Reticulocyte Count
Brand-new red cells, still maturing. Shows how fast your bone marrow is producing — the production side of the hematocrit picture.
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 Reticulocyte Count
Rises after blood loss, therapeutic phlebotomy, or when testosterone is driving red cell production hard. Falls with iron, B12 or folate deficiency, or with kidney disease. Useful for telling a marrow problem apart from a supply problem.
