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

The Viramed Biotech AG Borrelia B31 ViraChip IgM and IgG are protein microarray assays and can be considered modified solid-phase enzyme linked immunosorbent assays (ELISAs). Highly purified antigens from the Borrelia burgdorferi B31 strain, including the 93 kD, 66 kD, 58 kD, 45 kD, 41 kD, 39 kD, 30 kD, 28 kD, 23 kD, and 18 kD proteins, are bound to the solid phase nitrocellulose membrane in triplicate. The positions of these antigen "spots" are well defined and are reliably identifiable using customized software. Each microarray also has "spots" for a negative control, serum controls, conjugate controls, and 6 calibrators. One microarray is fixed to the bottom of a well in a standard 96-well microtiter plate.

 

For each test to be performed, the diluted patient serum is added to each microarray (note: the B burgdoreri IgG and IgM microarrays are in separate wells). If specific antibodies recognizing a B burgdorferi antigen are present, they will bind to the specific antigens on the microarray. After incubation the microarray is washed to remove unbound antibodies. Alkaline-phosphatase antihuman IgG or antihuman IgM (conjugate) is then added to the well and incubated. If antibodies are present, the conjugate will bind to those respective antibodies, and after a washing step to remove unbound conjugate, substrate solution is added. If the antibody/conjugate complex is present, the substrate will undergo precipitation and color change. After an incubation period, the reaction is stopped and the presence of precipitated substrate is visualized at specific locations on the microarray. The presence of a colored precipitation at various locations on the microarray is an indirect measurement of B burgdorferi specific antibodies in the patient specimen. Visualized spots from the reaction are compared for intensity with the integrated calibrator controls for evaluation.(Package inserts: Borrelia B31 ViraChip IgM and Borrelia B31 ViraChip IgG.

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 Friday; 9 a.m.

Saturday, Sunday; 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 Clinic Laboratories until the release of the test result

3 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
