I want to find patients with a previous diagnosis of diabetes (Essen-Diabe-Insul@10:42:15) who have also been diagnosed with other acute lower respiratory infections (J00-J9) and have had a white blood count (WBC) test (LOINC:690-2) performed. The specificity scale is set to 0, meaning all possible matches will be returned, and the accuracy scale for each panel is set to 100, indicating high accuracy. The query timing is set to SAMEINSTANCENUM, meaning the same instance number will be used for all panels. This query is named "Essen-Other-WHITE@16:25:03".
