hi kaypeeoh,

I'm not sure why it seems that the sticks seem to only test positive for either ketones or bilirubin but not both together? But I do know that high levels of vitamin C will cause a false positive reading for bilirubin. So, if you're taking supplements, that may be the reason for that. Metabolites of aspirin or other salicylates, and sulfa drugs or sulfates may also trigger a false positive reading.

Otherwise, positive urinalysis for bilirubin isn't really significant unless there are other signs of liver or gallbladder disease.

hth,
