin electrophoresis.

Our solutions extend beyond the test itself. We provide test interpretation supported by artificial intelligence, AWS-based data management and insights, custom packaging, language translations, custom inserts, and in-person and online training programs.

We are end-to-end supply chain experts, specializing in the import and export of diagnostic tests and reagents. We obtain regulatory approvals, registrations, clearances, and emergency use authorizations. When the product requires it, we provide temperature-controlled logistics.

We are a registered supplier to the United States Government and active in the System for Award Management (SAM). We hold a Commercial and Government Entity (CAGE) Code from the Defense Logistics Agency.
