Hello

My son has been for bloods following stomach cramps, watery poop that was very pale and floaty, suspected coeliac disease. 

Anyway he had bloods yesterday and the gp called me today to say his white  blood count is abnormal, and he needs the test repeated Excatly 1 week from the 1st blood test, she said this blood test will be looked at under a microscope and will be a little diff?

So I rebooked his bloods for next Thurs, and went to Google bad mistake all I could see was leukaemia. 

I called the surgery back and they said his white blood count was 6.0 followed by 10 and a 9.

Obviously this makes no sense to me what so ever, has anyone else had to have bloods repeated, or she'd some light on this, when looking online it seems 6.0 is normal?

Thank you in advance
