Testing hormones in saliva and/or blood spot is convenient--without the hassle, pain and expense of conventional blood tests--and without sacrificing accuracy.
Advantages of saliva testing
- Measures bioavailable, active hormone levels
- Painless--no needles
- Measures effectiveness of topical hormones
Advantages of blood spot testing
- Measures larger molecules, e.g. thyroid hormones in whole blood
- Nearly painless finger stick lowers stress of blood drawing which can affect accuracy
The ease and privacy of collecting blood spot and saliva samples at home also allows routine monitoring of hormone levels. Samples are stable for 2 to 3 weeks, need no special handling, and can be mailed to the lab from anywhere in the world by regular postal service.
