What could my sons blood counts mean@?

My 13 yr old has been suffering from nausea (mild to mod) for over 3 months. His blood work show normal except for Lymph% 53 Lymph 62 Mono 3 (dropped from 5 1 wk earlier), mono% 11
EOS 12 (up from 3 the previous wk) Mono% 11 Seg went from 38 to 27 and grn% went from 38-27. His WBC is normal. he has been tested for giardia antigen and ova+parasites...both neg. they are presently retesting him All foods make his nausea worse, and it seems to be getting worse and I don't know what to do for the nausea while awaiting test results. Any ideas would be helpful.

Take care of the diet,if he is not having any problem ( Health )

Lymphocytes increase with both chronic and viral infection. Monocytes are the 2nd line of defense (neutrophils are first line) against bacterial infections and foreign substances. Neutrophils decrease with viral disease and some other things I'd rather not mention at this point. If the segs (matures neutros) went down, I would expect the banded neutros (immature neutros) to go up. Bands multiply quickly in acute infection. I don't recognize "grn%". Is this supposed to granulocytes? These are just neutrophils, basophils and eosinophils.

Eosinophils increase with, among other things, parisitic infection. Hence the O&P and Giardia antigen tests.

His overall granulocytes have decreased. 38-27. Basophils decrease with stress and hypersensitivity, and eosinophils decrease with stress and adrenocortical hyperfunction. Don't worry about adrenocortical function now. If he had a metabolic panel (also called a chem 7 or chem 12), do you have those results?

While I cannot offer a diagnosis (outside my scope of practice), perhaps I can help with the nausea and vomiting until I know more. Keep him on bland foods and toast/crackers, small more frequent meals. No liquids or only a small amount with meals. In between meals, small and frequent sips of water. He should remain quiet for one hour after meals. Check with his doctor about the use of Reglan or Compazine for the nausea. Compazine can be given rectally by suppository. Ask also about the possiblity of having an EGD (esophagogastroduadenoscopy). This endoscopy can examine his esophagus, stomach and the first portion of the small intestine.

eosinophils indicate allergy or parasitic problems. Also ova/parasite tests (not that is is what your son has for sure), but they should do more than one. There may be some days were worms are not shedding eggs and thus the test would be negative.
Demand more testing until the answer is found
good luck
