<s>[INST] my 8 year old son has had some swollen lymph nodes. he has no other symptoms. He had a physical by his pediciatrian and she found some more. Thought it was viral and did some blood work. negative mono negative EBV. High lymphocytes, low MPV, low nuetrphils, low monocytes. he has a biopsy schedule. Could it be something serious with out any other symptoms? [/INST] Hi, dairy have gone through your question. I can understand your concern. He has enlarged lymph node. It can be due to reactive hyperplasia due to some infection other than infectious mononucleosis, or it can be due to tuberculosis or lymphoma. It is possible that without symptoms he may have any of these conditions. So go for biopsy. It will give you exact diagnosis. Then he should take treatment accordingly. Hope I have answered your question, if you have any doubts then contact me at bit.ly/ Chat Doctor. Thanks for using Chat Doctor. Wish you a very good health. </s>
