An antithetical relationship exists between the antigens M and N. Antithetical relationships occur in situations where for a given locus, only one of two genes may be inherited, the alleles are termed antithetical alleles.
In immunohematology, an antithetical relationship exists between M antigen and which of these antigens?

A. K

B. S

C. Vw

D. N

The cells indicated by the arrows in the image are spherocytes. Spherocytes have a decreased surface to volume ratio and are therefore smaller with an increased MCHC. Spherocytes have lost their bi-concave shape and are spherical in shape, hence the name. What are the cells that are indicated by the arrows in this peripheral blood smear image?

A. Echinocytes

B. Elliptocytes

C. Spherocytes

D. Stomatocytes

Serum separator tubes should not be used for:

A. blood bank tests

B. therapeutic drug tests

C. serology tests

D. all of the above

The image shown in this question is depicting a rosette formation. Here the red blood cells are surrounding and adhering to the outside of the white blood cell.

A. Rouleau formation

B. Cold agglutination

C. Rosette formation

D. Monocyte activation

Skeletal deformations result from the increased erythropoiesis that occurs in beta thalassemia major. Children with beta thalassemia intermedia may demonstrate some facial bone deformity, however this is not common. Beta thalassemia minor rarely causes any physical signs or symptoms and beta thalassemia minima is completely asymptomatic. Skeletal deformations are most commonly present in which of the following beta thalassemias?

A. Beta thalassemia minor

B. Beta thalassemia intermedia

C. Beta thalassemia major

D. None of the beta thalassemias

E. All of the beta thalassemias equally

Convert the following temperature from Celsius to Fahrenheit 8 degrees C

A. 77 degrees F

B. 68 degrees F

C. 46.4 degrees F

D. 14 degrees F

Eosinophils do not have cytoplasm containing large purple/blue-staining granules. Instead, their granules are large but are orange/red in color. These granules are very distinctive for this type of cell, typically making their identification simple. ll of the following statements describe an eosinophil EXCEPT:

A. Cytoplasm contains large purple/blue-staining granules.

B. May be called an "eo"

C. Is a member of the granulocyte series

D. Cytoplasm contains large reddish-orange granules.

One of the key characteristics to the identification of Nocardia asteroides is its inability to hydrolyze casein, tyrosine or xanthine, as shown in this photograph. Nitrates are reduced to nitrites. Both Nocardia brasiliensis and Actinomadura madurae hydrolyze both casein and tyrosine; Streptomyces griseus hydrolyzes all three of the substrates.
Illustrated in this photograph is an agar quadrant plate containing casein (A), tyrosine (B), nitrate (C) and xanthine (D). None of the substrates have been hydrolyzed and nitrate has been reduced. The most likely identification is:

A. Nocardia asteroides

B. Nocardia brasiliensis

C. Streptomyces griseus

D. Actinomadura madurae

These are tyrosine crystals

Urinalysis & Other Body Fluids
True or false? Cystine crystals are present on this slide.

A. True

B. False

Hemoglobin H is a tetramer made of four beta globin chains. Hemoglobin H occurs when there is very limited alpha chain availability used to make normal hemoglobin A. Hemoglobin H forms in those affected with alpha thalassemia major as well as in people with the combination of two-gene deletion alpha thalassemia and hemoglobin Constant Spring.
Hematology
Which of the following combination of globin chains comprise Hemoglobin H?

A. 2 alpha, 2 beta

B. 2 alpha, 2 gamma

C. 4 beta chains

D. 4 alpha chains
