ARDMS RDMS AB-Abdomen Question # 45 Topic 5 Discussion

Before performing a paracentesis, assessment of the patient's coagulation status is crucial to minimize bleeding risk. The International Normalized Ratio (INR) is the standard lab value used to assess coagulation. Elevated INR may increase the risk of bleeding complications during the procedure. ALT, AFP, and bilirubin levels evaluate liver function or cancer progression but are not directly relevant to bleeding risk for this procedure.

As per AASLD and SIR guidelines:

“An INR and platelet count should be evaluated before paracentesis to assess bleeding risk. Minor elevations in INR (<1.5) may not contraindicate the procedure.” (AASLD Practice Guidance, 2021; SIR Consensus Guidelines, 2019).
