I have always had quite tricky veins and nurses always struggle to take bloods. My midwife just about managed a few weeks and got a dribble. Today I went for a NIPT and the nurse couldn't get any blood at all. She said it was their policy only to try twice! I'm going back tomorrow but as the clinic is over an hour away I don't want to have to go back a third time! I have already paid £400 for this test so I'm pretty desperate for it to work tomorrow!! I don't know how many chances they will give me... Has anyone else had problems with veins? And do you have any tips on getting them to play ball!!! The nurse said to be really hydrated but I had drunk a litre of water on the way. I'm not over weight (53kg 161.m) and have normal blood pressure if that makes a difference! Thanks x
