Typical symptoms that prompt a CBC include fatigue, weakness, pallor (suspected anemia), signs of infection (elevated white blood cells), or bleeding tendency (low platelets). Since the context lacks specific data on this topic, this answer is based on common medical knowledge, not on the provided sources. The evidence level is 'practice'.
