So that we can do the necessary amounts of testing, we ask that you fill your tube to the top line marked on the side of the tube.
If you have managed to fill the tube to the first line (0.5ml), please return your sample to the lab. They will be able to confirm if there is enough blood to test. If there isn’t enough then we will contact you and arrange for a free replacement if this is your first blood collection kit. If you can’t collect enough blood to reach the first line, please email us on firstname.lastname@example.org and we can help you organise next steps.
