AML1-ETO/t(8;21) Fusion Transcript Detection
Quantitative RNA-PCR
Indication
For determining the presence or absence of the AML1-ETO fusion transcript that is associated with the t(8;21) chromosomal abnormality seen in a subset of AML-M2 cases. This quantitative test can be used for diagnosis or for monitoring levels of minimal residual disease detection following therapy.
Methodology
RNA is analyzed for AML1-ETO fusion by reverse transcription followed by quantitative real-time PCR using the TaqMan method.
Test Parameters
This assay will detect AML1-ETO fusion transcripts. Values are expressed as a percentage of AML1-ETO to normalizing ABL transcripts. The sensitivity of detection is approximately one in 100,000.
Turnaround Time
Five to 10 working days
Sample Requirements
- 10 ml peripheral blood in purple top tube (EDTA Vacutainer), sent by overnight express mail on wet ice
or - 2-5 ml of bone marrow aspirate in purple top tube (EDTA Vacutainer), sent by overnight express mail, sent on wet ice
or - 10 µg of purified RNA or cDNA, sent by overnight express mail on dry ice.
