Abs lymphocytes is the total count of lymphocytes. Lymphocytes are one of the types of white blood cells. The others are neutrophils, basophils, eosinophils, monocytes and macrophages. Normally lymphocytes are about 1.3 to 4.0. What is considered "normal" varies a bit from lab to lab depending on what equipment they use. Whatever is considered as "normal" in your lab should be reported as the "reference range." Viral infections and poor nutrition are the most common reasons for a low count. Depending on how often this shows up and your overall clinical picture, you doctor may want to order another test to determine which types of lymphocytes (T-cells, B-cells, natural killer cells) are low. That would give the reason.

RDW is red cell distribution width. It is used along with other parts of the blood test, particular MCV to determine the cause of anemia. It's already known that you have anemia so this isn't anything to be concerned about.

Kind regards,
