Heya so I called the Dr's the other day as my son at 9 has been waking every night the past few weeks running to the toilet and quite a bit through the day so he give me a appointment today to get blood test but my son has special needs and is non vebal so he couldn't do it so needs to do a referral but was able to do a finger prick test and it was sitting at 7.9 and he ask did he have something to eat before coming in I said no he just had lunch at school he said was just above normal and will see what bloods say but am just worrying and was wondering is 7.9 OK for a prick test
