Function
Function gives you access to 160+ yearly lab tests—5x more than a typical annual physical—covering everything from heart, hormones, thyroid, liver, kidneys, heavy metals, nutrients, inflammation, and more, plus actionable insights from top doctors.
You also get member pricing on MRI and CTs that scan for signs of cancer and 100s of other conditions.
All results are stored in one place, making it easy to spot trends, track progress, and take action.
We curate featured partners that share our commitment to true medicine. When you buy through Truemed links, we may earn a commission.
