Saliva testing is a non-invasive collection method where patients collect their saliva in plastic tubes in order to measure hormones like cortisol, estrogens, progesterone, and androgens. This non-invasive saliva collection is ideal for patients because it allows them to collect their sample in the privacy of their home or office.
 
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.
