Why should I test in saliva and not in blood? Is saliva testing accurate?
AYUMETRIX uses the most advanced testing technologies and FDA approved kits, which offer accuracy, validity and convenience over conventional blood tests for the following reasons:
Noninvasive (no needles)
More convenient than blood testing for health care provider and patient
Measures the “unbound” biologically active or free hormone levels
Ideal for measuring and accurately monitoring transdermal application of hormones
Optimized for multiple collections any time of day/month, any place
No special processing (eg, centrifugation, ice-packs) prior to shipment
Hormones stable in saliva for weeks
Ideal for evaluating cortisol secretion patterns, and balance and flow of estrogens and progesterone.
Salivary estriol can be tested to identify women at risk for preterm labor: It spikes approximately two weeks prior to the onset of labor
