Data Element Scope: This value set may use the Quality Data Model (QDM) datatype related to Laboratory Test. Used for HIV screening.
Inclusion Criteria: Includes only relevant concepts associated with laboratory tests for HIV-1 and HIV-2 antibodies or antigens.
Exclusion Criteria: Excludes tests and procedures that might be associated with HIV infection that are not used for screening or testing to establish an HIV diagnosis, which would include home/self HIV testing, HIV genotyping tests, HIV RNA tests, HIV cultures, clinical codes used to document care provided to HIV-infected patients.
Constrained to codes in the Laboratory Test, Performed: Human Immunodeficiency Virus (HIV) Laboratory Test Codes (Ab and Ag) value set
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).
