Hi Denise. The neck screening means to check whether the person is prone to develop insulin resistance leading to type 2 diabetes mellitus. They look for presence of thickened, dark, velvety skin folds/ patches around the neck and if they are present in the kids then they advise them to undergo confirmatory blood test called Oral Glucose Tolerance Test (OGTT) and HbA1c. They also want to know how the lipid profile of the kid is for managing risk factors of related cardiovascular disease. So please go ahead and get your daughter tested for diabetes. This will throw a light where she stands and if not having diabetes at this stage you can very well help her reduce the chances of developing diabetes in near future by so many lifestly measures. Do not delay.
