Value Set Description from VSAC

Clinical Focus: This value set contains concepts that represent laboratory tests used for Human Immunodeficiency Virus screening.
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 (2.16.840.1.113762.1.4.1056.50)

QDM Datatype and Definition (QDM Version 5.3)

"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).

QDM Attributes

relevantPeriod

Relevant Period addresses the time between the start of an action to the end of an action. Each datatype using relevant period defines specific definitions for the start and stop time for the action listed.
