Human Immunodeficiency Virus Hiv Laboratory Test Codes Ab And Ag Performed

Description:

Clinical Focus: Screening for HIV infection

Data Element Scope: Laboratory tests used for HIV screening. The scope of the value set is to include some secondary HIV tests that may be present in an EHR to assure a measure of screening does not miss patients who are tested and avoid unnecessary retesting to meet the expectations of a quality measure.

Inclusion Criteria: Laboratory tests for HIV-1 and HIV-2 antibodies or antigens.

Exclusion Criteria: Home HIV testing, HIV genotyping tests, HIV RNA tests, HIV cultures, clinical codes used to document care provided to HIV-infected patients.

Subject constrained to the Human Immunodeficiency Virus (HIV) Laboratory Test Codes (Ab and Ag)

QDM Datatype: LaboratoryTestPerformed

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: 1) 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. 2) 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)
