Comprehensive Hormone Testing Panel

Comprehensive hormone testing panels at Radiant Health SF covering adrenal, reproductive, and thyroid hormones via serum, saliva, and urine collection methods. Panels assess cortisol, melatonin, estrogen, progesterone, testosterone, DHEA, and thyroid markers alongside vitamins, neurotransmitters, and metabolites. Ordered through specialty labs including ZRT, Meridian Valley, and Genova Diagnostics. Results reviewed by a naturopathic physician with expertise in functional endocrinology and BHRT.

Radiant Health SF offers one of the most thorough hormone testing workups available through a naturopathic clinical setting in San Francisco, drawing on multiple specialty laboratory partners to tailor the testing method and marker selection to each patient's presentation. The clinic employs serum, saliva, and dried urine testing depending on the hormones of interest and the clinical question. Saliva testing is used for diurnal cortisol mapping — capturing the cortisol awakening response (CAR) and the natural cortisol slope across four or more collection points in a single day — alongside salivary sex hormones when tissue bioavailability rather than total serum levels is the primary concern. Dried urine testing via ZRT Laboratory's DUTCH-equivalent panel or Meridian Valley captures a broader metabolite profile, showing not only total estrogen and progesterone but also their primary downstream metabolites such as 2-OHE1, 4-OHE1, and 16-OHE1 (estrogen hydroxylation pathway), as well as cortisol metabolite load, DHEA-S, and melatonin. This metabolite-level view is clinically important for patients with hormone-sensitive conditions, where the ratio of protective versus proliferative estrogen metabolites is a relevant consideration. Serum panels ordered via Boston Heart or Ulta Labs supplement the urinary/salivary data with total and free testosterone, SHBG, thyroid antibodies (TPO-Ab, TG-Ab), free T3, free T4, reverse T3, TSH, and insulin. Vitamins, neurotransmitters (dopamine, serotonin, norepinephrine precursors via urine), and organic acids may be included in a comprehensive workup. Dr Kristy Vermeulen and Dr Nazanin Safaei review results in the context of symptoms, health history, and goals — with particular expertise in functional hypothyroidism, adrenal fatigue patterns, perimenopause, andropause, and BHRT optimisation.
