I want to find all instances where the LD Isoenzymes, MP (LOINC:5910-5) lab test result is within the normal range for a patient, with no specific time frame, and the specificity scale is set to 0, meaning that the query will return all possible results without any restrictions, and the accuracy scale is set to 100, indicating that the query will return the most accurate results possible. The query will only include one item in the panel, which is the LD Isoenzymes, MP (LOINC:5910-5) lab test, and the icon used to represent this item will be LA. This query will return lab tests that are classified under the category of Encounter (ENC).
