Determination of human immunodeficiency virus antibody status in forensic autopsy cases in Vancouver using a recombinant immunoblot assay. 1990

Department of Forensic Pathology, University of British Columbia, Vancouver, Canada.

Sera from 207 forensic autopsy cases were tested for the presence of antibody to the human immunodeficiency virus (HIV) using a recombinant immunoblot assay (RIBA) technique developed by Chiron Corporation of Emeryville, California--the Chiron RIBA-HIV216 test system. Out of these cases, 172 autopsies were of individuals with no known risk factors for HIV infection, and of these, 169 had no detectable antibodies to HIV. In 2 cases, the serum reacted with p24 alone on the RIBA-HIV216 assay, but these results were not confirmed by further testing and are considered to be false positive reactions. In 1 case, the serum reacted only with gp41 on the RIBA-HIV216 test but was nonreactive with further testing. This result has been designated equivocal. Of the 35 cases at high risk of HIV infection, 4 had antibodies to HIV detected in postmortem serum samples. The sensitivity (100%) and specificity (98.5%) of the RIBA-HIV216 test system are high. However, the test appears to be more suitable for routine diagnosis of HIV infection than for rapid screening in the mortuary.

D008297	Male		Males
D011237	Predictive Value of Tests	In screening and diagnostic tests, the probability that a person with a positive test is a true positive (i.e., has the disease), is referred to as the predictive value of a positive test; whereas, the predictive value of a negative test is the probability that the person with a negative test does not have the disease. Predictive value is related to the sensitivity and specificity of the test.

D004797	Enzyme-Linked Immunosorbent Assay	An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.

D005189	False Positive Reactions	Positive test results in subjects who do not possess the attribute for which the test is conducted.

D005455	Fluorescent Antibody Technique	Test for tissue antigen using either a direct method, by conjugation of antibody with fluorescent dye (FLUORESCENT ANTIBODY TECHNIQUE, DIRECT) or an indirect method, by formation of antigen-antibody complex which is then labeled with fluorescein-conjugated anti-immunoglobulin antibody (FLUORESCENT ANTIBODY TECHNIQUE, INDIRECT). The tissue is then examined by fluorescence microscopy.
