By Theodore Zava, ZRT Laboratory  ZRT Laboratory has been working with dried samples for over 15 years, and the number of tests we offer using dried urine and blood spot make us the world expert on dried sample validation and commercialization.

We are seeing plenty of patients with abnormal salivary cortisol profiles, absent, blunted or exaggerated cortisol awakening responses, and symptoms typical of both high...
