["Laboratory Test, Performed": "Varicella Zoster Antibody Test (IgG Antibody Presence)"]
Data Element Scope: This value set may use the Quality Data Model (QDM) datatype related to Laboratory Test, Performed.
Inclusion Criteria: Includes only relevant concepts associated with tests measuring the presence of IgG antibody to varicella zoster in serum, CSF and body fluids.
Exclusion Criteria: No exclusions.
Constrained to codes in the Laboratory Test, Performed: Varicella Zoster Antibody Test (IgG Antibody Presence) value set (2.16.840.1.113883.3.464.1003.198.12.1067)
"Laboratory Test, Performed"
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:
- 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).
