What we will not order
Abnormal TSH can mimic depression. That is why we check — not because every mood is endocrine.
Functional Psychiatry & Lab Testing for Lighthouse Point patients
Root cause psych labs still require a root-cause differential, not a shopping cart.
Iron deficiency brain fog is a medical problem we measure.
Protocol elements we do not skip
Fasting when lipids/glucose needed.
Ferritin with context of inflammation.
Hypothesis in the note before the order.
Morning T for men.
Indications and differentials
When a mill already drew chaos and we need clean timed labs.

Clinical FAQ
Adrenal fatigue?
Not a diagnosis we sell.
Do labs replace a psychiatric diagnosis?
No.
Telehealth results?
If you are in Florida.
Who interprets?
Dr. Dorothy Chatelier, DNP, FNP-BC, PMHNP-BC.
Hormones?
Timed, not pellet bait.
Genetic privacy?
We treat it as sensitive data.
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.

No fasting instructions, garbage lipids, dramatic interpretation.
