Hematologic Disorders, DNA Extract and Hold, Varies

Use

This test is useful for reserving DNA on any specimen for which molecular analysis requiring DNA may be necessary at a future date. It ensures that adequate material for testing is available. It is frequently useful to obtain DNA from clinical samples containing a hematopoietic neoplasm at the time of diagnosis, ensuring appropriate material is available for molecular analysis should subsequent testing be required. This is particularly important for conditions such as acute myelogenous leukemia where there is a delay before karyotype information, which determines the need for testing molecular prognostic markers, is available, and the diagnostic sample may no longer be available later.
