What is the difference between RBC count and hematocrit? All the explanations I am finding online say that the difference is that the former is the number of cells, and the latter is the percentage of cells. But that tells me nothing: The number of cells is only meaningful if you know exactly how much blood was drawn, which means it is a proportion. A proportion is a percentage, and that's exactly what people say hematocrit is. So I come straight back to zero.
Dear Fukuoka-musician: I was also searching for the answer. After viewing some explanation both in paper and online, here is what I come up with : 1. RBC count (Red blood cell count) : it is the number of RBCs in a cubic millimeter of blood. RBCs are the cells produced in the bone marrow that carry oxygen to tissues. A person with significantly low RBC count can feel fatigue, SOB and appear pale in skin color. A decrease in RBC count usually caused a decrease in the hemoglobin and hematocrit values. This usually implies the underlying condition of having anemia. 2. Hemoglobin (Hb): Oxygen is carried to the tissues via hemoglobin in the RBC. Any drug which causes a suppression of the bone marrow, will decrease the hemoglobin level. What is the test of Hb all about? The hemoglobin concentration is the amount of hemoglobin per unit volume. The normal value of adult male hemoglobin is 13.0~18.0 gm/dl, and that of female is 11.0~16.0 gm/dl. When the value has significantly decreased, it can be the indication of anemia. 3. Hematocrit: It is the % of the cellular component in the blood to the blood plasma (or the fluid). The test is one of the truest markers of Anemia. A decrease in the value of Hematocrit is always seen with a decrease in the hemoglobin. To summarize both RBC counts and Hematocrit tests are to reflect the state of red blood cells in the body. Hemoglobin is to measure the actual mass of hemoglobin protein per unit of the blood. Hematocrit is the proportional red blood cell in relation to the rest of blood components. Both are used to diagnose anemia.
So if your Hematocrit is lower then it should be when “hemoglobin x 3” is applied that means your over hydrated?? If so what effects would that cause the person to feel?
Yeah...well...13.8 x 3 doesn't equal 44.3. In that instance my Hct should be 41.4. I guess this explains an MCHC of 31. By the rule of 3s...my 4.9 RBC should equal Hb of 14.7. 13.8 ain't 14.7. As a 12 - 15hr/wk cyclist, this is causing some "problems". No dehydration here either...at least not the morning of the test.
This was the most helpful video I've watched on the topic. It's hard for me to nail down anemia vs dehydration on the blood labs
We need professors like you Sir.
I need the link to the full lecture sir. Thank you
bless you sir

If the RBC is 4. What is the Hgb?
Hey sir can I please email you about my labs. I been stressing so bad over it
What about if it’s the opposite and too low
Yeah...well...13.8 x 3 doesn't equal 44.3. In that instance my Hct should be 41.4. I guess this explains an MCHC of 31. By the rule of 3s...my 4.9 RBC should equal Hb of 14.7. 13.8 ain't 14.7.

Very helpful
Glad you think so!
thankyou love from pakistan
My H&H is dropping steadily but my RBC is normal
