Junction (Vital) vs Karpa: White Label Lab Testing Comparison (2026)

Junction pricing, as of November 9, 2026: Lab testing is part of the custom-priced Enterprise plan, billed annually; test prices are not published, and Junction says there are no upcharges on the tests themselves. The Launch plan is $300/month for wearables only (up to 500 connected users). At-home kits have a stated 250-kit minimum order, with smaller quantities on request. 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 Junction, based on Junction's own public materials as of November 9, 2026. Karpa competes with Junction, so weigh it accordingly. Pros: Flexible ordering: Junction's physician network, the customer's own physicians, or a hybrid; Four collection methods through one API: at-home kits, mobile phlebotomy, walk-in draws at Quest, Labcorp and BioReference, and on-site collection. Cons: API infrastructure: the customer builds its own app, checkout and patient experience, which needs engineering resources; Lab testing is only on the Enterprise plan, which is priced per customer and billed annually. The full list, with a source for each fact, is on this page.

Yes. Vital (tryvital.io) rebranded to Junction on March 11, 2025, the same day it announced an $18M Series A led by Creandum. The product is the same health data and lab testing API, now at junction.com and docs.junction.com.

It can. Junction's docs describe three setups: Junction's physician network orders the test and reviews results, the customer supplies its own ordering physicians, or Junction's network orders and the customer's physicians review results. Junction's network follows up on abnormal results only for orders it handles, and it is always notified of critical results. Junction does not offer physician consults or result interpretation.

Junction is built for teams integrating its API into their own product: its docs describe creating orders, tracking them by webhook and pulling results into the customer's app, plus a dashboard for managing orders. Junction does not describe a ready-made storefront or patient checkout, so the business builds that part.

Businesses comparing lab testing infrastructure also look at platforms that include the storefront and ordering provider, such as Karpa Health, where a licensed provider in Karpa's network orders every test, Labcorp runs it, and the business can sell through a branded storefront, its own website or an API. The right choice depends on whether you have engineers to build the patient experience, which collection methods 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.
