Welcome to Connect @kwmotley Reading through your comments it looks like you’re taking a daily aspirin tablet and had a stroke earlier this year. This most likely had your doctor running additional tests to make sure you don’t have a blood condition which can cause unintentional clotting.

The results of the JAK2 test you had done does show that you have a mutation for the JAK2 gene which can cause various bone marrow disorders.
These are known as myeloproliferative neoplasms (MPNs), where the bone marrow produces too many blood cells.

There are two links I’m posting below for good articles which help explain JAK2 gene and its involvement with blood disorders.

You’ll be having a bone marrow biopsy next to check the over all health of your bone marrow, which is the manufacturing site for your blood and the heart of your immune system. The information from this test will be very helpful for your doctor to come up with a treatment plan to keep you healthy going forward.
Make sure your doctor knows about all the supplements you’re taking as they can have an impact on your blood, along with the aspirin you take daily.
Do you have any questions about the biopsy procedure?
