| I have had this twice now. My other liver function indicators are normal, my B12 is low but not insanely so. Dr doesn't seem overly concerned but I am a little concerned... |

| I have had one or two points over the top of the range several times - doctor has never even mentioned it. |

| Slightly high probably not a concern. But high MCV is an indicator of macrocytic anemia which can be caused by low B12. |

| How low is the B12? It is likely that. Are you vegan? Gastric bypass? You can start a B12 supplement and see if the MCV normalizes. It is actually high normal now. |

| High alcohol intake causes elevated MCV. How much do you drink? |

| B12 above 300 is normal. As above, alcohol can also increase size of red blood cells. |

Op - no I went through this with my dr and he said the amount I drink plus the other lab results indicate it’s not that |

| You can stop drinking for 3 months and recheck and see if it’s actually that |

You can have symptoms of B12 deficiency at 367. In Japan the normal cutoff is 500. |

| OP did not mention symptoms- only MCV. |
