Oral birth control pills (OBCPs) suppress the body’s natural hormone production by preventing ovulation and lowering levels of LH, FSH, estrogen, and progesterone. As a result, urinary hormone testing will typically show low or flat levels of these hormones.
It’s also important to note that the Hormone Zoomer does not detect synthetic hormones—such as ethinyl estradiol or progestins—so results may not reflect the individual’s total hormone exposure while on OBCPs.
Because of this, testing while taking OBCPs is not a reliable method for evaluating endogenous hormone production or identifying the root cause of hormonal imbalances.
If clinically appropriate, it is ideal for individuals to be off oral contraceptives for at least three full cycles prior to testing in order to obtain an accurate picture of their natural hormonal activity.
However, patients should consult their ordering healthcare provider to determine whether to continue or temporarily discontinue oral hormone therapy prior to testing. Do not stop or alter medication use without provider guidance.
