Progesterone (Pg) Saliva Test
Progesterone (Pg) Saliva Test
*PLEASE NOTE: Residents in California, Maryland, and New York must receive a signature from a licensed care provider in their state before ordering tests. Patients will need a laboratory order from a healthcare provider requesting the tests that they purchased – this is usually a script that looks similar to a prescription fill. It should contain the provider’s name, signature, contact information, and the ZRT tests ordered. This will be returned with the blood/urine/saliva sample(s).
Home progesterone saliva test kit. Includes collection tube and prepaid envelope for mailing sample back to lab. Results are emailed to the patient within a few days after receipt of the sample.
Why saliva? Estrogens (estrone, estradiol and estriol), progesterone, testosterone, DHEA-S and cortisol are routinely measured in saliva at ZRT. Steroid hormones in the bloodstream are mostly (95-99%) bound to carrier proteins (hormone-binding globulins, albumin), and in this form they are unavailable to target tissues. Only the unbound fraction freely diffuses into tissues, including the salivary gland. Hormone levels in saliva therefore represent the quantity of the hormone that is currently available to target tissues and actively exerting specific effects on the body. Because of this, salivary hormone levels often relate to specific symptoms of hormone excesses or deficiencies. Research at ZRT has demonstrated clear correlations between salivary hormone levels and reported symptoms. The rationale for and clinical utility of saliva testing is well documented.
