What is Hematocrit (Hematocrit)?
Hematocrit is measured as part of a complete blood count (cbc) panel. Your hematocrit is normal — the proportion of red blood cells in your blood is healthy.
What does a high Hematocrit mean?
Your hematocrit is elevated, which can indicate dehydration or other conditions causing blood thickening.
If markedly elevated: Your hematocrit is critically high, increasing risk of blood clots. Please seek medical advice.
What does a low Hematocrit mean?
Your hematocrit is low, indicating fewer red blood cells than normal. This often accompanies low hemoglobin and may suggest anemia.
If markedly low: Your hematocrit is critically low, meaning a very small proportion of your blood is made up of red blood cells. This is a serious form of anemia that needs prompt medical attention.
