What are normal total and direct bilirubin levels? some say for total <1.0, <1.5, or <1.9. my lab used <1.0 and my total was 1.5. direct was 0.2.

Normal values: Direct (also called conjugated) bilirubin: 0 to 0.3 mg/dL Total bilirubin: 0.3 to 1.9 mg/dL

Lab value depends on the lab.: Different labs use different procedure or technique and will give you a lab value for that lab. Normally it is not to worry some in the lab ranges you have quoted. Even if it gets slightly higher it can still be normal for that person because of his genetic makeup.
