HCT and Hb, What do they mean?

Updated 1 month ago by Michelle Pool

Generally speaking, Hematocrit (HCT) is the volume percentage of red blood cells in the blood.   

Hb stands for Hemoglobin, which is the protein molecule in red blood cells that carries oxygen from the lungs to the body's tissues and returns carbon dioxide from the tissues back to the lungs.
A low hemoglobin level is referred to as anemia or low red blood count. 

Hb is essentially used as a measure of how much oxygen you are able to carry in your red blood cells in the context of measuring, using the Keto-Mojo device.

It should not be used for the diagnosis of anemia or erythrocytosis.

We use the Hematocrit (HCT) and Hemoglobin (HB)  numbers and run that through an algorithm with the Blood Glucose (BG) so we can get a tighter accuracy on the Blood Glucose. 

The test for hematocrit (HCT) as part of the system, is intended for use in the in vitro quantification of packed red blood cell volume fraction in capillary whole blood as an aid in monitoring the status of the total volume of red blood cells. The test reading of hematocrit (HCT) is used only to determine whether the blood test sample is within the acceptable range of β-ketone & blood glucose monitoring system monitoring system. It should not be used for the diagnosis of anemia or erythrocytosis.

By using the additional calculation we can achieve an industry leading accuracy standard of deviation of only 5mg/dl under 100mg/dl or 5%. The FDA standard is that you can be out by 20% and still be approved, this is what you find with many other meters

However there is a tradeoff here, we have found that the HCT fluctuates and moves around a lot depending on many factors which causes confusion for some.

The meters primary focus and its FDA clearance for accuracy are for Ketones and Glucose, the H & H is for calculation purposes and should not be used as a diagnostic tool. In the next generation meter, I will bury those numbers.

How did we do?
