Test Code LAB209 CELL COUNT, FLUID

Important Note

Deliver sample to laboratory immediately.
This test is subject to reflex testing, see Laboratory Reflex Testing Policy, you have the option to decline reflex testing if you believe it is not medically necessary. If any nucleated cells are present, a differential (CPT: 89051) will be performed.

When there are less than 50 cells available to count on the differential smears, we will not be reporting out the percentage of cell types or absolute counts as the accuracy and reliability of the differential is low.  A comment will be entered that states the number of cells counted and the cells that are present.  The charge for the differential will be credited.
