Customer Question

I had blood work done. What does mono Auto mean? It says its 4.2 L

MONO is short for Monocytes, one of the subtypes of Leukocytes [which are the White Blood Cells which comprise you immune system.

see link:

AUTO means the % of monocytes was ESTIMATED by an Auto-mated cell counter machine.

While 4.2% is technically Low [hence the "L"] (usually Normal is between 4.5-9 or so), it is still considered in acceptable range [of 4-10].

I see no cause for concern.

Take care.
