How accurate is saliva testing compared to blood and urine testing?
According to the World Health Organization this method of testing has been used for hormone testing in worldwide comparisons of breast cancer among women living in industrialized vs. non-industrialized countries. Many studies in the scientific literature have shown a strong correlation between the levels of steroid hormones in the blood stream and the bio-available (free) levels of steroid hormones in saliva Saliva testing is the most reliable way to measure free, bio-available hormone activity those hormones actually doing their job at the cell level. Most blood tests do not measure bio-available hormone levels. In addition, saliva hormone testing more accurately reflects tissue uptake and response of hormones delivered (topically) through the skin, in creams, gels, or patches. Blood and urine assays significantly underestimate hormones delivered topically, often resulting in overdosing. What about the accuracy for women taking birth control pills? What is a suggestion for these women

Saliva testing has been used in scientific testing for decades and has been shown to be highly accurate. The World Health Organization (WHO) has used this method of hormone testing in worldwide comparisons of breast cancer among women living in industrialized vs. non-industrialized countries. Many studies in scientific literature have shown a strong correlation between the levels of steroid hormones in the blood stream and the bioavailable (free) levels of steroid hormones in saliva.

Saliva testing has been used in scientific testing for decades and has been shown to be highly accurate. It is the most reliable way to measure free, bioavailable hormone activity — those hormones actually doing their job at the cell level. Standard blood and urine tests do not measure bioavailable hormone levels. Numerous scientific studies have shown a strong correlation between the levels of steroid hormones in the blood stream and the bio-available levels of steroid hormones in saliva. The World Health Organization has used this method of hormone testing in worldwide comparisons of hormone levels among women living in industrialized vs. non-industrialized countries. In addition, saliva hormone testing more accurately reflects tissue uptake and response of hormones delivered through the skin in creams, gels, or patches than blood or urine tests.
