It can be difficult to get enough blood but there are a few things you can do to make it easier:  Make sure your hands are warm – jogging on the spot, shaking your hands, holding a warm mug of tea or putting them in warm water will all help.  The ring finger (next to the little finger) or middle finger are the easiest to get a sample from.   Prick your finger at the side closer to where your nail is rather than in the middle.  Remember the lancets (finger pricks) can only be used once. If you run out and haven’t been able to complete the test, you can order another test or visit your nearest clinic where they can give you another test or take the blood test in person. Don’t try to draw blood using anything else – it may put you at risk of infection.  Some people are not comfortable with collecting their own blood sample, and that’s completely fine.  If this is you, you can go to your local sexual health clinic where they can take a blood sample for you.
