<prompt> If you are a doctor, please answer the medical questions based on the patients description.I m 28 weeks pregnant. I just found out that I failed my glucose test. The blood test said my RBC and Hemoglobin are low. My MCV and MCH are high. What does this mean? Also, I have to have another ultrasound to check the valves in the umbilical cord. Should I be concerned?  <response>: Hi, Low He and high MCV is known as megaloblastic anemia. You get this when you are deficient in B complex vitamins B12 and folic acid. I strongly suggest you to start folic acid 5 mg tablets along with a multivitamin till you deliver as deficiencies can impair babies growth. Your second question:No need to be concerned about scheduled ultrasound. It is to check that your baby is fine. Hope this helps.
