I’ve used Function Health for two years now. The first two appointments were longer because they needed to understand how the blood draw would go. However, the last three have been quick and they provide a lot of insight. The information provided is clear and actionable and it’s great being able to easily track trends. Their customer service is great, and if I book a duplicate test they are quick to note it and provide a refund. All in all, it’s been a great experience and it’s pretty much the same price as doing blood draws at a doctor’s office with my insurance and copay. So maybe $100 more but way more test.
