SiPhox Health vs Karpa: White Label Lab Testing Comparison (2026)

SiPhox Health pricing, as of November 8, 2026: Not publicly listed; partners buy kits at wholesale and resell at retail, with commercial terms set after program definition. SiPhox's articles state a 30-kit minimum to start, volume discounts from 100 kits, and 500+ kits for full white label and custom panels. Consumer pricing, for context, starts at $124 per test plus shipping on a monthly, quarterly or 6-month plan. 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.

SiPhox Health is a venture-backed company founded in 2020 by MIT scientists, a Y Combinator alum, and announced $27M in funding led by Intel Capital and Khosla Ventures in July 2023. Its site says samples are processed by CLIA-certified, CAP-accredited third-party labs. It describes its service as wellness-only and not diagnostic.

Yes. Its Partner Program offers co-branding and gray label at lower volumes and complete white labeling of the kit box, inserts, registration, notifications and results with commitments of 500+ kits. Partners manage orders in the SiPhox Health Portal or through a REST API.

SiPhox says requisitions come from its own physician network, so partners do not need to be medical providers. It recommends HIPAA training for partner staff who handle medical reports.

Businesses comparing white label lab testing also look at platforms that order through a provider network and offer lab draw-site collection, such as Karpa Health, which pairs Labcorp patient service centers with branded at-home kits launching December 1, 2026. The right choice depends on collection method, whether you want to buy kits upfront or sell through a storefront, and whether you need a telehealth path.

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.
