What it measures
The real number of the rarest white cell type.
Very little on its own; it is reported for completeness with the rest of the differential.
Why it matters for how long you stay well
It very rarely changes a decision and is read as part of the whole blood count rather than by itself.
How it shows up in daily life
The numbers are so small that you will never notice this one changing.
High and low readings
When it reads high
Usually a minor allergy signal.
When it reads low
Low is fine.
What moves it
Daily life
- allergy

Listed so a result can be read in context. It is not advice to start, stop or change any medicine; that decision belongs with your physician.
