Hi after a infected spider bite in 6/ 2011 i had lymph # of 3.1 , lymph % of 30' then in 8/2011 it raised to 3.2 and lymph % 37. rest if cbc normal. ct last month shied several 1 cm nodes. scared?

Normal findings: A normal absolute lymphocyte count is between 1.5 and 4.0. A normal lymph node on ct is 1 cm or less in diameter. Unless there are other issues (symptoms like fever, wt. Loss, sweats, abnormal lymphocytes in blood) what you describe is not abnormal.

NOT TO WORRY,: Your lymphocyte percentage is within normal limit, though lymphocyte % doesn't have to do anything with an infected spider bite 2 1/2 year ago. 1 cm lymph node enlargement is not also an important factor here. As long as the lymph nodes are not enlarging, not to worry. Your doc will know why s/he advised ct, may be for some other reason!
