Sedimentation Rate (ESR)
How fast red cells settle in a tube — an old, inexpensive, non-specific measure of inflammation. It moves slowly over weeks, so it complements hs-CRP rather than repeating it.
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 Sedimentation Rate (ESR)
Rises with infection, autoimmune disease, anemia, kidney disease, pregnancy, and simply with age. Falls when red cells are crowded — which matters here, because testosterone therapy raises hematocrit and can mask a real inflammatory signal.
