Angiography is a procedure at Great Ormond Street Hospital (GOSH) that shows us the blood vessels and organs inside your body. It uses a dye that shows up on x-rays and gives a picture of how the blood is flowing around your body.

Blood glucose test

A blood glucose test is a fairly common procedure that's carried out regularly in hospitals, like Great Ormond Street Hospital (GOSH), and clinics. The test is to find out how much glucose (sugar) you have in your blood.

Blood tests

People have blood tests so that their blood can be checked in a laboratory. The most common blood tests involve checking the cells in your blood including the red blood cells, white blood cells and platelets.

Blood transfusions

You might need a blood transfusion if you lost a lot of blood during an operation or an accident. Or, if you have certain blood disorders like severe anaemia, sickle cell disease or thalassaemia, you might need blood transfusions as part of your treatment at Great Ormond Street Hospital (GOSH).
