Epic Code LAB3640 JAK2 V617F Mutation, do MPN if Negative

Important Note

The same sample may be used for both JAK2 V617F and MPN Expanded Panel testing.

Test Name Alias

MPN Expanded Panel | CALR MPN Expanded Panel | JAK2 Exon 12 MPN Expanded Panel | JAK2 V617F Mutation Analysis | LAB3612 | 7135 | MPL MPN Expanded Panel

Interface Order Alias

55091

Clinical Information

The JAK2 V617F Mutation assay uses next generation sequencing to detect the presence of the V617F mutation which can be used to monitor disease progression in certain myeloproliferative disorders.  If the JAK2 V617F mutation is absent, the MPN Expanded panel will automatically reflex.

 

The MPN Expanded panel assay uses next generation sequencing and fragmentation analysis to detect well defined mutations in CALR exon 9, JAK2 exon 12 and MPL exon 10, which, in addition to BCR-ABL gene fusion and JAK2 V617F mutation testing, aids in the diagnosis of Myeloproliferative Neoplasms.
