Brief Answer:
Generally hemoglobin on 7
Detailed Answer:
Hi there,
I've seen people as low as a hemoglobin of 3. The normal should be above at least 13.5. Complications generally start around 7 so we recommend everyone who is anemic get transfused once levels get to 7. That is of course if you are a health person without medical problems. If there is underlying heart disease, then we transfuse earlier.
I hope this helps.
