A general screening includes (with further information in sections below):
*A severity grading of '''previously known liver diseases'''.  
*Looking at the '''referral/requisition form''' {{Moderate-begin}}and looking at the medical records{{Moderate-end}} for particular conditions to look for or evaluate. {{Moderate-begin}}Perform a severity grading of '''previously known liver diseases'''.{{Moderate-end}}
