Specimen Collection

NOTE:

Do not collect samples on a Friday, the weekend or the day falling immediately prior to a long weekend. These samples may be rejected and a re-collect required.

RNA is highly unstable and specimens degrade rapidly. For optimum results samples should be sent in CPD tubes at room temperature and be received by this lab within 24 hours of collection. Although LabPlus operates 24 hours a day, 7 days a week, the Molecular Haematology section only operates 9-5, Mon-Fri (excluding public holidays). Samples arriving on a Friday afternoon or a Saturday or Sunday may not get processed until the following Monday. Such delays can significantly compromise the quality of the sample.

9 mL CPD Blood (Preferred)

2 mL CPD Bone Marrow (Preferred)

9 mL EDTA Blood

2 mL EDTA Bone Marrow
Turnaround Time: Within 2 weeks, 4 days
Diagnostic Use and Interpretation

This PCR tests for the presence of a FIP1L1-PDGFRalpha fusion transcript resulting from a deletion in chromosome 4q12 which joins together parts of the FIP1L1 and PDGFRalpha genes. In some cases of hypereosinophilic syndrome the chimeric FIP1L1-PDGFRalpha tyrosine kinase created by this fusion is constitutively activated. The FIP1L1-PDGFRalpha tyrosine kinase is a therapeutic target of Imatinib (Gleevec) .
