Can dehydration cause a false positive on the bilirubin pad of a reagent strip? I have a pack of these strips I got free. I notice if I wake up pretty dehydrated, it will change the color of the bilirubin strip. Usually to a light orangish color. Not really same color on the chart on the bottle. But after I drink anything(water or coffee) and I am hydrated, the bilirubin pad will remain white showing no bilirubin. If this were liver issues, would drinking water cause a false negative? Or is dehydration possibly causing false positive? I have no other symptoms. No abdominal pain, no jaundice, and no pale stools. Thanks.
