How often should I have my blood tested in a year? Now attend nurse led clinic once a year instead of liver specialist. Bloods referred to at last appointment were a year old and no request to have more done. Back to clinic in August and GP surgery say they must receive a request from the hospital before they will do bloods to send. Puzzled? Diagnosed with PBC in January 2011 and take URSO. Suffer fatigue and joint pain and have steadily put on weight since taking URSO despite cutting back portions and eating healthily.
