Saliva testing is used for measuring hormones like cortisol, estrogen and testosterone, and its non-invasive collection asks patients to spit into a plastic tube. This sampling method allows patients to collect saliva at home at specific times, which is important for accurately measuring hormone levels.
Why do we test hormones in saliva? Steroid hormones in the bloodstream are 95-99% bound to carrier proteins, and in this form are unavailable to target tissues. Saliva testing measures the amount of hormone available to target tissues ? the bioavailable amount. For this reason, saliva testing better relates to specific symptoms of excess or deficiency, and is a good option for monitoring hormone therapy.
ZRT is one of the first labs to measure hormones in saliva, and helped establish the method that made saliva hormone testing commercially viable for health care providers and patients around the globe.
Dried blood spot is a form of collection where patients place blood drops on a filter card after a finger prick with a lancet. Once dry, blood spot cards are extremely stable for shipment and storage, and the dried blood format offers excellent correlation with serum tests.
Blood spot is ideal for measuring hormones and other analytes such as insulin, blood lipids, Vitamin D, thyroid hormones, and elements like lead and magnesium. It offers distinct advantages over serum because it eliminates the need for a blood draw ? saving patients time and money.
ZRT developed the science for accurately measuring hormones in dried blood spot and is currently one of the only labs to offer this method commercially.
ZRT's convenient blood spot collection eliminates blood draw needles, blood draw fees and the need to see a phlebotomist. Patients can collect their sample at home at the time that suits them. Research also shows that blood spot is more accurate than serum for measuring blood hormone levels in patients supplementing topically.
