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).
Laboratory Test represents a medical procedure that involves testing a sample of blood, urine, or other substance from the body. Tests can help determine a diagnosis, plan treatment, check to see if treatment is working, or monitor the disease over time. This QDM data category for Laboratory Test is only used for information about the subject of record.
