You should also avoid caffeine for 12 hours and alcohol for 36 hours in advance of the test.
Make sure you're hydrated
Drink at least 500ml of plain water 1-2 hours prior to taking the test and 2-3l extra the day before the test as hydration can affect your results and how well blood will flow.
Stay warm
Make sure to keep warm prior to your blood test as this will help to speed up the procedure.
On day of taking the test
When you attend the clinic you must take your Omnos test kit with you (including the lab requisition form containing your unique Barcode ID) as the clinic will not provide this.
Depending on the clinic provider you may also be required to take photographic ID to confirm you are the person who made the booking.
Please ensure the components in your test kit are kept sealed prior to the appointment to
ensure they are sterile.
