Hi,

Thanks for your query.

Your child is probably being tested for metabolic problems, that are in-born biochemical errors in our body systems. several such diseases only manifest during such stress, may it be a disease. so better get investigated.

The fasting blood glucose level, which is measured after a fast of 6 to 8 hours, is the most commonly used indication of overall glucose homeostasis( natural balance mechanism ), largely because disturbing events such as food intake are avoided.

Hope I have answered your query. If you have any follow up queries I will be available to answer them.

Regards,
