A member asked:
Bilirubin normal at 19 umol/l in one city but i moved & new lab has lower reference where 17 umol/l is normal limit vs 20. if im still 19 is this a problem or do calibrate machines differently from lab to lab so different results for same sample? tx?
A doctor has provided 1 answer
Different machines use different samples for calibration. Once calibration is complete, all machines will come out with the same lab results. Value of 19 is not high for bilirubin, nothing needs to be done for this value until associated with signs or symptoms of biliary obstruction or liver cell disorders. Hope you helps.

My ALT is 140, AST is 40, and Bilirubin is 0.3. I haven't spoken with my doctor because the results came directly from the lab. What does it mean if you have high ALT, but normal AST? I'm worried.

My Bilirubin level year ago was 18 umol/l which was normal range of less than 20. Moved to a different city and have exact same result of 18 umol/l but this city has a lower reference range of 17 max so now this is not normal??? Is this a concern?

Why do different labs set different limits for the high limit of amylase (some 100, some 110 others 140) ? My recent Amylase level is 140. But the high limit of the lab I used is 110uL making my level High. But if another lab did it, Id be normal?
What could have raised my globulin levels from 2.5 to 3.2 in 3 weeks. I only recall 1-2 days of loose stool 2 days before lab + stress. All bloodwork within normal limits. Was also different lab. A/G ratio decreased from 1.9 to 1.3. Serious?
