While yes, it is possible to have a slightly high count without any cause of concern, it is best to rule out certain conditions which can slightly raise the WBC count due to inflammation. These conditions are
stress—physical or emotional, rheumatoid arthritis,
osteoarthritis, thyroid disorders, IBS, Crohn's, celiac, food intolerance, insertion of an IUD (in women), food intolerance, anemia, allergy, dermatitis etc. Do discuss this with your doctor. Take care!
