Test ID: HEVM    
Hepatitis E Virus IgM Antibody Screen with Reflex to Confirmation, Serum

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

Highly purified recombinant hepatitis E virus (HEV)-ORF2 (from HEV genotypes 1 and 3) viral antigens are fixed to microplate wells. Diluted patient serum specimen is incubated in the well, in which antibodies bind specifically to the HEV recombinant antigens coating the surface of the well. Unbound human antibodies are then washed away, followed by addition of anti-human IgM antibodies that are conjugated to horseradish peroxidase enzyme for incubation. Unbound conjugate antibodies are then washed away, and a chromogenic substrate is added to the well. Human anti-HEV IgM antibodies specifically bound to the HEV antigens in the wells are detected by the peroxidase-catalyzed color reaction. Intensity of the color as measured with a photometric analyzer is proportionate to the quantity of bound HEV IgM antibodies present in the serum specimen.(Package insert: recomWell HEV IgG/IgM kit, catalog no. 5004/5005,; MIKROGEN GmbH, Foster, Neuried, Germany, rev 2/2009)

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.

Tuesday, 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.

5 days

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

9 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

Rochester
