I am a 42 year old male. At last blood screening all tests were normal except I had bilirubin of 2.2. I had an ultra sound and it was normal. Doctor now ordered a Cat Scan. I am worried. I am a moderate drinker (3 to 4 nights per week consuming 2 to 3 drinks). I excersize frequently including a long run the morning of my blood test. I was also dehydrated. I have anxiety. What do you think?
