Low RDW (Red Cell Distribution Width) may be caused by conditions that result in a narrow range of red blood cell sizes. This can occur in conditions such as iron deficiency anaemia, thalassemia, or chronic diseases with stable red blood cell populations.

RDW Blood Test: What It Is, Procedure and Results

Q: When would an RDW blood test be needed?

RDW blood tests may be requested when a healthcare provider suspects or wants to monitor certain medical conditions. It can help diagnose and manage anaemia, as different types of anaemia can cause variations in red blood cell size.

Q: Why is RDW high in iron deficiency anaemia?

In iron deficiency anaemia, the body lacks sufficient iron to produce haemoglobin, leading to smaller and larger red blood cells. This variation increases RDW (Red Cell Distribution Width) levels, indicating the range of cell sizes.

Q: What level of RDW is dangerous?

Abnormal RDW values alone are not immediately dangerous but may indicate anaemia or other blood disorders that need further evaluation.
