What does a low or high level of hematocrit (Hct) from a complete blood count (CBC) indicate?

ANSWER

A low score may be a sign that you have too little iron, the mineral that helps produce red blood cells. A high score could mean you’re dehydrated or have another condition. The normal range for men is between 41% and 50%. For women, the range is between 36% and 44%.
