Hey guys, I was wondering which test is best for determinig E2 levels. I read where there are pros and cons for each in silava and blood. From this website it suggest silava....
Why not a blood test? Saliva is the more accurate than blood
serum testing. Only about 1-5% of the hormones in blood are in the
unbound or “free” form. The remaining 95-99% are tightly bound to blood
proteins. It is this unbound, also called bio-available, hormones that
actually enter your body tissue including your salivary glands to do
their work. So it is the bio-available hormone levels that we want to
Any thoughts is appreciated, as i am about to get one of these done on my own.
