Test ID: BA190    
BCR/ABL1, p190, mRNA Detection, Reverse Transcription-PCR (RT-PCR), Quantitative, Monitoring Assay, Varies

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

Total RNA is extracted and reverse transcribed to cDNA. Quantitative real time PCR is performed and p190/ABL quantitative levels are determined using Taqman-type probe technology. The data is analyzed for relative quantification with calibrator normalization and efficiency correction. The reference gene, ABL1, is used to control for RNA degradation in the sample and the calibrator is used to control for inter-run variations. A normalized ratio of BCR/ABL1 (p190) mRNA:ABL1 mRNA is obtained and  reported in the form of a  percentage.(Unpublished Mayo method)

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 Saturday; 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.

4 days

Maximum Laboratory Time Defines the maximum time from specimen receipt at Mayo Clinic 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

RNA 3 months

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