CES 2026: Eli launches first instant testosterone test with real-time saliva tracking
Eli Health has launched the world’s first instant saliva-based testosterone test, at CES 2026, and opened pre-orders for a new progesterone test. Both expand the company’s Hormometer platform, turning a smartphone into a real-time hormone dashboard.
Eli adds testosterone and progesterone to its real-time hormone tracker
Eli Health is building momentum after the launch of its instant cortisol test last year. This time around it’s testosterone and progesterone joining the lineup. The company’s goal is simple but ambitious: to give people real-time access to hormone data that’s historically been slow, inconvenient and tied to clinics.
The new testosterone test can be done with saliva, takes just a few minutes, and sends results straight to the user’s phone. That’s a big shift from traditional lab testing, which only offers a one-time snapshot. Testosterone doesn’t stay constant. It shifts with stress, sleep, training and even diet. With Eli’s app and testing system, those patterns become visible and trackable in daily life.
Eli says its saliva-based approach focuses on free testosterone, which is the biologically active form. This is the one most closely linked to energy, libido, strength, motivation, as well as mood in both men and women. But it’s often missing from standard blood panels or only tested occasionally.
Progesterone tracking catches up with the times
The second product Eli is bringing to market is its saliva-based progesterone test. This one is aimed at solving a well-known gap in women’s health. Progesterone has always been tricky to monitor. It fluctuates quickly, requires well-timed blood draws to interpret correctly, and is usually treated as a fertility-specific hormone despite its much wider role in sleep, mood, body temperature, and long-term health.
Eli’s progesterone test is built for regular use. Users spit, scan, and get results in minutes – then watch how the numbers shift over time inside the Eli app. That ongoing visibility could be useful across cycle tracking, perimenopause transitions or just better understanding how hormones play into how someone feels day to day.
Availability and pricing
The idea of tracking multiple hormones side-by-side is where things get interesting. Cortisol, testosterone, and progesterone don’t operate in isolation. Cortisol in particular can suppress the other two. That means understanding one signal in a vacuum isn’t enough. By combining real-time data across all three, Eli is trying to show how stress, sleep, training, and recovery intersect with endocrine signals.
Third-party validation studies suggest the platform tracks with over 90% accuracy against lab standards. What’s different here isn’t just speed. It’s the ability to see the full picture in context.
The new testosterone and progesterone tests are now available for pre-order on Eli’s website. Shipping is expected in Q1 2026. Each test starts at $8.25 and works with Eli’s app, which guides users through measurement and interpretation. The existing cortisol test is already available in the US and Canada, with both one-off and subscription options.
