LaboratoryTestPerformed: Data elements that meet criteria using this datatype should document the laboratory test indicated by the QDM category and its corresponding value set was performed. Timing: The Relevant Period addresses: startTime – When the laboratory test is initiated (i.e., the time the specimen collection begins). stopTime – when the laboratory test is completed (i.e., the time the specimen collection ends). Examples: 1) Initiation of a venipuncture for a fasting blood glucose to the time venipuncture for the fasting blood glucose is completed – basically a single point in time for many specimen collections. 2) Initiation of a 24-hour urine collection for measured creatinine clearance until completion of the 24-hour urine collection Note – the time that the result report is available is a separate attribute than the time of the study (specimen collection)
