TitleMedical Laboratory Requisition Extraction
DescriptionOne ServiceRequest per investigation asked for, category SNOMED 108252007 laboratory, with the urgency mapped onto the three request-priority codes; and one laboratory Observation per result the sheet carries, because this form is a requisition and a report on one page. The clinical history rides on every request: a serology result without it is uninterpretable, which is exactly why the form asks for it.
