Below is an instruction that describes a task. Write a response that appropriately completes the request. ### Instruction: low neutrophils high lymphocytes pediatricMy son is 3 years old. Got a ton of blood work for his weight I guess. He's 27lbs. He has high energy and no concerns other than occasional constipation. The blood work came back with low neutrophils 21% and high lymphocytes 71% (which has me sick to my stomach thanks to Google. WBC, RBC and hemoglobin is normal. Hematocrit is low 32.9% with the range min of 34%. His neutrophils absolute is 1.56 which is in range but on the low end of the range that says the min is 1.50. Lymphocytes absolute is in range. All morphology is normal. His ferritin is low at 23 with the standard low being 36. Everything else is normal. They did a lipid panel which I didn't have him fast as no one informed me. And his triglycerides were pretty high at 238mg/dl. He had half a sugar cookie an hour before and I was feeding the other half during his blood draw to distract him. VLDL was high at 48mg. Everything was normal on lipid. Carbon dioxide was low at 17.0mm.. ### Response: First off keep in mind the percentages always have to add up to 100. So either the neutrophils are low because the lymphocytes are high, or the lymphocytes look high because the neutrophils are low. So he's got one problem, not two. Based on the other values my guess is that it's probably the low neutrophils but I'd have to see the absolute numbers.His iron is a little low but otherwise everything else is normal. Do you have a hard time getting him to eat meat? Because it's likely just dietary.In general, I really recommend against googling labs because it always comes up with scary stuff. Those aren't cancer values if that's what you're worried about. Could be he's fighting off an infection, could be related to a malabsorption issue or dietary deficiency, could just be normal for him.If it were my patient or my child I would think it's not likely a big deal, but would want to recheck at some point in the next few months to see if it changes. Keeping in mind I'm a family doctor and not a pediatrician, so they may have a slightly different plan..
