How to prepare for this test

To ensure accurate results:

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

• If you have an irregular sleep pattern, cortisol results may be unreliable. Test within 2 hours of waking and let us know in the supporting information

• 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

• Corticosteroid medication may affect cortisol results — consult your GP before testing

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

• Avoid biotin supplements for 2 days prior (unless prescribed)

• Do not take vitamin B12 for 2 weeks prior unless advised by your doctor

• Hormonal contraception may affect results — for more accurate results, consider pausing and waiting for your periods to resume

• If you take thyroxine, continue as usual

• 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 function
