Haematocrit
What It Is
Haematocrit measures the proportion of your blood volume that is occupied by red blood cells.
Why It Matters
It helps assess anaemia, dehydration, and blood disorders.
If Levels Are High
Elevated haematocrit may indicate dehydration, polycythaemia, or chronic lung disease.
If Levels Are Low
Low haematocrit suggests anaemia or fluid overload.
Preparation
No special preparation required.
How Often to Test
As part of a full blood count, typically annually.
