MCH 25 pg — what does it mean?
Oxygen cargo per red cell
- What most labs call normal
- 27–33 pg
- Where you actually want to sit
- 28–32 pg
What this test is
The average amount of haemoglobin — the oxygen-carrying pigment — packed into each red cell.
What your number means
28–32 means fully loaded. Below 27 your cells are leaving the factory pale and under-filled, which is the classic iron picture — especially if your red cell size consistency is off at the same time. Above 33 usually travels with the oversized cells you get when B12 or folate runs low.
Why it matters
It shows whether each cell your marrow builds is fully loaded and able to carry oxygen well.
Haemoglobin is the cargo each red cell carries. When iron is short, cells roll off the line half-loaded and pale — this reading tells you how full each cell’s oxygen tank really is.
What to do about it
Read this one next to your average cell size. Light cargo plus small cells means check iron; heavy cargo plus large cells means check B12 and folate.
Where it sits in your Body Age
MCH (Mean Corpuscular Haemoglobin) is one of the tests behind Blood Renewal — How cleanly your body is building fresh blood cells, day after day. It is one of four areas that together give a single number: the age your body reads, next to the age on your birth certificate.
This page explains what a blood test measures. It is not a medical diagnosis and cannot tell you what your own result means for you — take that to a doctor.
