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)
- 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
- 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).
