I recently received blood test results, showing that I had raised bilirubin levels (27 umol). I would consider myself to be a healthy 40yr old. I drink very moderately, average weight, exercise regularly and do not smoke . My general practitioner was not concerned by this result as all the other results were within normal ranges. However, I am very worried about the raised bilirubin, as from what I have read this is usually a symptom of underlying liver disease . Is there any reason why bilirubin might have been temporarily raised? I fasted for 14 hrs before the test and had a medium sized dark bruise on the day if the test due to an earlier injury. Could these factors explain the high levels?
