This test was developed and its performance characteristics determined by ARUP Laboratories. It has not been cleared or approved by the US Food and Drug Administration. This test was performed in a CLIA certified laboratory and is intended for clinical purposes.
Laboratory Developed Test (LDT)
If JAK2 V617F is reported as "Not Detected" then CALR Exon 9 Mutation Analysis by PCR will be added. If CALR is reported as "Not Detected," then MPL Mutation Detection will be added. Additional charges apply.
