That's a good question. I can imagine that there was a time before there was life on Earth, and then clearly there was a time X-hundred thousand years or a million years later when there were things that we would all recognize as biological.
A high count indicates the presence of inflammation in the body. Because white blood cells are calculated by the number of cells per volume of blood, test results can vary between labs. Different labs use different degrees of measurements for the white blood cell count.
It might be time to get a new doctor then....although I think that a high white blood cell count is usually caused by infection or something along those lines. Some info from the Mayo Clinic: White blood cells (leukocytes) help fight infection in your body.
