RBC

Also known as: Red Blood Cells, Erythrocytes

What it means

The count of your red blood cells (millions per µL). Low RBC often points to anaemia; high RBC can point to dehydration or other issues.

Typical normal range

Men: 4.5–5.9 million/µL · Women: 4.0–5.2 million/µL

Reference ranges vary by lab, age, sex, and pregnancy. Always check the range on your own report.
