I am glad however that your physician didn't go down the rabbit hole with that report. Low WBC's could be anything from a simple viral illness, certain bacterial illnesses , to low B12 or something more dangerous like leukemias. For eg: We would see a lot of low WBC's in Covid. B12 though can lead to serious complications if not corrected promptly. And it is required to correct these before you jump to more sinister diagnoses Your second consultant gave you a simple test with basic medications to treat it . Commenting on the basis of what information you have put forth.

That is why, we have a range of values which we call normal. It is never one fixed value. There may be deviants but it is rare.
