Quizplus · Accepted Answer

Therefore, a high count of lymphocytes can be an indication of these conditions. However, the other types of white blood cells shown (neutrophils, basophils, eosinophils, and monocytes) may also have elevated counts in different conditions, so they cannot be ruled out completely without further information.
