Test Catalog

Test Name

Test ID: CHAG    
Trypanosoma cruzi Antibody, IgG, Serum

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

The Hemagen Chagas Kit is a qualitative indirect enzyme-linked immunosorbent assay using purified antigens extracted from cultured Trypanosoma cruzi that have been attached to the surface of microplate wells. The presence of antibodies in the test serum is detected by an enzyme catalyzed color change in added 3,3',5,5'-tetramethylbenzidine substrate.(Umezawa ES, Luquetti AO, Levitus G, et al: Serodiagnosis of chronic and acute Chagas' disease with Trypanosoma cruzi recombinant proteins: results of a collaborative study in six Latin American countries.

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; 9 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

8 days

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

2 weeks

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