JAK2 detection accuracy
Hello, my 22 year old son had a DVST about five months ago and following with all the testing his blood test showed less than 1% JAK2 was repeated and showed a 1% JAK2 He just had a bone marrow biopsy done, and it showed no detection of JAK2. This has all been very confusing and conflicting. His blood counts are in normal range. RBC has been slightly high at one blood draw. Before the bone marrow biopsy was done, he was told he had PV and now with the bone marrow biopsy results they are saying no evidence of an MPN. Just don’t know what to believe. Anyone have any input?
