How responsive is Bilirubin to Alcohol consumption? Will excessive drinking for one week impact test results during that period?

Depends. Depending on the amount of intake, alcohol may induce hepatitis and that would raise bilirubin. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex, if you have sex.
