I want to find all instances of Hgb A1C (LOINC:4548-4) lab test results within the i2b2 database, with no specific time constraint, and with a high level of accuracy, grouped under the category of Chemistry in the Hemoglobin section. The query will specifically search for the Hgb A1C (LOINC:4548-4) lab test code, and the results will be displayed on panel 1. The query has a specificity scale of 0 and an invert value of 0, indicating that the search will include all relevant data without inverting any results. The total number of items to be displayed is 1, and the class of the item is ENC. The tooltip provides additional information about the query, indicating that it will search for the Hgb A1C (LOINC:4548-4) test within the Labtests, Chemistry, Hemoglobin, and GHBA1C groups.
