If you are not able to fill the tube up to the line then don't panic - you can send in your sample anyway as sometimes the lab are still able to use a smaller sample to complete the analysis.

If you’d rather have a venous sample taken (from a vein in your arm) we can arrange this for you. Just call us on 03450 600 600 and one of our Customer Care Team will discuss the options with you.
