What Is Murphy's Sign? Complete Guide to Diagnosis & Clinical Significance

Why Murphy’s Sign matters and common misconceptions clinicians face

Murphy's sign is a vital bedside maneuver that can change your pretest probability when you step into the room with a busy schedule and a patient complaining of right‑upper‑quadrant pain and fever. A positive Murphy’s sign markedly increases the probability of acute cholecystitis, so that brief exam can change your pretest probability (positive Murphy’s sign study).

Clinicians often conflate Murphy’s sign with other RUQ maneuvers, which contributes to mislabeling in practice (LitFL discussion). Analgesics or antispasmodics given before the exam can blunt tenderness, producing false negatives (see authoritative review: StatPearls — Acute Cholecystitis). These pitfalls lead to delayed or incorrect diagnosis when unrecognized.

Core definition and explanation of Murphy’s Sign

Murphy’s sign definition and clinical meaning: Murphy’s sign is a bedside physical examination maneuver that reproduces pain and causes inspiratory arrest when the examiner palpates the right upper quadrant (RUQ) beneath the costal margin. This response reflects localized gallbladder tenderness with diaphragmatic descent on deep inspiration, and clinicians use it to assess for acute gallbladder inflammation (LitFL).

The classic maneuver asks the patient to take a deep breath while the examiner applies steady pressure in the RUQ. A positive sign is the abrupt stop in inspiration caused by pain when the inflamed gallbladder contacts the examiner’s hand. This finding is distinct from the sonographic Murphy sign, which is elicited during ultrasound imaging and depends on patient response to transducer pressure rather than bedside palpation (ScienceDirect).

A positive Murphy’s sign increases the likelihood of acute cholecystitis, but it is not diagnostic alone. Reported sensitivity ranges widely, and specificity is higher when the exam sits within a compatible clinical picture; clinicians should interpret the sign alongside fever, leukocytosis, and imaging when appropriate (ScienceDirect; StatPearls). Guidelines and reviews list Murphy’s sign as a useful clinical criterion, particularly in emergency and acute care settings, while emphasizing its role as part of a broader diagnostic assessment (StatPearls).

Key components and elements of Murphy’s Sign

Murphy’s sign is a focused bedside maneuver for suspected gallbladder inflammation. Clinicians can access concise, cited guidance on the technique at the point of care. Authoritative procedural descriptions appear in resources such as LitFL and Physio‑Pedia. Clinicians using Rounds AI can quickly review cited steps and source material during rounds. Rounds AI presents concise technique steps with citations to authoritative texts.

1. Patient supine with arms relaxed.

2. Right hand placed at the gallbladder fossa at the right subcostal, mid‑clavicular line. Technique described in Physio‑Pedia.

3. Ask the patient to inhale deeply while palpating. Palpate as the diaphragm descends, timing pressure with inspiration (LitFL).

4. Abrupt halt of inspiration indicates a positive sign. Sensitivity for the bedside sign varies across studies; interpret with the clinical picture (Tokyo Guidelines 2018 (TG18)).

These common pitfalls include light palpation, excessive pressure, distracting analgesics, and voluntary guarding, which can lead to false‑negative results (Physio‑Pedia). Rounds AI's evidence‑linked summaries can help clinicians check technique nuances and interpret bedside findings.

How Murphy’s Sign works: physiological basis

Inflammation of the gallbladder wall lowers the threshold for visceral pain. Prostaglandins and cytokines released during acute cholecystitis sensitize gallbladder nociceptors, amplifying responses to stretch and pressure (StatPearls; NCBI PMC11888360). Sensitized afferents fire more readily than normal visceral fibers. That sensitization explains why relatively small mechanical forces can produce abrupt, guarded responses on exam.

During deep inspiration the diaphragm descends and the liver–gallbladder complex shifts inferiorly. The moving gallbladder contacts the examiner’s hand or probe, producing sudden stretch of the inflamed wall. That stretch activates the sensitized visceral afferents and causes the characteristic inspiratory arrest or sharp pain (StatPearls; NCBI PMC11888360). This physiologic chain links inflammation, diaphragmatic motion, and the clinical sign.

Reported sensitivity and specificity for the bedside Murphy’s sign vary across studies; a negative sign does not exclude acute cholecystitis. Use in conjunction with labs and imaging. (StatPearls)

Rounds AI surfaces these guideline‑backed ranges with clickable citations so you can verify the underlying studies and recommendations at the point of care.

Physical exam Murphy’s sign therefore has useful positive predictive value when present, but a negative sign does not rule out disease (StatPearls). Ultrasound with direct probe compression of the gallbladder markedly improves detection. The sonographic Murphy’s sign reports sensitivity near 97% and positive predictive value around 93% in prospective studies (PMCID). Use exam findings alongside imaging and labs for clinical decisions.

Clinical scenarios where Murphy’s Sign is used

A positive Murphy’s sign often shapes early decisions for patients with right‑upper‑quadrant pain. Clinicians commonly use it at the bedside to raise suspicion for acute cholecystitis and to prioritize imaging and labs (Mayo Clinic). When combined with clinical context, a focal Murphy’s sign helps triage urgency and next steps rather than providing a definitive diagnosis (Diagnosis and Treatment of Acute Cholecystitis).

• Initial bedside assessment of suspected cholecystitis

• A positive Murphy’s sign increases the pretest probability for acute cholecystitis and commonly triggers urgent ultrasound and labs (Mayo Clinic).

• Differentiating biliary colic from peptic ulcer disease

• In outpatient triage, documenting Murphy’s sign helps avoid unnecessary endoscopy and focuses evaluation toward biliary causes (Diagnosis and Treatment of Acute Cholecystitis).

• Guiding urgency of ultrasound ordering

• Point‑of‑care ultrasound with a sonographic Murphy sign can improve detection compared with the bedside exam alone; reported performance varies by study and operator. Note that Rounds AI links to current guideline and imaging references.

For time‑pressed clinical leaders, situational use matters: in the emergency department, act quickly when Murphy’s sign aligns with systemic inflammation. In clinic, use it to steer imaging choices and reduce low‑yield referrals. Postoperative persistence of the sign warrants further imaging to exclude retained stones or biliary injury (Diagnosis and Treatment of Acute Cholecystitis).

Related exam maneuvers and terminology

Rounds AI helps clinicians distinguish Murphy’s sign from other right‑upper‑quadrant maneuvers by clarifying indications and diagnostic implications. This short guide contrasts commonly confused signs and notes their clinical value. Use these distinctions to choose appropriate imaging and further testing.

• Courvoisier's sign: palpable, non‑tender gallbladder in a jaundiced patient suggesting obstructive biliary disease; high specificity but low sensitivity for malignant obstruction (Rastogi 2018).
• McBurney's point: a localized anterior‑abdominal landmark used to assess appendicitis, not biliary pathology, and should not be conflated with RUQ tests (DrOracle comparison).
• Murphy's punch: percussion over the costovertebral angle (CVA) to elicit renal tenderness, classically associated with pyelonephritis or renal colic; distinct from the inspiratory‑stop Murphy's sign used at the bedside (Merck Manual — Acute pyelonephritis; LitFL Murphy’s Sign).

Murphy's sign in its classic form remains the primary bedside test for acute cholecystitis, positive when deep inspiration causes abrupt cessation due to RUQ pain (LitFL Murphy’s Sign; Medical News Today). Sonographic Murphy's sign is related but relies on targeted ultrasound to localize gallbladder tenderness during probe pressure (MDPI ultrasonography study). Clinicians should interpret each sign in context, combining history, labs, and imaging for accurate diagnosis.

Examples of interpreting a positive Murphy’s Sign

When interpreting a positive Murphy's sign in practice, treat the finding as a directional clue, not a final diagnosis. A typical vignette is a 45-year-old with acute right‑upper‑quadrant pain, fever, and a clear inspiratory arrest on RUQ palpation. Point‑of‑care ultrasound then shows gallbladder wall thickening and pericholecystic fluid, and the clinical picture supports acute cholecystitis. Murphy’s sign has higher value when combined with imaging; imaging typically establishes the diagnosis, and a positive bedside sign increases suspicion (StatPearls). For quick verification of guideline and imaging references at the bedside, Rounds AI helps clinicians find the original sources that support next steps (MDPI).

A second common scenario is a 60‑year‑old with atypical or diffuse abdominal pain and a reproducible RUQ tenderness with inspiratory pause. Ultrasound and CT may be non‑diagnostic, and labs can point toward alternative causes such as biliary colic, peptic ulcer disease, or hepatic abscess. In these cases, a positive Murphy’s sign should prompt targeted imaging and labs rather than immediate surgery; follow‑up tests change management in a meaningful number of patients (PMC). Teams using Rounds AI get faster access to the guideline‑level literature needed to justify and document the chosen diagnostic pathway. Check the cited reviews and studies when a bedside Murphy’s finding alters your differential (StatPearls, MDPI).

Key takeaways and next steps for using Murphy’s Sign effectively

Murphy’s sign is a rapid bedside clue for gallbladder inflammation (Physio‑Pedia). Predictive value depends on pretest probability; proper technique and patient selection influence how likely a positive or negative result is to reflect true disease. You can confirm current metrics and view primary citations in Rounds AI at the bedside.

Perform the maneuver correctly to reduce false negatives. A standardized technique likely reduces false negatives, but exact rates vary by setting and operator.

Pair a positive Murphy’s sign promptly with ultrasonography to improve diagnostic speed. Combining bedside exam and immediate ultrasound reduced time to definitive diagnosis by 30% in a recent cohort study (Gastroenterology Advances).
