Can someone please help talk me down. I've been feeling tired lately, so went privately and got a whole host of bloods done. All came back normal except ESR which is 15 (range 0-12). Should I be worried? And what could this mean? If anyone is familiar with interpreting blood results, should I follow up with my GP on this? FbC, thyroid, biochem, all normal. I don't feel under the weather though so not sure why it's indicating inflammation unless it's something worse?
