The Diagnostic Value of Carnett’s Test with Chronic Abdominal Pain: A Narrative Review

Chronic abdominal wall pain is a poorly recognized cause of chronic abdominal pain, and patients frequently go misdiagnosed despite a battery of medical tests. The Carnett’s test is a diagnostic tool used to distinguish between abdominal wall pain and visceral pain. This review synthesizes the current literature on the Carnett’s test, merges the viewpoints of diverse writers, and evaluates and reports on the Carnett’s test’s applicability.

Several clinical investigations have established the usefulness of the Carnett’s test in the diagnosis of chronic abdominal wall pain. Furthermore, the Carnett’s test is quite useful in determining the depth of the mass and detecting psychogenic abdominal pain. However, its diagnostic use for acute abdominal pain is limited.

The Carnett’s test is a simple and safe point-of-care diagnostic technique, with several studies supporting its usefulness. Early detection of abdominal wall pain is critical for chronic abdominal wall pain therapy. Carnett’s test is very useful in patients with chronic, unexplained local abdominal discomfort who are compliant and do not have a clear rationale for surgery.
