Hormone Health Hub: Expert Insights on Testing, Balance & Better Living

By Dr.David Zava, ZRT Laboratory COVID-19 is Making Blood Draw Clinics a Scary Place to Be In today’s scary world of rapidly spreading COVID-19 infections, most individuals are hesitant to have their health care provider, or worse, a stranger at a blood draw clinic, violate their mandated social space of 6 feet to allow them to stick a needle in their vein and draw blood for testing hormones. It is understandable why during the SARS-CoV-2 pandemic both the physician and staff would rather limit physical contact as much as possible with a potentially infectious COVID-19 patient, and vice versa. Some...

By Dr. Kate Placzek, ZRT Laboratory. Many children with Attention Deficit Hyperactivity Disorder (ADHD) struggle with fitting in and according to some experts, may receive as many as 20,000 negative messages by age 10 than their neurotypical peers. Little wonder then that many struggle with self-esteem and the belief that they are somehow broken.

One study found that children with ADHD whose families expressed high levels of criticism failed to experience the usual decline in...

By Dr. Beth Baldwin, ZRT Laboratory If one were to create a word cloud of our clinical consulting calls in 2020, the word “phosphatidylserine” would likely float to the center in a large, bold, brightly colored font.

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

Tracy Tranchitella, ND, ZRT Laboratory. Following on from part 1 of this 3-part blog series discussing 3 important nutrients that can enhance our immune function against viral infection as well as regulate the inflammatory response to COVID-19, this second part of the series discusses the essential mineral zinc. The Many Roles of Zinc The body uses zinc in countless ways. After iron, zinc is the most abundant trace mineral in the body and is present in every cell. Zinc is necessary for the activity of over 50 enzymes that aid in metabolism, digestion, nerve function and many other processes. We need zinc...

Saliva hormone testing is one of the most accurate and convenient ways to measure bioavailable hormones — the fraction that is actually active in your body's tissues. Unlike standard blood tests, which measure total hormone levels including protein-bound fractions that cells cannot use, saliva testing captures only the free, unbound hormones that drive real physiological effects. This guide explains how saliva testing works, which hormones it measures, why it is clinically superior for monitoring hormone therapy, and how to choose the right test for your health goals.
