Hi Melanie, thank you for your question to the forum.
The normal range for blood glucose levels (BGLs) is between 3.5–7.5 mmol/L, however there can be a difference between blood taken from a finger prick and that taken via a formal blood test with blood taken from the arm. Care also needs to be taken in interpreting finger prick BGLs as sticky fingers or dirty hands can affect the result. It’s also important to make sure that the test strips are in date and meter calibrated properly, as this will affect the accuracy of the reading.
A high BGL can indicate type 1 or type 2 diabetes, however a correct diagnosis is essential. Weight gain is more closely associated with type 2 diabetes, however type 1 diabetes can still occur in children who are carrying too much weight. Refer to the link below for more information about the different types of diabetes.
It’s important to be aware of other symptoms of diabetes which include thirst, excessive urination, tiredness and blurred vision. In type 1 diabetes these symptoms can develop rapidly and may also include weight loss and tummy pain, in this case immediate medical assistance should be sought. In type 2 diabetes, a person may have more subtle or possibly no symptoms, however correct diagnosis’ and treatment are still important.
We would advise you to see your GP immediately. He or she will check your daughters BGL and urine for ketones and if these are abnormal you should be referred to a paediatric diabetes team. However, if type 2 diabetes is suspected, they will send your daughter for a glucose tolerance test. In either case, treatment should be initiated straight away.
While it is possible that the original BGL was not accurate, it’s important to seek medical advice so that you know either way.
