A serum sample that is extremely icteric derives its color from which analyte?

Explanation:
An extremely icteric serum turns yellow because bilirubin, a bile pigment, is present at high levels. Bilirubin comes from the breakdown of heme and, when processed by the liver, can accumulate and impart that distinctive yellow color to the serum. Lipids cause a milky or opaque appearance (lipemia), while electrolytes and glucose do not color the serum. So the color is due to total bilirubin, which includes both unconjugated and conjugated forms that contribute to the yellow hue.
