Company profile

researched Aug 2026

Ash operates an end-to-end at-home health testing platform that organizations integrate to run their own branded testing programs. A single integration gives clients access to branded program design, patient support and engagement, a US lab and provider network, technology and API integration, and program management and reporting. Clients can build white-label experiences spanning communications, the test kit itself, and the patient portal, with bilingual (English and Spanish) capabilities and a multilingual live support center.

The company serves three stated customer segments: health plans, digital health companies, and public health organizations. Testing solutions cover closing care gaps and HEDIS measures for preventive screening, cancer screenings, chronic conditions, infectious disease, environmental health (allergen panels), and hormonal health. Specific panels include a fecal immunochemical colorectal cancer screening test (COL HEDIS measure), an HPV test (CCS measure), a kidney function panel (KED measure), an HbA1c diabetes test (GSD measure), and a common STI panel for chlamydia and gonorrhea (CHL measure).

Operationally, a patient orders a kit through the client's platform, the order reaches Ash via API, and Ash picks, packs and ships the kit within 24 hours. Patients self-collect at home and return samples to Ash's network of CLIA-/CAP-certified labs; results are returned to the client platform by API, with clinician calls from Ash's provider network for critical results. Ash states it handles Provider of Record requirements and follow-up for abnormal results, with providers licensed in all 50 states, and also offers in-person lab capabilities.

Business model

Ash sells its testing platform to organizations rather than directly to consumers, packaging kit fulfillment, lab processing, patient engagement, clinical follow-up and reporting into a white-label program that clients embed in their own brand and technology stack via API.

Ash contracts with client organizations that pay for customized at-home testing programs covering kit fulfillment, lab processing, patient engagement and clinical follow-up; the site frames the offering as a way for digital health clients to drive revenue and for health plans to improve quality measures.

Traction

Ash reports more than 4 million biomarkers processed across the US, 1 million custom test kits shipped, 500,000 kits shipped to prevent infectious disease, daily kit fulfillment capacity of over 3,000 kits, 10+ partner labs serving all 50 states, and 100+ biomarkers/panels available. In public health programs it reports reaching 50% of patients who had not been tested for STIs in a year or longer. Named clients and partners referenced include Give Legacy, Noom, Caraway and Innovaccer.

Latest developments

In July 2026 Ash added health care industry veteran Jon Stout to its board of directors and named Matt Benton, a health tech finance leader, as Chief Financial Officer, described as strengthening leadership as the company scales Medicare Advantage care gap closure programs. Other recent activity includes an AI gap-closure collaboration with Innovaccer and GLP-1 testing work with Noom.

▸Full profile — market position, technology, go-to-market, geography

Market position

Ash describes itself as a leading at-home health testing platform and an expert in bespoke home health testing program design, and was named Best Brand and Marketing at TCA's TheHealthies awards.

Ash positions itself against traditional single-lab providers on breadth and experience: a network of 10+ labs versus a single lab, end-to-end white labeling versus none, 2-3 day turnaround versus slower traditional processing, bilingual Spanish/English platform and support, and customized results narratives with referrals rather than a standard lab result. It also cites 2x faster fulfillment and results turnaround and 2.4x higher patient engagement rates compared with competitors, and 50% lower sample rejection rates.

Technology

A tech-enabled platform with API integration into client systems and lab APIs, a patient portal for kit tracking and results with tailored next steps, and a real-time client reporting portal for program management. Testing methods include dried blood spot card collection and other at-home collection methods, processed across a network of 10+ CLIA-/CAP-certified labs.

Go-to-market

Direct enterprise sales with demo requests and contact forms on the website, supported by a dedicated client success team that works with clients from program design through onboarding, launch and ongoing management; content marketing via an extensive blog and named partnerships with digital health companies.

Health plans (member care gap closure, Star Ratings and HEDIS measures, including Medicare Advantage programs), digital health companies (white-label testing to support acquisition, retention and end-to-end care), and public health organizations serving hard-to-reach populations.
