The platelets are elevated, but not significantly so. Typically they are elevated mildly, such as 530, when the bone marrow is "revved up" to fight an infection. To fight an infection, the bone marrow works hard to make white blood cells.
If it is a viral
infection, the percent of white blood cells in the blood stream is often shifted away from the type that fight bacterial infections the best (neutrophils) to the type that fight viral infections the best, ***** ***** be lymphocytes.
If it is a bacterial infection, then the percent of white blood cells in the blood stream is usually shifted away from the type that fight viral infections the best (lymphocytes) to the type that fight bacterial infections the best, ***** ***** be neutrophils.
The blood count readings you mention suggest that the body that is fighting a bacterial infection. You don't mention the total white blood cell count (wbc). Labs may have slightly different ranges that they call "normal," but usually, white blood cell counts over 10-12 also suggest and infection.
As with every rule, there are exceptions. For example, a stressful crisis in the body, such as a seizure, can sometimes create a similar picture. Also, there are sometimes diseases of the bone marrow where it makes more of one type of cell than another, and it has nothing to do with fighting infections.
I hope this has been helpful.
