One type of white blood cells low

[Mummy2both1991]

My DD had to go have bloods done due to on going stomach pains (we are thinking allergies)
Any way the other week she got blood done for thyroid,kidney and liver function, the doctor rang last Thursday to thyroid,kidney and liver test where great and started asking was DD sick (shes never ill) I said no she's been great and she went onto say one type of her white blood cells where low and wanted them repeated. She had them done Wednesday there and I got a text from GP (different doctor )saying they are still low but the GP who's been dealing with it is going to ring me for continuity.

My heads racing worried sick anyone else experienced this

This is a really common incidental finding - it depends a little bit which type of cell is low and anything findings but usually all that's needed is a review of the history and a repeat test at a longer interval (may not even this, it's quite common for children's blood tests to be flagged as abnormal when they actually aren't, and someone needs to look up the age specific reference ranges).
