Pros and Cons of JAK2 testing
My doctor has given me conflicting opinions on whether or not JAK2 testing would advisable. My platelets have been high normal (394-399) since 2016. This year, they were 401. I discussed this with my doctor at my annual physical and he said he wouldn't recommend JAK2 testing because they wouldn't treat me at this platelet level and it could be detrimental to have on my medical record. The retest of platelets 2 weeks later was 404. Tests for inflammation and liver function were normal. CBC with white cell differentiation was also normal. He ordered the JAK2 testing without much explanation. I'm afraid to get this done because of what he said to me during our appointment. I'm concerned a positive JAK2 test might result in a premature diagnosis and prevent further testing/exploration of other possible problems. A negative result doesn't seem definitive either. I'm also concerned about cost and future insurance coverage. On the other hand, knowing either way about JAK2 might provide direction or something to look out for. I'm curious if others are glad they had this test or regret it? Does it make sense for someone whose platelets are only slightly over normal with no symptoms?
