HCT and Hb

Updated 3 months ago by Michelle Pool


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

We run the Hematocrit (HCT) numbers 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

Should I be concerned if my Keto-Mojo meter suggests mine is low?

Plainly put, no, you should not be concerned. But if you are, you should reference another testing source.

Unlike meters designed to calculate HCT for diagnostic purposes, our meter uses the Hematocrit (HCT) number in order to get a more accurate reading of your blood glucose; by using this additional calculation, the meter achieves an industry-leading standard of accuracy. However, the HCT results may not be a true reflection of your HCT level.

If you are concerned about anemia or erythrocytosis or simply want a reliable HCT reading, you should find and take a test that's designed to provide you with HCT readings or consult with your physician.


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.

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.
