What Does The Fluctuating Bilirubin Level Indicate?

Hello Doctor, I am a 53 y.o. female, 5 4 , 190 lbs. Recent CBC came back with these results: Bilirubin total :1.5 (ref. int. was 0.0-1.2) and Bilirubin indirect: 1.21 (ref. int. was 0.10-0.80). All other liver enzymes were normal. (only other elevation was cholesterol and CRP.) I am concerned about the elevated bilirubin levels. Are they considered very high? Does the fact they are high (even with other liver enzymes normal) mean there could be a liver problem? I can t seem to find definitive answers on websites. At the moment I don t have a primary physician to ask. Have read that if all other liver enzymes are normal, etc., that elevated bilirubin shouldn t be a concern. Is this true? And can bilirubin levels fluctuate ad go up and down for certain reasons? (Stress, etc.)? Would appreciate any answers to these ?s as I m very worried about whether this is a very serious concern. Thanks very much in advance.
