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 among 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

  • Laboratory findings consistent with the diagnosis of toxic megacolon include:
  • Some patients with toxic megacolon may have elevated Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) concentration. Electrolyte disturbances are common secondary to inflammatory diarrhea, steroid use and ongoing gastrointestinal losses. In addition inflamed colon is unable to reabsorb salt and water.
