Hello,

Welcome to icliniq.com.

Kindly provide me any other clinical complaint if you have. Kindly mention whether you have taken any vitamin B12 supplement or tablet or injection? Attach your all reports to give more comment. Usually, liver disease, kidney disease, B12 intake, myeloproliferative neoplasm are among the causes for high B12. Take care.

Patient's Query

Thank you doctor,

I was admitted to the hospital before 10 days for hangover and alcohol de-addiction. Currently, I am taking Nexpro 40 mg, Febuget 40 mg, Astin 20 mg.

Hi,

Welcome back to icliniq.com.

Your B12 is high as per the report (attachment removed to protect patient identity), but myeloproliferative neoplasm seems very unlikely in your case, as total count, Hb (hemoglobin), and PCV (packed cell volume) are within range.

Secondly, liver and kidney profile results were also not altered much. During the hospital stay, you might be given B12 injections that can lead to a high B12 level. Repeat your serum B12 after 15 to 20 days. Do not worry; if it is still high, then further workup will be done.

Take care.
