Capillary Blood Spot Hormone Test Profiles
NEW! HORMONE TESTING JUST GOT EASIER!
Capillary Blood Spot Hormone Profiles for Men and Women
ZRT Lab has made capillary blood spot testing available to measure bioavailable hormones. This is the same hormone profile recommended by Dr. John Lee, but Dr. Zava of ZRT can now extract it from capillary blood taken from the finger. It's a fast, easy and accurate test for those for whom saliva testing may not be the appropriate fluid for measuring hormones.
Capillary blood spot testing offers:
1. Better and more accurate method than saliva to detect bioavailable hormones in individuals using hormonal troches or sublingual drops.
2. Good alternative for individuals who have a dry mouth and cannot produce enough saliva over a reasonable time frame (30 minutes).
3. Individual preference for and familiarity with blood serum testing and blood ranges.
4. Better method than serum venipuncture to detect bioavailable hormones in individuals using topical hormone supplements.
5. Combination of SHBG (male and female) and PSA (male) provides additional information about the overall estrogen burden, bioavailable fraction of testosterone, menopausal status, and potential for overdosing with estrogen or testosterone therapy.”
Here's where to find all blood spot test kits, including individual hormones.
