Spot Dx vs Karpa: White Label Lab Testing Comparison (2026)

Spot Dx pricing, as of November 9, 2026: Not publicly listed; Spot states no upfront costs and simple, usage-based pricing. For comparison, Karpa Health also shares its labs-only storefront pricing on a call rather than publishing it; on Karpa the business sets its own retail price for each lab order, payments settle to its own Stripe account, and each order carries a $6 collection fee.

This is Karpa Health's review of Spot Dx, based on Spot Dx's own public materials as of November 9, 2026. Karpa competes with Spot Dx, so weigh it accordingly. Pros: Fully branded kits, packaging, portals and email and SMS shipping updates; Ready integrations for Shopify (set up from Spot's portal), WooCommerce (a code snippet) and Wix or Squarespace (a custom endpoint Spot sets up). Cons: Built to plug into a store or app the business already runs; a business without one would need to set it up first; Partner labs are not named publicly. The full list, with a source for each fact, is on this page.

Spot Dx operates as Spot Health, a Cincinnati company founded in 2021 that went through Y Combinator's Winter 2022 batch. It describes its service as HIPAA compliant, uses its own physician network licensed in all 50 states for doctor's orders, sends samples to partner labs it does not name, and publishes its API documentation at docs.spotdx.com.

Yes. Spot's docs say a Shopify integration is managed from Spot's management portal: you map Shopify SKUs to Spot kit types and add a webhook on the order payment event. WooCommerce stores add a code snippet that sends orders to Spot's API, and for Wix and Squarespace Spot sets up a custom webhook endpoint.

Spot says it built its own physician network licensed in all 50 states and handles the doctor's order where a state requires one, so the brand does not need its own physician. Requisition tools in its API are off by default and are meant for brands that manufacture their own collection kits.

Businesses comparing white label lab testing also look at platforms that include the storefront and checkout, such as Karpa Health, where a licensed provider orders each test, Labcorp runs it at a patient service center draw, and branded at-home kits launch December 1, 2026. The right choice depends on whether you already run an online store, which sample types you need, and whether you want prescription programs later.

No. A licensed provider in Karpa's independent network orders every test, so the business never orders or interprets labs. Labs-only needs no LegitScript certification, and Karpa's lab testing covers 47 states plus Washington DC.

Three ways: use Karpa's white-label lab storefront under your brand, add Karpa's lab ordering checkout and patient portal to your own website, or connect your own app or platform through Karpa's API. In each, a licensed provider in Karpa's network orders the test, Labcorp runs it, and payments settle to your own Stripe account.

They walk in or book a time at a Labcorp patient service center. Branded at-home kits launch December 1, 2026, and from then, above a minimum order quantity, Tasso at-home collection devices can be white-labeled under your brand and sold as a subscription, such as a retest every quarter.
