Hi @rimmy2 In followup to conversation from yesterday, from my understanding, there are other monoclonal groups such as MBL which is another form of lymphocytosis which can progress to CLL. Here’s a link to an article on MBL just as an example. https://www.healthline.com/health/cancer/monoclonal-b-cell-lymphocytosis

Your husband is still in the early stages of defining his CLL diagnosis. There can be so many little nuances in our blood chemistry. While we fit a basic ‘mold’ no two of us are alike. So it can take a little sleuthing sometimes to refine a diagnosis. Your husband’s case seems very stable and nothing is changing rapidly. So give the pathologist and your husband’s doctor time to work through this. CLL is a very treatable form of leukemia if your husband ever requires medication.
