"Normal" isn't the same as optimal.
A routine checkup looks at a handful of markers and asks whether anything is wrong. Functional testing looks at the whole picture and asks how you can feel your best.

What is The Root Co.?
The Root Co. is Replenish's sister company for functional lab testing, founded by Britt Driggers, PA-C. It offers a yearly deep-dive panel with 100+ markers, specialty tests, and a personal written summary of your results.
Why get functional lab testing every year?
A routine checkup looks at a handful of markers to see if anything is wrong. A yearly functional panel looks at 100+ markers across nine body systems, so you can see how your health is trending and make small changes early, with a plan written for you.
What's included in the Yearly Panel?
100+ markers across nine body systems, including blood and immunity, heart health and inflammation, thyroid, a full hormone panel, nutrients, kidney, liver and metabolic health, biological age and heavy metals. It's $389 a year, or $469 with a mid-year check-in, HSA/FSA eligible, with your lab draw near you included.
Which tests are common at Replenish?
Micronutrient testing ($499) to match your iV to your needs, the Vitamin D Panel ($99) required before vitamin D injections, and High-Dose Vitamin C Screening ($109) required before any vitamin C iV over 20 grams.
Why do I need labs before high-dose vitamin C?
Medical guidelines call for a CBC, CMP and G6PD screening before any vitamin C iV over 20 grams. G6PD deficiency in particular can make high doses unsafe. Email hello@replenishiv.com and our clinical team will help you get started.
Where are my labs drawn, and how long do results take?
Your Yearly and Mid-Year panels include your lab draw at a facility near you, or a mobile phlebotomist can come to you for $99. Most specialty tests can also be drawn at a facility near you for free, while some require a special kit. When we send your order form, we'll tell you exactly how to collect your sample, and a mobile phlebotomist is available if you need one. Yearly panel results arrive within 2 to 3 weeks. Some specialty tests take longer; the micronutrient test typically takes 4 to 5 weeks. Every result comes with a detailed written summary.
