Hi, no, testing Vitamin B12 right after taking a Renerve Plus injection won't give an accurate result — the injected B12 will show up in your blood and falsely raise your reading, even if your actual body stores are low.
Next Steps
Please wait at least 3-4 weeks after the last injection before getting your Vitamin B blood test done, so the report reflects your true levels. If you've only taken one injection so far, do check with the prescribing doctor about how many total doses were planned, and coordinate testing timing accordingly.
Health Tips
If you're having ongoing loose stools, it's worth getting that separately evaluated too, as prolonged diarrhea itself can affect B12/nutrient absorption.

Depends on what was your status of b12, how many inj.you took. If you have taken 5 then wait for 2 weeks before test.
