Just because a woman has a normal cycle does not necessarily mean she’s ovulating and her pituitary hormones are signaling as they should. Saliva hormone panels will tell the true story because saliva testing measures what’s biologically available and active in the tissue at the optimal times during the month, rather than a blood test taken at a random time during the month. Hormones live primarily in the endocrine glands, not in the blood as red blood cells, and other values included in a complete blood count and metabolic panel.
