(17:37:14) laytos115: Hello everyone would like some advice please, can anyone tell me what the cost would be to visit a Doctor and also get a blood test for myself who is currently on holiday in Calis. Before leaving the UK I had a blood test and was told it may be a B12 deficiency. Since I have been here which is two weeks so far I have been suffering days where just not feeling too good, and someone recommended that I go to the hospital and get a blood test. Would like to know few things! Which hospital do I go to, and also would anyone know the cost of the blood test please. Many thanks Sandra
