Also known as Crenated RBC

Classification of RBC disorders based on the Cell Size.

Variation in shape of RBCs

Also known as Stellar cell

Rounded RBC with irregularly arranged 5-10 spicules of various length

It is seen in pernicious anemia

Triangular cells

RBC with mouth-like clear central area

Variation in hemoglobin content.

Another name for Target cell

RBC disorders are categorized according to what factors?

MCHC stands for what?

It refers to the numerical expression that corelates with the degree of anisocytosis.

Small dense RBC with few irregularly spaced projections of varying lenghts.

Spherical RBC with diminished diameter

Also know as thorn cell or spur cell

Also known as Helmet cell

Classification of RBC disorders based on the Hemoglobin Content

With MCV lesser than 80 fL

Also known as Tear Drop

crescent shaped RBC

It has 10-30 short and blunt spicules that are evenly distributed over the surface of the red cell

Have the ff characteristics: -Blue-gray coloration -Indicates young red cell or presence of reticulocytes -Increased erythropoietic activity seen in hemorrhage and hemolysis

Also known as Elliptocyte

RDW stands for what?

With no central pallor -Increased MCHC = greater than 36%

Normal value of MCHC

It is found with single or multiple vacuoles or markedly thinned areas at the periphery

With normal MCV (80-100fL)

reversibly spiculated elongated cells

Also known as pessary cell or ghost cell

RBC with just a thin rim of Hgb and a large clear central area.

Classification of RBC disorders based on the Cell Shape.

With MCV greater than 100 fL

What does MCV stands for?

Also known as Mouth cell

Normalhemoglobin, normal color Normal MCHC = 31-36%

The central pallor area exceeds 1/3 of the diameter of the cell. Decreased MCHC = less than 36%
