fecal bilirubin

Bile pigment is a general term for a series of catabolic products of iron porphyrins such as heme in the body, including biliverdin, bilirubin, bilirubin and bilirubin. Among them, biliverdin is a precursor of bilirubin, and bilirubin and bilirubin are products of bilirubin. In this type of metabolite, except for the bilirubin, which is colorless, the other components have color, so it is called bile pigment. Bile pigment is the main pigment that makes up the color of normal feces and urine. Basic Information Specialist classification: Digestive examination classification: feces / parasitic examination Applicable gender: whether men and women apply fasting: not fasting Analysis results: Below normal: Normal value: no Above normal: negative: There is no bilirubin in normal stool. Positive: There is no bilirubin in normal human feces. In patients with enteritis and diarrhea, bilirubin can be detected when the contents of the intestines are quickly discharged. Tips: Because the first group of normal intestines has not been established, bilirubin can also appear in feces. Normal value Negative is normal. Clinical significance There is no bilirubin in normal human feces. In patients with enteritis and diarrhea, bilirubin can be detected when the contents of the intestines are quickly discharged. Positive results may be diseases: blood stasis, bile heat, acute yellow precautions Note when checking: Because the first group of normal intestines has not been established, bilirubin can also appear in feces.
