Question: 7 months old kid with high Lymphocyte

 s_b_nayak - Mon Jan 19, 2009 3:38 am


My kid (7 month old) has inadequate growth (right now weight is 6.3kg, last 4 months weight gain is 2kg). He doesn’t have any other abnormalities apart from he has less appetite.

We have examined his blood and here is the result:
Haemoglobin: 12.5gm/dl
WBC: 14200/cumm
Differential count: Neutrophils: 22%
Lymphocytes: 74%
Monocytes : 01%
Eosinophils : 03%
Basophils : 00%
Peripheral smear: RBC = Predominantly Normocytic, normochromic
Platelets = Adequate
WBC = No Abnormal cell seen

Please suggest me what the test indicates? We are a bit worried about WBC and Lymphocyte counts. Are the quantities of WBC, Lymphocytes and Neutrophils falling in normal range?

User avatar Hello --

While your child would seem to be suffering from a mild "failure to thrive" situation, and while the bloodwork probably does indicate something is wrong, it's dificult to narrow it down more.

Hemoglobin is marginally low. White count is elevated, but not as in an actute bacterial infection, although it is close to that range. No abnormal cells, adequate platelets. This all is suggestive of either a low-grade infection or perhaps some sort of anemia, perhaps due to an abnormality of the bone marrow (although this is far from clear based on the results provided).

Probably the best course is to follow this for a while and see if it resolves (as an infection) or if the abnormalities can be correlated with a marrow or other sort of disorder, or perhaps a metabolic disease. It is extremely difficult, at this distance, to hazard a more precise guess, and the child really does need to be followed up to determine why he is slightly under the norm in terms of growth and has slightly abnormal bloodwork.

I hope this is helpful. Good luck to you. Please follow up with us as needed.
