<s>[INST] I have just been told my son who is 12 years old has a iron level of 18.0. This is the second time. He has just come off a 3 month course of iron, with no change and then this count. The doctor has just put him back on the same tablets. Do you think i need to have further tests done? [/INST] I just saw your query. If the iron levels are getting down again and again then I would strongly suggest  you to get his haemogram done.  This blood test will help us to know why the iron levEl is getting low in body. Also try to see  if he is experiencing any kind of bleeding from his body..may be it can be with stools, urine, any tooth infection,  nose bleeding etc.I hope this helps.Thanks </s>
