But lymphocytes count in absolute lucocyte count is always below range and keep on decersing. In his recent report his lymphocytes in dlc is 46% which is in range. But its lymphocytes in absolute lucocyte is 2.57 and range is 6-9 . Is it need to concern. Iam very worried. Plz help should i take him fir hiv test.
