Tests on a cycle day
Some hormone tests are taken on a set day of the cycle. From the first day of your last period, the laboratory works out the right day, books your visit and reminds you the day before.
Why a set day
FSH, LH and estradiol vary through the cycle: your doctor asks for them between day 2 and day 5, day 1 being the first day of your period.

Work out the day and book
The cycle day is the one your doctor asked for; if in doubt, ask them.
