Describe the characteristics of a regenerative left shift
|
leukocytosis, neutrophilia and a left shift a.k.a. segmented neutrophils will be greater in number than bands or immature wbc

Describe the characteristics of degenerative left shift
|
the neutrophil pattern is normal to decreased but with a left shift in which concentration of bands (immature wbc) will be greater than segmented neutrophils (Indicates max release from bone marrow in response to inflammation and signifies presence of acute severe lesion) |
