… Obtain labs (CBC, CMP with LFTs, lipase, urinalysis, pregnancy test in reproductive-age women) and RUQ ultrasound as first imaging, then direct further workup by ultrasound findings, cholecystectomy for acute cholecystitis, MRCP for suspected choledocholithiasis based on risk stratification (e.g., high-risk criteria including CBD dilation >6 mm, bilirubin >4 mg/dL, or gallstone pancreatitis), CCK-HIDA/GBEF for acalculous functional gallbladder disorder, and cross-sectional imaging for liver masses or other pathology.

Our full summary of this standard
For right upper quadrant pain, characterize the pattern (acute vs chronic, post-meal vs unrelated, with vs without fever/jaundice) and triage acute red-flag presentations (Murphy sign, Charcot's triad, painless jaundice with weight loss, pregnancy with LFT/coagulation derangement) to the ED. Obtain labs (CBC, CMP with LFTs, lipase, urinalysis, pregnancy test in reproductive-age women) and RUQ ultrasound as first imaging, then direct further workup by ultrasound findings, cholecystectomy for acute cholecystitis, MRCP for suspected choledocholithiasis based on risk stratification (e.g., high-risk criteria including CBD dilation >6 mm, bilirubin >4 mg/dL, or gallstone pancreatitis), CCK-HIDA/GBEF for acalculous functional gallbladder disorder, and cross-sectional imaging for liver masses or other pathology.
