A recent blood test reported very high levels of Vitamin B12. It was 1346 pg/ml (normal 180-914pg/ml). We are trying to figure out the cause. 2 weeks before this blood test she was admitted at a hospital because of high fever. And was given Neurobian Forte injection. Could that be the cause for spike in Vit B12?
