RDW (Red Cell Distribution Width)

RDW measures how much your red blood cells vary in size. A higher RDW can be an early sign of low iron, B12, or folate, and is linked with overall health and aging.

BioSocial Community Benchmark
RDW (Red Cell Distribution Width) · BioSocial community, using one latest reading per person.
| Metric | Community | You |
|---|---|---|
| Latest reading | 12.9 % | — |
| In the optimal range | 100% | — |
| 6-month change | — | — |
| Members with readings | 1 | — |
| Latest median | 12.9 % | — |
| Members with repeat readings (6 months) | — | — |
The 6-month trend averages each member’s percentage change between their first and latest readings in that period. More members and repeat readings will make these early numbers more insightful.

Practices Moving RDW (Red Cell Distribution Width)
Observed readings among members currently tracking each health practice.
| Health practice | Members with readings | Latest average | Average change |
|---|---|---|---|
| Alcohol Reduction | — | Not enough readings | Not enough repeat readings |
| Folic Acid | — | Not enough readings | Not enough repeat readings |
| Iron Supplementation | — | Not enough readings | Not enough repeat readings |
| Vitamin B12 Supplementation | — | Not enough readings | Not enough repeat readings |
Change compares each member’s first and latest readings since their current practice start, including readings up to 24 hours before starting. Members may track several practices, so these are associations—not proof a practice caused a change. Arrows show direction, not whether a change is healthy. Only % readings are included; contributor identities are not shown.
