Labs as instruments, not identity
Repeat out-of-range values before you rebuild your identity around a number.
What Functional Psychiatry & Lab Testing actually includes
TSH in psychiatric evaluation is common because hypothyroidism mimics mood/cognitive complaints.
Root cause psych labs still require a root-cause differential, not a shopping cart.
Clinical FAQ
Do you treat based on Instagram optimal ranges?
No. We use clinical context.
Crisis?
988/ER, not a draw center.
Can I refuse?
Yes.
Can I draw near Lighthouse Point?
Usually yes.
Thyroid?
TSH/free T4 when indicated.
Telehealth results?
If you are in Florida.
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.

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.
