Specimen Requirements

Comments

Testing of specimens received greater than 2 hours after collection may be acceptable with the approval of the pathologist. Cells will start to decompose within 1 hour of collection. Specimen must be brought to the lab immediately (do not hold or batch multiple patients for one delivery). CSF differential (CPT 89051) will be added if indicated by cell count. Cell count will be performed on Tube #4 unless otherwise requested, or the highest numbered tube if Tube #4 is unavailable.
