If you are cold your veins will be more difficult to locate, so making sure you are nice and warm before your blood test will ensure a more efficient procedure. Ideally, wear a short sleeved top with a warm jumper or cardigan over the top.
Keeping hydrated prior to your blood test makes it more straightforward to locate your veins, so drink plenty of fluids for at least 24 hours before your test.
Taking a walk or some gentle exercise will raise your blood pressure which will have the effect of making veins more prominent.
In the hands of a skilled phlebotomist a blood draw should not be painful, but you may experience a slight pricking or scratching sensation as the needle goes in. Topical anaesthetic creams, such as EMLA, are readily available over the counter at many high street pharmacies. These products temporarily numb the skin and to be fully effective usually need to be applied an hour before the blood test.
