The Sweatprint™ Test

Measure how you actually sweat

The Sweatprint™ Test is a non-invasive sweat analysis that captures the two numbers your formula is built on: sweat sodium concentration and sweat rate.

What the test involves

During a normal training effort, sweat is collected from patches on the skin and analyzed for sodium concentration. Your sweat rate is calculated from body-weight change and fluid intake over the session. It’s painless and doesn’t require blood. TODO: confirm exact in-house methodology and equipment.

In-person vs. at-home

In-person testing at a partner site gives our team direct control over collection conditions. The at-home kit trades some of that control for convenience and lets you test under your own typical training conditions. TODO: finalize at-home kit availability and partner locations.

What you’ll learn

  • Your sweat sodium concentration (mg/L)
  • Your sweat rate (L/hr) under real training conditions
  • Your calculated hourly sodium and fluid losses
  • Which optional additives your profile supports

How to prep

  • Come to your session hydrated and normally fueled — don't fast or dehydrate.
  • Bring the kit and clothing you'd use for a typical training session.
  • Avoid unusually salty meals in the 24 hours before, if possible. TODO: confirm prep protocol.

Price: TODO — set Sweatprint™ Test pricing.
