@kandyburke. Hi Kandy, welcome to Mayo Connect. CLL is often very slow to progress as in your case where it’s remained stable for almost 10 years. Having an elevated lymphocyte level with your latest blood test doesn’t necessarily mean there’s a change in your CLL. They can rise after an illness or an infection as an immune response.

Did your doctor run a CBC with differential which breaks down the different types of white blood cells? Do you have a consultation scheduled to talk over the results with your doctor?
