Functionhealth

Functionhealth is a subscription-based lab testing service that gives you a comprehensive blood test twice a year. For $365 per year, you get over 160 lab tests that screen for more than 1,000 conditions — from heart disease and diabetes to thyroid disorders and nutrient deficiencies. You schedule your blood draw at any of the 2,000+ Quest Diagnostics locations across the US, and results come back in a few days.

The service stands out because of its doctor-reviewed interpretations. Instead of staring at a raw list of numbers, you get clear explanations of what each result means, written by physicians and backed by thousands of hours of research. Functionhealth also tracks your data over time, so you can spot trends — like rising blood sugar or dropping vitamin levels — before they become serious. You can order additional MRI and CT scans through the platform as well, and the program includes a follow-up plan that encourages you to take action and retest.

This service is for anyone who wants to be proactive about their health. It’s especially useful for people with family histories of chronic conditions, those who haven’t had a physical in a while, or anyone who wants a detailed snapshot of their body's inner workings. The cost works out to about $1 per day, and it’s HSA/FSA eligible. It’s a simple, straightforward way to know what’s going on inside your body every year.
