Test ID: FBLP    
B-Cell Lymphoma, FISH, Blood or Bone Marrow

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

Anomalies involving BCL6, c-MYC, and IGL are detected using a break-apart FISH probe. If a MYC abnormality is detected, reflex testing will be performed to identify the translocation partner. Translocations involving fusion of CCND1 and IGH; BCL2 and IGH; MYC and IGH; BIRC3 and MALT1; IGH and MALT1; and MYC and IGL are detected using dual-color, dual-fusion (D-FISH) strategies. A total of 200 nuclei are scored for the break-apart probe set. For each D-FISH probe set, 500 interphase nuclei are scored and results for each abnormal probe(s) are expressed as percent abnormal nuclei.(Brockman SR, Paternoster SF, Ketterling RP, et al: New highly sensitive fluorescence in situ hybridization method to detect PML/RARA fusion in acute promyelocytic leukemia.

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; 6 a.m.-9 p.m., Saturday, Sunday; 6 a.m.-4 p.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.

7 days

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

10 days

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
