Overview

An elevated/reduced concentration of serum/blood/urinary/CSF/other [lab test] is diagnostic of [disease name].

OR

Laboratory findings consistent with the diagnosis of [disease name] include [abnormal test 1], [abnormal test 2], and [abnormal test 3].

OR

[Test] is usually normal for patients with [disease name].

OR

Some patients with [disease name] may have elevated/reduced concentration of [test], which is usually suggestive of [progression/complication].

OR

There are no diagnostic laboratory findings associated with [disease name].

Laboratory Findings

• Quantitative analysis of fat in the stool may be helpful in the diagnosis of steatorrhea. The various tests that may be helpful in the diagnosis are:
  • Biochemical assay
  • Acid steatocrit
  • Near-infrared reflectance analysis (NIRA) (considered to be most accurate)
  • Assessment of fecal fat: Fecal fat excreted in healthy individuals is usually around 6g per day. In conditions such as diarrhea and associated diseases, the amount of fat excreted is on a higher side comparatively and it should not be mistaken as malabsorption.
  • Sudan III stain is a qualitative test which may be helpful in determining the condition steatorrhea in most patients in a very less time compared to the stool collection test.
