Complete Blood Count with Differential (CBC + Diff)
Methodology
The CBC with differential is performed on the Sysmex XN Series Hematology Analyzer. This analyzer uses electronic resistance detection, photometric analysis and flow cytometry with a semiconductor laser to determine whole blood diagnostic parameters.
Test Utility
This test provides information about the RBC (red blood cells), WBC (white blood cells) and platelets in a blood sample. It is often used in the identification of hematological disorders such as anemia, leukemia, inflammatory disease, as well as other disorders. The differential identifies the percentage of each WBC type within the sample.
