A member asked:

Is there any possibility an anemia test cbc could be negative if i have very slight blood in stool? i feel very weak but cbc turned up negative

Yes: The important thing is the reason for the blood in the stool. That may be the underlying cause of your "weakness". It takes a lot of blood loss to cause anemia.
