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.
Eating, physical activity, and stress can cause an increased WBC count. The WBC count tends to be lower in the morning and higher in the late afternoon. WBC counts are age-related. I would not be concerned until the results come back and you get your results. Pregnancy is associated with increased white blood cells.
