Overview
A complete blood count (CBC) is performed in patients with neutropenia or who are immunosuppressed. A CD4 count and HIV test are performed in patients with risk factors for HIV. A collagen workup (eg, antinuclear antibody [ANA], anti-dsDNA) may be performed based on the underlying disease.
Laboratory Findings
Eosinophilic Esophagitis
Laboratory findings of the EoE are as follows:[1][2][3][4][5][6]
- There are no specific diagnostic markers to diagnose EoE patients.
- Although not specific, elevated serum IgE level is identified in majority patients.
- Increased peripheral eosinophil count is also seen in the majority of patients.
- There are 3 main ways in which food allergies can be detected in EoE are as follows:
| Test | Procedure | Interpretation |
|---|---|---|
| Skin prick testing | A small amount of allergen is introduced into the skin of the patient through a gentle puncture with a pricking device. |
|
| Atopy patch testing |

Reflux Esophagitis
Ambulatory reflux monitoring
- GERD is mostly diagnosed clinically by the presenting typical symptoms which include heartburn, regurgitation, and dysphagia.
- Correlation of the GERD symptoms with confirmed acid presence by the ambulatory reflux monitoring is strongly suggestive of GERD.
- Ambulatory reflux monitoring is recommended by the American College of Gastroenterology (ACG) as the only laboratory test to determine the presence of acidic reflux in the esophagus.[7]
- Indications of ambulatory reflux monitoring include the following:[8]
- GERD diagnosis if it is not confirmed
- Determine the time of reflux occurrence
- Refractory GERD symptoms
- Preoperative for non-erosive disease
- Ambulatory reflux monitoring is performed in either two ways which include:
- Telemetry capsule (48 hours monitoring)
- Transnasal catheter (24 hours monitoring)
