I had blood work done after the completion of my Rituxan. It was called CD19 or CD20 - the results just say not identified. I believe the test is checking for B cells.
Has anyone else had this blood test?

No, never had that test. How were your results of that test?
I am waiting for my Mayo dr to call me and explain it. The nurse of my pulmonologist here in my hometown said the test just read not identified, she wasn't sure what that meant and faxed it to Mayo.
B cells have different proteins on their surfaces that enable them to function, and one of them is called CD20. Because rtx is an antibody to CD20, it binds to CD20 and this kills the B cell. Measuring CD20 shows how well the rtx treatments wiped out your B cell population.
Oh thanks Sangye, I think I asked you about this blood test a while ago and I called it something else, oops!
Reviving this thread to see if anyone has more information.
I just had this test done (4 weeks post last rituxan treatment) and the results came back all zeros. No cd19 b cells and no cd20 b cells.
Is this the desired result? Very little information available in layman's terms and Dr's explanation was as clear as mudd.
