How to prepare for this test

To ensure accurate results:

• Take your sample between 6:00 AM and 10:00 AM

• Avoid vigorous exercise and sexual activity for 48 hours beforehand

• Avoid nipple stimulation or heavy meals prior to testing (to reduce prolactin spikes)

• Only take the test when any short-term illness has resolved

• If you have periods, take the test 2–5 days after your period begins (ideally on day 3)

• If you do not have periods, the test can be taken at any time

• Avoid fatty foods for 8 hours before your test (fasting is not required)

• Stay well hydrated

• Do not take biotin supplements for 2 days before your test (unless prescribed – consult your doctor)

• Take your sample at least 24 hours after any vitamin or mineral supplements

• Hormonal contraception may affect results — consider taking a break and waiting for your periods to restart

• If you take thyroxine, continue as normal

• If you take liothyronine or desiccated thyroid extract (DTE), take it after your blood draw

• Let us know if you take amiodarone or lithium, as these may affect thyroid results
