Red Cell Distribution Width (RDW)
Variation in red blood cell size. It helps classify anaemia and has been associated with outcomes in several populations, but it is a non-specific marker and not a measure of biological age.
What is measured?
The level, concentration or activity of this biomarker measured in the relevant blood sample.
What the result represents?
Aden's range
What a raised or a low result can indicate
How Aden reads it as part of a system?
Aden reads this result alongside haemoglobin, MCV, MCH, MCHC, ferritin, iron and your previous measurements. It is treated as one part of the wider cellular picture, not as a diagnosis on its own.
What changes between tests?
Which related markers give it context?
haemoglobin, MCV, MCH, MCHC, ferritin, iron
