Hello, I am asking this question regarding a diagnosis my husband had from a local doctor. However, I am not sure what this diagnosis means. The doctor he saw stated he wants to test him for Lymphocytosis. My husband is 75 years old and has a few medical problems, i.e. takes Coumadin for several blood clots over the last 7-8 years (none since being on Coumadin), has severe problems spinal pain and blood flow to both legs. However, why do you think he is being tested for Lymphocytosis? Thank you very much, I appreciate your taking the time to assist me with this question. Sincerely, Lynn
