Product Code: S-125

This profile measures 7 key hormones in saliva using the highly precise LC-MS method, available for both females and males: (S-125)

  • Steroid hormones: Estradiol (E2), Estrone (E1), Estriol (E3), Progesterone (Pg), Testosterone (T)
  • Adrenal & stress hormones: DHEA-S, Cortisol (C)

Why it matters: LC-MS provides a detailed view of the full steroid hormone cascade, offering deeper insight into clinical issues that may arise from insufficient or excessive hormone therapies.

ZRT LCMS Saliva Steroid & Steroid Synthesis Inhibitor Profile (S-125)

ZRT Laboratory now offers a comprehensive LC-MS/MS saliva assay that measures the levels of 7 endogenous steroid hormones, including estrogens, progestogens, and androgens. The LC-MS/MS assay expands beyond the 5-steroid panel of parent hormones (estradiol, progesterone, testosterone, DHEAS, and cortisol) currently tested by immunoassay (IA) at ZRT Laboratory.

LC-MS has some advantages over EIA and vice versa. LC-MS is more sensitive at very low levels, which can be helpful when hormones are in very low concentrations. LC-MS may also offer advantages when high-dose hormones are being used topically, which may cause cross-reactions with antibody testing.

It is also a great test to determine how different types of hormones and their administration routes (e.g., oral, topical, transdermal patch, IM/SC injections, pellet, vaginal) affect their bioavailable (saliva) levels.

The LC-MS test is also a more useful tool for understanding what pathways precursor hormone therapies (e.g., pregnenolone, DHEA, progesterone, and testosterone) take to become active estrogens, progestogens, and androgens.

All Tests Included:

Estrogens: Estradiol (E2), Estriol (E3), Estrone (E1), Progesterone (Pg), Testosterone (T), DHEA-S (DS), and Cortisol (C).
