33
Q

Tend to be large (up to 6 um) and often accompanied by toxic granulation induced by either bacteria or fungi are suggestive of sepsis

A

34
Q

water has been lost and the chromatin becomes dense and -dark

PYKNOTIC AND NECROTIC CELLS

35
Q

i in neutrophils generally indicate imminent cell death In a pyknotic nucleus

A

pyknotic nuclei

36
Q

-Increased numbers of pyknotic or necrotic cells suggest that an

A

extended amount of time has elapsed between blood collection and blood film preparation

37
Q

-Necrotic nuclei are found in

A

dead neutrophils/necrobiotic neutrophils; they are rounded nuclear fragments with no filaments and no chromatin pattern

38
Q

-Is a result of osmotic swelling of the cytoplasm or by increased adhesion to the glass slide in stimulated neutrophils

A

CYTOPLASMIC SWELLING

39
Q

-Regardless of the cause, the result is a variation in neutrophil size or neutrophil anisocytosis

A
