I’m really confused about my blood results...

I had injections of B12 last August to try boost my levels. They then tested it again last week and I just had a text to tell me the results...

They text to say my folic acid levels were low? And that they were going to prescribe me folic acid that I need to take for at least 3 months.

They didn’t specify whether folic acid is the same as B12, or iron? Because that’s what I’ve been deficient in, in the past? And that’s what I thought they were testing for.

I’m going to ring tomorrow and ask but want to check whether anyone can clarify, as google is confusing me 😂
