RBC Count
Measured in M/uL
The raw number of red blood cells. The third leg of the same stool.
What the numbers mean
These are the ranges BioForge works to. They are not the same as a lab's reference range, which is built from the general population rather than from people who feel well.
Low
<4.2
Optimal
4.5–5.5
High
>5.80
What moves RBC Count
Same drivers as hematocrit and hemoglobin. Often the first of the three to drift upward on therapy.
