Overview
The laboratory findings in a patient with radiation proctitis include anemia, elevated white blood cell, deranged LFTs and electrolyte abnormalities
Laboratory Findings
There are no diagnostic laboratory findings associated with [disease name].
OR
An elevated/reduced concentration of serum/blood/urinary/CSF/other [lab test] is diagnostic of [disease name].
OR
[Test] is usually normal among patients with [disease name].
OR
Laboratory findings consistent with the diagnosis of [disease name] include:
- [Abnormal test 1]
- [Abnormal test 2]
- [Abnormal test 3]
OR
Some patients with [disease name] may have elevated/reduced concentration of [test], which is usually suggestive of [progression/complication].
The initial diagnostic workup for radiation proctitis includes the following:
- A complete blood count shows
- ESR
- Serum albumin
- Electrolyte studies and renal function tests are done, as chronic diarrhea may be associated with
- Hypokalemia
- Hypomagnesemia
- Pre-renal failure
- Liver function tests
- Stool culture, to rule out parasites and infectious causes.
- Stool C. difficile toxin
- C-reactive protein can be measured, with an elevated level being an indication of inflammation.
- sexually transmitted infections testing, particularly in homosexual male or patients with severe rectal symptoms including urgency and tenesmus.
