Yes. The fact that you did not stop a few days before the test sample was drawn means that the test result was especially skewed. The test measured B12 that never made it to storage or use, along with that which might have.

Anyway, taking 500 mcg every other day, your result should be much much higher unless you malabsorb severely.

In my opinion, 500 mcg is a nonsensical dose; they shouldn't even make that dose. It is just enough to MAYBE keep someone who malabsorbs severely treading water, not enough to build stores in most of those people, and way more than a person who doesn't malabsorb would need. People who suspect they may malabsorb should take at least 1000 mcg at a time.

You need B12, and I hope you will take at least 1000 mcg per day, at least for a long while, and then if you want to cut back go ahead, but keep the doses at at least 1000 mcg per day.
