What causes high Bilirubin direct and low TIBC?

High Bilirubin direct and low TIBC can be caused by many reasons.

If your Bilirubin direct is in between 0.1 mg/dL and 0.2 mg/dL and your TIBC is in between 250 mcg/dL and 450 mcg/dL then you need not worry as these are the normal ranges for Bilirubin direct and TIBC respectively. But if your levels are lesser or greater than the above values, then there may be some problem in your body.
