Below is an instruction that describes a task. Write a response that appropriately completes the request. ### Instruction: Thank you for your answer. I called the gp to talk about the results until I see her next week. Shes telling me results are ok and should not be worried at all. She is actually telling me that low reading of alk phosphatase and Alt is no concern and would have been a problem if it was high.I kept insisting by telling her that it must be a reason for these to be low. She did not know what to say.I will insist for a referral anyway which will take months? but should i be asking for another set of blood tests in the meantime but this time to check magnesium, zinc and b6 or b12? Could this be a cause for his pains?. ### Response: High levels can indicate liver or bone issues, yes, but low levels could still warrant further investigation, especially if your child is experiencing ongoing pain.Nutrient deficiencies, while they can cause muscle and joint pain, are only one of many potential causes.
