Where assessment of biochemical hyperandrogenism is important in women on hormonal contraception, drug withdrawal is recommended for months or longer before measurement, and contraception management with a non-hormonal alternative is needed during this time.

Should read:

Where assessment of biochemical hyperandrogenism is important in women on hormonal contraception, drug withdrawal is recommended for 3 months or longer before measurement, and contraception management with a non-hormonal alternative is needed during this time.
