A technician needs to calculate the absolute value of neutrophils on a blood smear. The neutrophil percentage on the relative white blood cell count is 78%, and the total WBC count is 6.0 x 109/L. Remember you need to convert 6.0 x 109/L to mcl or mm3 first. What is the absolute value of neutrophils for this patient?
4580 neutrophils/mm3
4600 neutrophils/mm3
4680 neutrophils/mm3
4700 neutrophils/mm3
We complete a manual WBC differential to check the automated values that are out of the normal range for each type of white blood cell.
We count 150 WBC's for a manual differential.
The monolayer or "Area of Even Distribution" is usually a distance of one 10x field behind the feathered edge and is the optimal area for examination of cells, because it dries quickly and cells are well spread (not overlapping) and not disrupted.
Neutrophils are part of the innate immune system and are the first line of (and are essential for) defense against bacterial pathogens.
Bone marrow is responding to the loss of blood in regenerative anemia.
What is nonregenerative anemia?
Bone marrow is unable to respond to blood loss
Bone marrow produces excess red blood cells
Blood clots excessively
Blood pressure increases rapidly

present
absent
increased
