Detailed Answer:
Hello sir and welcome.

Thank you for writing to us.

I have gone through your query with diligence and would like you to know that I am here to help. Taking the multivitamins will not drastically change your folate and vitamin B12 levels. So you need not discontinue them, but you can choose to skip taking them just 1 day before testing and that shall more than suffice sir.

I hope you find my response helpful. Please feel free to write back to me for any further clarifications, I am always here to help.

Best wishes.
