Value Set Description from VSAC
Clinical Focus: This value set contains concepts that represent hemoglobin A1c laboratory tests.
Data Element Scope: This value set may use the Quality Data Model (QDM) category related to Laboratory Test.
Inclusion Criteria: Includes only relevant concepts associated with identifying hemoglobin A1c laboratory tests.
Exclusion Criteria: Excludes codes that identify hemoglobin A1c laboratory tests that use the International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) protocol and Japanese Diabetes Society (JDS)/Japanese Society of Clinical Chemistry (JSCC) protocol.

Constrained to codes in the Laboratory Test, Performed: HbA1c Laboratory Test value set (2.16.840.1.113883.3.464.1003.198.12.1013)

QDM Datatype and Definition (QDM Version 5.4)

"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.

A QDM Known Issue has been identified related to this datatype. To see this QDM known Issue, please click here.

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).
