After paying for doctor visits for nervous shaking that i have.The Doctor advised me to take b12 test and i did it.I got the value as 261 and doctor says that it is low as per my age (25 years),advised me a couple of injections(nuerobeon ) and pills to take.But the report says that it is normal.Normal range is between 200 to 800.Please advise whether the information is right or not.Thanks in advance
Hi, Thank you for posting your query. The normal range written in the lab report papers mention a value of 200-800 for normal vitamin B 12 level, as you have mentioned.  However, for the nervous system to function properly, it should be at least more than 450. So, your vitamin B 12 value is low, but not very low. Hence, you require treatment as advised by your neurologist. I hope it clarifies. Wishing you good health, Chat Doctor.
