Hi, I hope you have seen your doctor since this message. Did he explain why you had the drop in the Lymphocytes? Was this count you are talking about part of the complete blood count that has the percent of cells? Those do have reference ranges, but also, they can vary based on what your neutrophils (white blood cells) are doing. What the laboratory does is read a percentage of cells until they reach 100. Then they get a percent based on how many of each type of cell in 100 cells they see. If the neutrophils (white blood cells, also called "segs" ) are high it can make the other cells appear low since it is a percentage. Let me know if you still have any questions. I can take a look. I need the ranges for your laboratory as well. Usually, the neutrophils are high when you have some type of infection. This would also make the lymph nodes swell sometimes. Did you have any fever or other symptoms at the time?
Also, if your iron is low your red blood cells can have "atypical" look to the lab, or your hemoglobin will be low if you are very anemic. Usually, if you are very iron deficient, you will be extremely tired. You can get an iron, ferritin, total iron binding capacity and/or transferrin. But your RDW on the CBC would be high. Let me know what you find out.
