Hepatocellular Carcinoma Risk Panel
Method Description Describes how the test is performed and provides a method-specific reference
Testing is performed using the uTASWako i30 instrument and the test system reagents.
Total alpha-fetoprotein (AFP) is measured by laser-induced fluorescence, with separation of the lentil lectin-reactive AFP-L3 and lectin nonreactive forms of AFP by isotachophoresis of their immune-complexes. Results are expressed as the percent ratio of AFP-L3 to total AFP.(Package insert: uTASWako i30 AFP-L3, Wako Diagnostics, Richmond, VA)
Sample is added to the reagent well with the fluorescent dye labeled anti-human prothrombin antibody (mouse monoclonal) to form the primary immunocomplex. The second labeled antibody solution, anion-conjugated anti-human des-gamma-carboxy prothrombin (DCP) antibody (mouse monoclonal), is concentrated by isotachophoresis when voltage is applied. The concentrated anion-conjugated antibody then reacts with the primary immunocomplex to form the secondary immunocomplex. This secondary complex is further concentrated during isotachophoresis and is separated from unbound fluorescent dye-labeled antibody by capillary gel electrophoresis. The remaining dye labeled DCP is measured by laser-induced fluorescence. The concentration of DCP in the specimen is directly proportional to the amount of fluorescence.(Package insert: uTASWako i30 DCP, version 11.03.08K02. Wako Diagnostics, Richmond, VA)

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, Wednesday, Friday; 10 a.m.
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
Specimen Retention Time Outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded
Performing Laboratory Location The location of the laboratory that performs the test
