Hi, my son 6 years old, when healthy, had bloods done, results were low ferritin, low lymphocytes 1.8, low wbcs 4.6 and low serum creatinine.

The WBC likely reflects mild suppression from a recent viral illness. The low ferritin is very common, indicating he needs more iron in his diet or a supplement.
