The examination generally includes: liver function, chest X-ray, blood routine, urine routine, stool routine, blood pressure, cardiopulmonary auscultation, skin and so on. Under normal circumstances, as long as the liver function is semi-normal, the problem of high total bilirubin is not big, and it is ok according to the regulations.
If your bilirubin is just a little high, it may be the result of any drugs you have taken before or bad habits (such as staying up late and drinking). You should be back to normal after a few days' rest. You can wait a few days if you are not in a hurry.
