Hi @leann1 and welcome to Mayo Connect. We have several members who are curious about purchasing a hemoglobin testing kit to use at home. We know it doesn’t replace professional testing but it surely would be helpful to keep tabs on possible changes in blood numbers in between appointments.

Would you mind telling us which kit you bought? Do you know if it’s pretty accurate comparing it with labs from your doctor?
Have you also been diagnosed with Polycythemia Vera?
