Which tests are part of the initial evaluation for acute cholangitis?

• A. Liver enzymes, Lactic acid, Chest X-ray, Blood cultures
• B. CBC, Lipase, INR, CT abdomen
• C. Lipid panel, Electrolytes, EKG, Urinalysis
• D. CBC, Electrolytes, Lipase, INR

Answer: (A)

Initial evaluation for suspected acute cholangitis focuses on confirming infection and assessing how severely the patient is affected. Liver enzymes reflect biliary obstruction and liver inflammation from the cholangitis, so they help show that the biliary tree is involved. Lactic acid levels indicate tissue perfusion and sepsis severity; a higher lactate signals a more unstable patient who may need aggressive resuscitation and prompt antibiotic therapy. Blood cultures are essential to identify the offending organism and guide targeted antibiotics. A chest X-ray is often part of the initial septic workup to rule out another infection source, such as pneumonia, and to assess overall cardiopulmonary status that could affect management. While imaging of the biliary tract (like ultrasound) is important in evaluating the obstruction itself, the combination above captures the immediate labs and cultures that define the initial workup for acute cholangitis.
