I just had a routine complete blood picture done. Everything is within the normal ranges however I was just comparing my previous test results and WBC count was first 8000, then increased to 11,000 and now with the latest test it is at 4940. The normal range is between 4000-10,000. The neutrophils, lymphocytes etc are all within normal ranges. So is my wbc a cause for concern? It is within the range but I've googled and now worried myself sick as it's apparently on the low end of normal. I don't have any illness or infection that I know of.
