JAK2 V617F mutation detection
  
7781
  
LAB7781
  
JAK
  
JAK2
Janus Kinase 2
Tyrosine Kinase mutation
  

Detection of point mutation (G to T mutation in exon 12 resulting in the V to F amino acid change at position 617) of the human JAK2 gene. This mutation is associated with myeloproliferative disorders.

 

Specimen

  
EDTA whole blood
  
  
3.0 mL
  
  • Only ONE (1) tube needs to be drawn for any combination of the following tests:
    • Calreticulin Exon 9 Assay
