<unk>  is an increase in the number or proportion of lymphocytes in the blood. Absolute<unk>  is the condition where there is an increase in the lymphocyte count beyond the normal range while relative<unk>  refers to the condition where the proportion of lymphocytes relative to white blood cell count is above the normal range. In adults, absolute<unk>  is present when the lymphocyte count is greater than 5000 per microliter (5.0 x 109/L), in older children greater than 7000 per microliter and in infants greater than 9000 per microliter. Lymphocytes normally represent 20% to 40% of circulating white blood cells. When the percentage of lymphocytes exceeds 40%, it is recognized as relative<unk> .
