Ash Wellness: What You Should Know

Ash fits an organization that is already large enough to run a population testing program: a health plan closing HEDIS care gaps, a public health department sending out STI kits, or a digital health company that wants to trigger kits from its own app by API. It is kit-first, with more at-home sample types than most vendors (Tasso and dried blood spot blood, urine, stool, saliva and multi-site swabs), and it runs patient outreach and abnormal-result follow-up through its provider-of-record partners. It also added in-person testing through a nationwide lab partner in 2025.

Karpa fits a smaller business without a medical license that wants to sell lab tests to its own customers under its own brand, with a storefront included (or a white-label checkout on its own site, or an API), its own retail prices, and payments settling to its own Stripe account. A licensed provider in Karpa's network orders every test, and customers draw at a Labcorp patient service center today, walk-in or booked. Karpa's branded at-home kits, including white-labeled Tasso devices above a minimum order, do not launch until December 1, 2026, so a buyer who needs at-home kits now, or sample types beyond blood, will find Ash further along. Karpa covers 47 states plus DC (not Hawaii, Maine or North Dakota) and lets a business add TRT, HRT, GLP-1 or peptide programs under the same brand later.

Ash Wellness or Karpa: Who Each Fits

When Ash Wellness fits

Ash Wellness is the stronger fit for a health plan, public health program or established digital health company that wants a branded at-home kit program with many sample types, API ordering and results, and patient outreach run by the vendor.

Ash Wellness, Inc. is a New York company that markets itself as Ash, an at-home health testing platform. It began selling at-home STI kits directly to consumers, then moved to selling kits and programs to organizations. Today it runs white label programs where the kit, instructions, outreach messages and patient portal carry the client's brand, while Ash handles fulfillment, lab processing through 10+ CLIA/CAP partner labs, and clinical oversight through provider-of-record partners. Clients connect through a REST API or a Client Portal with real-time reporting. Ash offers 100+ biomarkers validated for self-collection, HEDIS gap-closure programs for health plans, English and Spanish materials, and since 2025 an in-person testing option through a nationwide lab partner.

When Karpa Health fits

Karpa is the stronger fit for a business without a medical license that wants to sell Labcorp testing under its own brand, set its own prices, and add prescription programs later.

Karpa Health runs an automated lab storefront under the partner's brand: patient intake, a licensed provider's order, Labcorp testing, and the Labcorp report in a branded patient portal. The partner sets prices, payments settle to the partner's own Stripe account, and a partner portal shows revenue, orders, lab results, custom panels and discount codes. No website build, medical license or LegitScript certification is needed for labs-only. Instead of the ready-made storefront, a business can add a white-label checkout and patient portal to its own website, or connect lab ordering to its own app or platform through Karpa's API. See how Karpa's lab storefront works.

Karpa's limitations

Branded at-home kits launch December 1, 2026; until then customers give samples at a Labcorp patient service center.
Labs-only storefront pricing is shared on a call rather than published.
Covers 47 states plus Washington DC; not available in Hawaii, Maine or North Dakota, where Labcorp has no patient service center.
Labcorp tests only: no specialty kit tests such as DUTCH or Genova.
Results are not reviewed by a provider by default; a provider reviews them only when the customer books a TRT or HRT consult.
Karpa's provider network orders every test, so a practice cannot order under its own clinicians' license.
