ET with JakV176 "possitive" 3 years after beeing JakV167 "negative"?

[Aneliv9]

Is it possible for someone to be JakV167 possitive, 3 years after initial mutation test was: JakV167 negative?

[Rachelthepotter]

Mutations keep on happening, and I guess its quite possible to acquire the JAK2 mutation after tbe first diagnosis . Or maybe the later test was more sensitve.

Yes! I am negative for all mutations but my doctors have said they suspect they will find one eventually.

Im Jak2 negative polycythemia. I read a story about someone who was negative at her gp then went to Hemotologist who found her positive she talked about some tests being more sensitive. I’m going to get the Jak2 done at a different lab! Good luck!
