# What does a low MCHC mean?

> Low MCHC (hypochromia) means red cells are pale — less hemoglobin per unit of volume. It is a feature of iron deficiency and thalassemia, and can accompany anemia of chronic disease and lead exposure. It is read with MCV and MCH; ferritin decides whether iron is the answer.


## What is the normal range for MCHC?

- age 18+: 32.0 – 36.0 g/dL



## What are the common causes of low MCHC?

1. Iron deficiency
2. Thalassemia trait or disease
3. Anemia of chronic disease
4. Lead poisoning, sideroblastic anemia (rare)

## What symptoms go with low MCHC?

- Fatigue, breathlessness, pallor if anemic

## What do clinicians usually check next?

- Ferritin, iron studies, CRP
- Hemoglobin electrophoresis when ferritin is normal
- Source of iron loss when deficient

## Common questions

### What is the difference between MCH and MCHC?

MCH is hemoglobin per cell; MCHC is hemoglobin per unit of cell volume (concentration). Both fall in iron deficiency; MCHC rises in spherocytosis where cells shrink but keep their hemoglobin.
