Test ID: AHDV    
Hepatitis D Virus Total Antibodies, Serum

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

This test is performed using a competitive enzyme immunoassay in which hepatitis delta virus-specific antibodies (anti-HDV) compete with virus-specific polyclonal IgG antibody that is labeled with peroxidase (HRP) for a fixed amount of recombinant HDV protein coated on the microplate wells. Patient serum sample is added first to the microplate well, in which anti-HDV IgG and IgM antibodies will bind to the recombinant HDV protein coated in the well. After washing, a polyclonal anti-HDV-enzyme conjugate is added and allowed to bind to unbound recombinant HDV protein coated in the well. After another wash, a chromogenic mixture is added as a substrate for the HRP enzymatic reaction. Concentration of the enzyme conjugate bound to the coated well is inversely proportional to the amount of anti-HDV total antibodies present in the patient sample. The concentration of anti-HDV total antibodies present is determined by comparing the calorimetric reaction signal to a calibrated cut-off signal value.(Package insert: HDV Ab.

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, Thursday; 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.

1 day

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

7 days

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

14 days

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