Red Cell Indices
The size and hemoglobin content of your average red blood cell. These are what tell your clinician why a blood count is off, not just that it is.
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.
What moves Red Cell Indices
Small cells usually mean iron deficiency or chronic blood loss — relevant if you are donating blood to manage hematocrit. Large cells usually mean low B12 or folate, alcohol, or an underactive thyroid. Rising MCV on therapy with phlebotomy is worth checking against ferritin.
