Testing Methods and Safety

Posted by Ben White on

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.

When sex hormone test results show both oestradiol (E2) and progesterone (Pg) within normal ranges, yet symptoms persist, the Pg/E2 ratio provides a critical additional layer of clinical insight. A low ratio points to oestrogen dominance; a high ratio to progesterone dominance — each requiring a different therapeutic response. This article explains how the ratio is calculated, when it is clinically relevant, and how a real-world case illustrates its practical value.
