The DeMeester Score threshold for diagnosing pathologic GERD is:
DeMeester Score — GERD Threshold
Score > 14.72 = Pathologic (abnormal) acid reflux, indicating GERD
A normal DeMeester Score is < 14.7.
What the Score Measures
The DeMeester Score is a composite scoring system developed by DeMeester and Johnson from 24-hour ambulatory pH monitoring. It combines six components:
- Number of reflux episodes per day
- Number of long reflux episodes (> 5 minutes) per day
- Longest reflux episode duration
- Total time with pH < 4.0
- Upright time with pH < 4.0
- Supine time with pH < 4.0
Clinical Significance
- A DeMeester score > 14.72 OR total distal esophageal acid exposure time > 5–6% are the commonly used thresholds for pathologic reflux.
- The score correlates clinically with GERD severity — it reflects the pattern of reflux and esophageal clearance.
- However, according to current guidelines (Lyon Consensus), acid exposure time (AET) is now considered more reliable than the DeMeester Score and is preferred for diagnosis of GERD.
- Patients with a normal DeMeester score and normal acid exposure time should not be considered for antireflux surgery.
