I want to find all patients who have had a urine analysis test with a result of 'AMBER' for the color parameter (LOINC:578-6) within any time frame. This query will search for a specific lab test result within the Urinalysis category, focusing on the color component of the test, using the LOINC code 578-6, and will return results where the value is 'AMBER'. The specificity scale is set to 0, meaning no specificity filtering will be applied, and the accuracy scale is set to 100, indicating that the highest level of accuracy is desired. The query is not inverted, and only one occurrence of the test result is required to meet the criteria.
