  In the realm of healthcare diagnostics, testing for various hormonal levels holds significant importance in understanding an individual's health. Traditionally, blood testing has been the norm for assessing hormone levels. However, the emergence of saliva testing has brought about a new dimension in evaluating hormones. Saliva testing provides a non-invasive and convenient method for individuals to collect their samples, allowing for a more accurate representation of bioavailable hormones – those readily accessible to target tissues. The Significance of Saliva Testing Saliva testing measures the unbound, bioavailable fraction of hormones, which stands in contrast to blood tests that often reflect...

By Margaret Grove, ZRT Laboratory. Sometimes you look back and wonder where all the time went. Let’s see - in my twenties, the younger, sexier me had been to University and embarked on a career in medical research, and I’d been very active in my leisure time – including hiking and skiing every year in the Alps. I was too invested in my career and hobbies to have children and wanted to put that off until the right time. In my thirties, I eventually realized it was time to start a family before it was too late. At age 35...

Hormone Health Educator Candace Burch hosted an informational webinar explaining how hormones affect our weight - specifically, how they inhibit our ability to lose weight and keep the pounds off. During the webinar, we received many great questions from the audience and Candace has answered them below. I've reduced my stress and eat well, but still have high cortisol levels. What else can I do? It sounds like you are making progress in reducing your stress and eating well, but as someone once said - "it's not always what you're eating, but what's eating you that is the real problem."...

When sex hormones are tested in women either in saliva or blood spot, ZRT test reports give a ratio of progesterone (Pg) to estradiol (E2). The ratio is helpful in clinical practice when both E2 and Pg are within range, yet the patient continues to have symptoms. It is not expected to be normal or used clinically when either E2 and/or Pg are outside of their expected ranges or if the patient does not have clinical symptoms. A low ratio occurs when Pg is low relative to E2. This describes the classic situation of estrogen dominance.  In general, either decreasing estrogen and/or increasing progesterone...
