White blood cells (leukocytes) are produced in the bone marrow and operate as part of the body’s immune system.
It is normal for WBC levels to sometimes fluctuate. Therefore they can fall into the low-end or high-end on some days. If you receive abnormally low or high test results, make sure to re-do the test to see if levels have fallen into place since the first one.
For maximal accuracy, combine this test with:
- Red blood cell count.
- Blood platelet count.
If results show low white blood cell count, consider bone marrow.
If results show elevated white blood cell count, consider systemic bodily acidosis causing damage to cells.
