Comprehensive Hormone Testing Panel

Comprehensive hormone testing panels at Radiant Health SF covering adrenal, reproductive, and thyroid hormones via serum, saliva, and dried urine collection methods. Panels assess cortisol rhythms, melatonin, estrogen, progesterone, testosterone, DHEA, and thyroid markers including free T3, free T4, TSH, and antibodies. All results are reviewed by a naturopathic physician with expertise in functional endocrinology and BHRT.

Radiant Health SF provides one of the most thorough hormone testing workups available through a naturopathic practice in San Francisco, drawing on multiple specialty laboratory partners to tailor the testing method and marker selection to each patient's clinical picture. The clinic uses serum, saliva, and dried urine testing depending on the hormones being evaluated and the questions being asked. Saliva testing is used for diurnal cortisol mapping — capturing the cortisol awakening response and the natural cortisol curve across four or more collection points throughout a single day — alongside salivary sex hormones when tissue bioavailability is more relevant than total serum concentration. Dried urine testing via ZRT Laboratory or Meridian Valley captures a broad 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), cortisol metabolite load, DHEA-S, and melatonin. This metabolite-level view may be clinically meaningful for patients with hormone-sensitive presentations where the balance of estrogen metabolites is a relevant consideration. Serum panels ordered via Boston Heart or Ulta Labs supplement urinary and salivary data with total and free testosterone, SHBG, thyroid antibodies (TPO-Ab, TG-Ab), free T3, free T4, reverse T3, TSH, and fasting insulin. Vitamins, neurotransmitter precursors, and organic acids may be incorporated into more comprehensive workups. Dr Kristy Vermeulen and Dr Nazanin Safaei review results in the context of symptoms, health history, and goals — with particular experience in functional thyroid support, adrenal patterns, perimenopause, andropause, low libido, and BHRT protocol optimisation.
