I want to find all instances of Hgb A1C (LOINC:4548-4) test results with any timing, at least two occurrences, and with a specificity scale of 0, grouped under the panel with panel number 1, timing set to ANY, accuracy scale set to 0, and no inversion applied. The query is focused on the Hemoglobin A1C test (LOINC:4548-4) in the Chemistry category, specifically under the Hemoglobin subcategory within the Laboratory tests section. The query is based on the i2b2 query builder xml format and utilizes the specified parameters for defining the query.
