Say hello to the freedom of knowing exactly what’s going on with your weight from the inside out.

Since your metabolic health impacts everything—weight, hormones, energy, brain health, everything—unlocking its mysteries can kickstart a whole new chapter in your health journey. 

Now you can start building a routine around what will actually make a difference for your unique biology.

What we test
  • Fasting Insulin 
  • Fasting Glucose
  • % Hemoglobin A1C (HbA1c)
  • Thyroid Stimulating Hormone (TSH)
  • Vitamin B12
  • Triglycerides
  • HDL Cholesterol
  • LDL Cholesterol

Receive a detailed breakdown of each marker and what they mean inside our SoWell portal.

Is this test for me?

Here are a few symptoms that are linked to metabolic dysfunction:

  • Weight gain 
  • Increased hunger
  • Depression
  • Mood changes
  • Fatigue
  • Brain fog 
  • Irregular periods
  • Infertility 

If you can relate to any of the above, it’s probably a good idea to get your metabolic markers tested. Don’t worry, we’ve got you!

What's included

Everything you need to test at home:

  • Easy instructions
  • Blood sample collection kit
  • Prepaid shipping envelope
  • Personalized explanation of results
  • Custom next steps
  • Access to online resources

Uncover the full picture of your metabolic health and what to do about it

Blood Sugar

Your blood sugar levels are closely tied to energy, hunger signals, and fat storage in your body. When your blood sugar is chronically too high, it can lead to insulin resistance and metabolic dysfunction, which makes it very challenging to lose weight.


Testing cholesterol gives you an even deeper look into your metabolic health. If you have high triglycerides paired with high LDL (bad cholesterol) and low HDL (good cholesterol), it’s a sign of metabolic dysfunction.


Your thyroid helps your body set its basal metabolic rate (BMR) and plays a role in your body composition—how much fat vs. muscle you hold onto.

B12 Deficiency

Your body needs vitamin B12 to convert food into energy and help you maintain lean muscle mass. A deficiency in B12 can disrupt your thyroid function and energy, making you feel sluggish.

Fasting Insulin

This kit is the first and only at-home test that identifies insulin resistance early on and gives you the next steps to get your levels under control.

Fasting Glucose

A fasting glucose test measures the amount of glucose, or sugar, in blood after an overnight fast. While glucose is the body’s main energy source, too much or too little glucose can cause big issues.

% Hemoglobin A1C

A Hemoglobin A1C (HbA1c) test evaluates average blood sugar levels over the past 2-3 months. It is used as a screening tool for type 2 diabetes and its precursor, prediabetes.

Thyroid Stimulating Hormone (TSH)

Thyroid Stimulating Hormone (TSH) signals the thyroid to make two main hormones that are delivered to the body, T3 and T4. Measuring TSH gives us an idea of your thyroid health.

Vitamin B12

Vitamin B12 is an essential nutrient that our body needs, but does not produce. A vitamin B12 deficiency can make you fatigued and can be a sign of inadequate or improper vitamin absorption.


When fasting triglycerides are elevated, it can often be a sign that the body is having a difficult time processing carbohydrates and maintaining metabolic health.

HDL Cholesterol

HDL is often called "good" cholesterol because it prevents the buildup of plaque in the arteries. Unlike with triglycerides or LDL, you want your HDL number to be high.

LDL Cholesterol

LDL is often called "bad" cholesterol, because it carries cholesterol to the arteries, potentially leading to plaque build-up. High LDL levels put you at risk for heart disease.


AKA the Homeostatic Model Assessment for Insulin Resistance. This validated tool determines your risk for insulin resistance, even before it is evident in more traditional screening measures like HbA1C.

Simply send in your blood sample, and the lab will process your results in 2-5 days!

    I like the practice and versatility of doing my test at home, but I'm worried about the accuracy. I keep track of my glucose, and on the day of the test, using the exact same drop of blood in my test at home I get 110mg/dl but on my results I get 70mg/dl, it's a 36% lower. With my wife, the difference was big too, 98mg/dl at home and 61 in the biology kit.

    The process was not difficult and was relatively fast. The issue is knowing what to do with the information.
