Do I need to fast for a thyroid blood test?
Not for the Advanced Thyroid Test. i-screen says no fasting is needed, but asks you to stop biotin supplements 72 hours before the blood draw. Other tests have their own instructions at the bottom of each test's page; follow them before you visit the collection centre.
How ordering works
- Order the test online. No GP referral is needed.
- For a blood, urine or breath test, i-screen emails a pathology request form; take it, printed, with ID to one of its designated collection centres. No appointment is needed.
- Results are published to your i-screen dashboard, and you are emailed when they are ready.
i-screen's FAQ says the website price includes all fees and charges and that no Medicare card is needed. Any other collection centre may accept the form, but it will bill you again.
