WHOOP Advanced Labs

Plan	Price	Unit	As stated on the page
1 test / year	$199	billed annually	$199 per year shown on shop.whoop.com (confirmed 2026-10-18).
2 tests / year	$349	billed annually	$175 per test. Not confirmed on an official page from this box; re-check.
4 tests / year	$599	billed annually	Not confirmed on an official page from this box; re-check.
6 tests / year	$899	billed annually	Not confirmed on an official page from this box; re-check.

RE-CHECK STILL NEEDED (2026-10-18). Confirmed from an official WHOOP page: shop.whoop.com's Comprehensive Health Panel Subscription page shows '1 test $199 per year' (75 biomarkers). The 2, 4 and 6-test prices ($349, $599, $899) are not visible in that page's static content; they come from a search-engine copy of whoop.com/us/en/advanced-labs/ and match WHOOP's own launch press release ($199 / $349 / $599) and Fierce Healthcare (Aug 18 2026, incl. $899). whoop.com itself returns a Cloudflare challenge (HTTP 403) to this box, which was not bypassed. The official page now says 'No subscription or wearable required' and also lists specialized panels; WHOOP's gift page says NY, NJ and RI tests carry an extra state-required fee of $141 per test.
