In the second half of the normally developing inflammatory process, in most cases the relative amount of B-lymphocytes in the blood rises (especially in viral infections). As a rule, this indicator increases in parallel with the increase in regional lymph nodes. The relative content of B-lymphocytes usually increases with prolonged inflammatory processes. For the clinician, the most important is the analysis of the level of B lymphocytes after the end of the clinical manifestations of the inflammatory process. In all cases, the normalization of the relative amount of B-lymphocytes indicates a complete end of the process.
Diseases and conditions in which the amount of CD20 lymphocytes in the blood changes
