Estradiol (E2)
The main oestrogen. Ovaries make most of it in women; in men it comes from converting testosterone.
The main oestrogen. Ovaries make most of it in women; in men it comes from converting testosterone.
It drives the menstrual cycle, and in men a value that is too high or too low both cause symptoms.
In a menstruating woman this number is uninterpretable without the cycle day -- it varies several-fold across a single month, so record the day. The shipped band is an adult-male one and a report's own range should override it.
Worth discussing with the cycle day, or with testosterone in men.
On a report in another language.
A lab report names this analyte in its own language. Vitals Vault recognises each of these and files them all under Estradiol (E2).
