Tell me, is anyone who has had blood tests? What should be the norms for Folate, B12, iron and ferritin? One says only anemia, the second says both folate and B12 need to be raised. I know that ferritin is normal at 70 and above, and iron is 15. The child is 1.3 years old. My ferritin is 53, hemoglobin is 126. The gynecologist said excellent indicators, the pediatrician today asked about my blood test results and says they're also low. Thank you in advance.
