Hollywood interpretation plus local phlebotomy is the usual pattern.
Clinical scope of Functional Psychiatry & Lab Testing in Broward County
Thyroid mood testing is TSH with free T4 when indicated — not a T3 shopping list by default.
hs-CRP is nonspecific. We do not build a cult around it.
Clinical FAQ
Crisis?
988/ER, not a draw center.
Do you treat based on Instagram optimal ranges?
No. We use clinical context.
Iron?
Ferritin when the story fits.
Hormones?
Timed, not pellet bait.
Office for interpretation?
32 min from Lighthouse Point if in-person.
Who interprets?
Dr. Dorothy Chatelier, DNP, FNP-BC, PMHNP-BC.
Do you offer pharmacogenetic testing?
Yes. We offer pharmacogenetic (GeneSight) testing to determine which psychiatric medications are most likely to be effective for your specific genetic makeup, reducing trial-and-error in medication selection.
What makes your evaluations comprehensive?
Our initial evaluations last 60-90 minutes and include clinical assessment, review of functional lab options, hormone screening discussion, and a personalized treatment plan — not a 15-minute med check.
In-office versus Florida telehealth

Credentials and method
Florida telehealth for Functional Psychiatry & Lab Testing requires the patient to be physically in Florida at the time of the visit. Crossing a state line mid-treatment can pause prescribing until licensure allows.
Functional Psychiatry & Lab Testing at Peace & Heart Wellness is directed by Dr. Dorothy Chatelier, DNP, FNP-BC, PMHNP-BC, a Florida-licensed psychiatric mental health nurse practitioner with more than a decade of hormone-informed psychiatric practice. Care is hormone-informed and lab-aware rather than checklist-only.
GeneSight pharmacogenetic testing is available when prior antidepressant trials failed or side effects were limiting. Results are probabilistic, not deterministic.

Florida telehealth psychiatry is available to established and new patients located in Florida at the time of the visit, subject to licensure and clinical appropriateness.
