I had a CBC done last Thursday and my # WBC was 5.7, normal. Went to a insta care on sat and had another CBC for a diff problem and my # WBC was 3.8 and they were concerned , said I need to see a doc to make sure there is not something wrong. Why would these #s be so diff in just 2 days? And should I be concerned? And see a doc again this week?
Hi, dairy have gone through your question. I can understand your concern. Your WBC count is slightly low.  It can be due to some viral infection. If you have any symptoms then consult your doctor and take treatment.  If you don't have any symptoms then no need to worry.  It may be subclinical infection.  Chat Doctor.  Your count will back to normal within few days. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
