Our Science

You can learn a lot from a few drops of saliva.

Eli combines elements of immunoassays and microfluidics to detect hormones in saliva, bringing you a non-invasive method to test and monitor hormones conveniently from your own home.

No finger pricking, no peeing in a cup.

Our Hormones

Let’s start with Estrogen and Progesterone

Despite their classification as ‘female sex hormones’, research has demonstrated that estrogen and progesterone have widespread functions. They impact learning, memory, immunity and vascular function (among many others).

In fact, estrogen and progesterone are present in and have impact on all humans regardless of biological sex (E2), and these impacts translate to ubiquitous effects you can feel physically and mentally throughout your body – and not just when you’re on your cycle.

Given the importance of these hormones in the human body, Eli’s mission is to provide you with data and insights that will equip you to make decisions throughout your life and improve health outcomes overall.

E2 is one of the four main estrogens in the body. It is also the most abundant form of estrogen in premenopausal females. []{Clark, 1992 #864}

E2 plays many functions in [all] human bodies (not just women). Most of us are already familiar with the reproductive functions of E2 in females, which include the development and regulation of the female reproductive system and secondary sex characteristics, but did you know that E2 has important functions in the cardiorespiratory, musculoskeletal, immune, renal, gastrointestinal, and central nervous systems {Rosner, 2013 #847}

Many of us know P4 as the hormone that prepares the endometrium for potential pregnancy after ovulation. Similar to estrogen, research shows that P4 is involved in many more roles throughout the human body.

In addition to its reproductive functions, P4 plays a role in regulating mood, behavior, inflammation, and cognition. Its receptors have been identified in many tissues, including several brain regions, vascular endothelium, the thymus, and the lungs.

General Health

Understand how diet, exercise, and hormones interact.

We are often given well-meaning but generic advice to “eat a well-balanced diet” and “exercise regularly”. But even if we do manage to make changes, it can be hard to quantifiably see how they impact our health. If you’re a data junkie like us, you may be curious about the relationship between your hormones and your health habits.

With the data from Eli, you’ll have a tool that enables you to better manage stress, energy, mood, and other lifestyle decisions that affect your overall health.

Endocrine Conditions

Track patterns to actively manage symptoms and get the care you need.

The endocrine system regulates bodily processes via the body’s signaling molecules: hormones. Endocrine conditions occur when parts of this system don’t work correctly and can be linked to hormone dysregulation or dysfunction.

By using Eli frequently over time, you will be able to see your data to help identify patterns and solve the puzzle of your endocrine system.
