Where does it say "abnormal lymphocytes"? That's unusual language. "Atypical" lymphocytes are seen with viral infections, classically mono. If the blood smear was the reason for referral, I would ask what the results mean. If the answer isn't clear, keep asking until you understand. They will tell you the differential diagnosis for the findings and what additional tests they recommend. There might be none.Frequent infections are the rule in childhood, not some weird immune deficiency. Is he really having fevers every single day for 3 years? Also, one of the most common findings with immune deficiencies is poor growth and your son is a tank :) Rheumatologic conditions in preschoolers often come with poor growth, rash, joint swelling, and very abnormal blood tests. But they can be more subtle and I can't say on the internet if that's a possibility in your case.
Hey yall My kiddo (3M, approx 42 pounds, 3.5 feet tall) (daily meds are nexium, senna, zyrtec, tenex, atarax, melatonin) got referred to hematology and I'm drawing a blank on what questions to ask. He had a blood smear that had "abnormal lymphocytes" and a high level of lymphocytes. He started seeing Immunology a few months ago because he's always had frequent infections and fevers just about daily for most of his life. Immunology doesn't have any diagnosis, but are thinking of referring him to rheumatology. Im just not really sure what questions to ask or what to say really. If there's a better sub for this, please point me in the right direction. Thanks y'all!
