Patient: My baby is 14 months old, since 8 months weaning has been cold, resistance is very low, the baby from four or five months to add complementary food found that the appetite is not very good, do not like to eat, and then weaning the situation has not changed, has not eaten a lot of complementary food, like milk. When the child was 13 months old, he went to check the micronutrients, other items are okay, but the blood lead is a bit too high, I do not know if 92 is considered lead poisoning, and need to be treated to reach this value? I’m not sure if 92 is considered lead poisoning, and if I need to treat it. Please give me an answer. Thank you very much! Sichuan Provincial Maternal and Child Health Hospital Pediatrics Ou Mingcai: blood lead check our normal value of 0 ~ 100, if according to this standard judgment of your child’s examination standards in the normal range, do not have to worry. Of course, there may be some difference in the laboratory judgment standard of each hospital, but the difference is generally not too big; if you are really uneasy, you can change a big general hospital to re-check or come to our hospital for checking. In addition, your child is only 14 months old, so the chances of exposure to lead-containing materials at such a young age are low, and thus the chances of lead poisoning are also low. We suggest you to find out whether there are any factors that may lead to lead poisoning from yourselves and your child’s exposure, if not, you should treat the test results correctly and not make a diagnosis based on just one test.
