Test ID: FPCPD    
Plasma Cell Proliferative Disorder (PCPD), FISH

‹ Back to Hematology index

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

This test uses commercially available and laboratory-developed chromosome-specific fluorescent-labeled DNA probes for FISH. Bone marrow samples are processed to keep the cytoplasm of the leukocytes intact. At least 2 slides with 2 hybridization sites each are prepared using a cytospin centrifuge. Each probe set is hybridized to a separate hybridization site. Plasma cells are specifically detected by using immunoglobulin staining techniques with commercially available antibodies (cIg) for kappa and lambda. Deletions or monosomies of chromosomes 13 and 17 are detected using FISH enumeration strategies. Centromere probes are used to detect chromosomal aneusomies for chromosomes 3, 7, 9, and 15. Translocation involving chromosome 14 (IGH) with chromosomes 4 (FGFR3), 11 (CCND1), or 16 (MAF) are detected by D-FISH strategies. For each probe set, 50 plasma cells (if possible) are scored and the result for each probe is reported.(Shaughnessy J, Tian E, Sawyer J, et al: High incidence of chromosome 13 deletion in multiple myeloma detected by multiprobe interphase FISH.

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.

Samples processed Monday through Sunday. Results reported Monday through Friday, 8 a.m.-5 p.m. CST.

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.

10 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
