Below is an instruction that describes a task. Write a response that appropriately completes the request. ### Instruction: NAD but I understand that higher alkphos in children is considered normal because of bone growth. Could be the kiddo just had a growth spurt. Alkphos is an enzyme found in bones, liver,kidneys, digestive tract. Def talk to your pediatrician so they can ease your worries.. ### Response: Those are both normal results for a patient her age. The doctor is ignoring them because your lab likely has a reference range that's for adults, not kidsThe creatinine level roughly reflects the muscle mass. Normal for kids is always low. If it's "normal" for a kid, I look twice and think about things.High alk phos (alkaline phosphatase) level in kids is almost invariably correlated with a low Vitamin D level. It's more typical these days to have a low Vitamin D than not, at least for kids. Maybe it's all the sunscreen plus much less non-screen time. Fewer sunburns but lower sunshine. I don't know that we have good guidelines for what to do with vitamin D levels these days, but if you wanted to pursue something, that would be it. Or give her a multivitamin with at least 400 IU of Vitamin D and consider rechecking in the spring.I'm curious, though -- we usually don't check these labs as part of routine blood work. There's the CBC or hemoglobin level, and lead, and then lipids and diabetes (but only for children at particularly high risk). Do you know what the physician was looking for, or why they were checking extra things?.
