Test ID: HIVE    
HIV-1/-2 Antibody Evaluation, Serum

Method Description Describes how the test is performed and provides a method-specific reference

The VITROS Anti-HIV 1+2 assay is performed using the VITROS Immunodiagnostic Products Anti-HIV 1+2 Reagent Pack and the VITROS Immunodiagnostic Products Anti-HIV 1+2 Calibrator. An immunometric bridging technique is used, involving a 2-stage reaction. In the first stage, HIV antibody present in the sample binds with HIV recombinant antigen coated on the wells. Unbound sample is removed by washing. In the second stage, horseradish peroxidase (HRP)-labeled recombinant HIV antigens are added in the conjugate reagent. The conjugate binds specifically to any human anti-HIV-1 or anti-HIV-2 (IgG and IgM) captured on the well in the first stage. Unbound conjugate is removed by washing. The bound HRP conjugate is measured by a luminescent reaction. A reagent containing luminogenic substrates (a luminol derivative and a peracid salt) and an electron transfer agent is added to the wells. The HRP in the bound conjugate catalyzes the oxidation of the luminol derivative, producing light. The electron transfer agent (a substituted acetanilide) increases the level of light produced and prolongs its emission. The light signals are read by the VITROS ECi/ECiQ Immunodiagnostic System. The amount of HRP conjugate bound is indicative of the level of anti-HIV-1 or anti-HIV-2 present.(Package insert: VITROS Anti-HIV 1+2, Ortho Clinical Diagnostics Inc., Raritan, NJ; publication no.

Day(s) and Time(s) Test Performed Outlines the days and times the test is performed. This field reflects the day and time the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time required before the test is performed. Some tests are listed as continuously performed, which means assays are performed several times during the day.

Monday through Saturday; Varies

Analytic Time Defines the amount of time it takes the laboratory to setup and perform the test. This is defined in number of days. The shortest interval of time expressed is "same day/1 day," which means the results may be available the same day that the sample is received in the testing laboratory. One day means results are available 1 day after the sample is received in the laboratory.

Same day/1 day

Maximum Laboratory Time Defines the maximum time from specimen receipt at Mayo Medical Laboratories until the release of the test result

2 days

Specimen Retention Time Outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded

7 days

Performing Laboratory Location The location of the laboratory that performs the test
