> 21 years 1.8-6.8 1.0-3.4 0.2-0.8 0.0-0.4 0.0-0.1 < 0.1
Critical value Neutrophils ≤ 1.0 x109/L

Note: Neutrophil counts ≤ 1.0 x109/L are not called if a prior critical was reported in the preceding 24 hours
Synonyms Eosnophil; Basophil; Neutrophiil; Granulocyte; Monocyte; Lymphocyte; Immature granulocyte; Leukocyte differential; WBC differential
Turn around times Stat 1 hour, Routine 4 hours

Note: STAT differential turnaround time of greater than 1 hour may be seen if manual review of a sample is required
Additional information All differential counts are routinely performed by automated flow cytometry.

Neutrophil Absolute Count (Total ANC) includes segmented neutrophils and bands. Immature granulocytes/left shift includes metamyelocytes and myelocytes

A manual differential will be initiated by the laboratory at a separate charge if an automated differential is technically inadequate for the analysis of a particular sample.

Manual differentials also include RBC morphology and platelet morphology.
