What if I'm on HRT or hormonal contraception?

Here's the honest truth: HRT and hormonal contraception are designed to change your hormone levels, so your test results won't reflect what's naturally happening in your body.

Here's what gets affected:

• FSH, LH, Estradiol: These often get suppressed or altered because your body thinks it doesn't need to produce them naturally
• Prolactin: Usually stays put – this one's pretty resilient
• Testosterone: Birth control often increases SHBG (the protein that binds testosterone), so you might see lower readings
• TSH, T4: Your thyroid usually carries on as normal
• Ferritin, Vitamin D: These don't really care what hormones you're taking

If you're on these treatments, your results will be like trying to understand your natural sleep pattern while drinking coffee all day – not impossible to interpret, but definitely trickier. That's why we don't recommend testing while you're on hormonal contraception or HRT.
