Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — at home hormone testing

Single nucleotide variations (SNVs) in the enzymes that metabolise estrogen can significantly alter breast cancer risk — in some cases by as much as 12-fold when multiple variants combine. In this detailed scientific overview, Jillian Harrington PhD of ZRT Laboratory explains how variations in CYP11A1, CYP19A1 (aromatase), CYP1B1, COMT and MnSOD affect the estrogen metabolism pathway, why catechol estrogens are dangerous, and how methylation testing can reveal individual vulnerability.

The decline in oestrogen, progesterone and testosterone as we age is one of the primary drivers of skin thinning, wrinkling, dryness and loss of elasticity. But hormones affect skin in more ways than most people realise — from DHT-driven acne and unwanted hair growth to the risks of over-supplementation. This article explains the key hormonal connections to skin wellness and how targeted testing can guide safe, effective hormone use.

At-home hormone testing using saliva, dried blood spot and dried urine collection is not only more convenient than clinic-based blood draws — it is also safer, more accurate for certain hormones, and essential for capturing time-sensitive samples like waking cortisol or first-morning melatonin. This article explains how each collection method works, why dried samples carry minimal infection risk, and how ZRT Laboratory’s CLIA-certified processes ensure reliable results.

Breast cancer is not one disease — it encompasses many distinct types with different attributes, degrees of invasiveness and treatment responses. Understanding the difference between invasive and non-invasive cancers, what hormone receptor status means, and which risk factors are modifiable can help women make more informed decisions about screening, lifestyle and hormone health. This article provides a clear, evidence-based overview.

Breast cancer rates have risen from 1 in 30 to 1 in 8 women over the past 30 years — yet the focus remains on treatment rather than prevention. Drawing on 35 years of clinical experience and infrared thermography, this article makes the case that environmental toxins, xenoestrogens, hormone imbalance and lifestyle factors may account for 91–93% of breast cancer risk. Prevention, not just awareness, is the real cure.
