RBC disorders are categorized according to what factors?

RDW stands for what?

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

Variation in size of red cells

Variation in shape of RBCs

Variation in hemoglobin content.

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

What does MCV stands for?

Classification of RBC disorders based on the Cell Size.

With normal MCV (80-100fL)

With MCV lesser than 80 fL

With MCV greater than 100 fL

Classification of RBC disorders based on the Cell Shape.

Classification of RBC disorders based on the Hemoglobin Content

Also known as Crenated RBC

Also know as thorn cell or spur cell

Also known as Elliptocyte

Also known as Helmet cell

Also known as Mouth cell

Also known as Stellar cell

Also known as Tear Drop

Another name for Target cell

Also known as pessary cell or ghost cell

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

reversibly spiculated elongated cells

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

It is seen in pernicious anemia

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

Triangular cells

crescent shaped RBC

Spherical RBC with diminished diameter

RBC with mouth-like clear central area

Fragmenting or disintegrating RBC

MCHC stands for what?

Normalhemoglobin, normal color Normal MCHC = 31-36%

Normal value of MCHC

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

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

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

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