Prepare for your test by following these instructions.

Take your sample between 6am and 10am.

Take this test when any symptoms of short-term illness have settled.

Avoid taking a finger-prick sample from a finger used to apply hormone gels/pessaries/patches in the past 4 weeks. Use gloves to apply these.

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

Do not take biotin supplements for two days before this test; discuss this with your doctor if it is prescribed.

If you take levothyroxine or desiccated thyroid extract (DTE), take your blood test before your dose for the most accurate thyroid function results.

If you have to take your blood test later in the day, aim to leave at least six hours between taking levothyroxine medication and your blood draw (or 12 hours after DTE/T3 medication).

Please also let us know in the supporting information if you take amiodarone or lithium, as these can also affect your results.
