JAK2 V617F mutation detection-7781
Test info
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
- Only ONE (1) tube needs to be drawn for any combination of the following tests:
- Calreticulin Exon 9 Assay
- Factor V Leiden Mutation
- Factor 2 Mutation
- Hereditary Hemochromatosis
- JAK2 V617F Mutation Detection
- MTHFR C677T assay
- Immediatley following collection, mix sample by inverting 8 - 10 times to prevent clotting.
Lavender (EDTA), 4mL
