ASCP MLS EXAM QUESTIONS AND ANSWERS
What feature is most often found with patients with a splenectomy on a Wright’s
stained blood smear?
Howell-Jolly bodies
Patients with antibody to the following antigen are immune to Hepatitis B:
Surface antigen (HbSAg)
Which two of the following tests are helpful for documenting previous Streptococcal
throat and skin infections:
ASO titer and Anti-DNase B
In mass spectrometry, the “appearance potential” is defined as the:
Minimum energy required for the appearance of a particular fragment ion in mass
spectrum
What is generally accepted as the lower threshold value for semen pH from fertile
males?
7.2
Coulometry:
An automated method for measuring chloride which generates silver ions in the
reaction
Erythroleukemia:<\/p>\n\n\n\n

Also known as Acute Myelogenous Leukemia type M6. This type is associated with
either the presence of both erythroid and myeloid precursors OR strictly erythroid
precursors.
Myelomonocytic leukemia
Is associated with an increase in myeloid and monocytic cell precursors, but not red
blood cell precursors
Species that are Lysine (+), arginine (=) and ornithine (+):
Enterobacter aerogenes, Edwardsiella species and most Serratia species
Lysine reaction for all Citrobacter:
Negative
Key identifying characteristic for Pantoa (Enterobacter) agglomerans:
negative reactions for the three decarboxylases commonly tested ( Lysine, arginine
and ornithine)
Which organism is MOST likely responsible for septic reactions associated with Red
Blood Cell transfusions?
Yersina entercolitica is most likely responsible for septic reactions in transfusions of
Red Blood Cells. This organism is usually acquired by ingestion of contaminated food
and causes mild symptoms of abdominal pain and diarrhea. Growth of Y.
entercolitica is enhanced in iron-rich environments such as red cell components.
Gaucher’s disease<\/p>\n\n\n\n

The most common lysosomal storage disease caused by insufficient activity of the
lysosomal enzyme glucocerebrosidase that leads to the deposition of
glucocerebroside in cells of the macrophage-monocyte system.
Diseases associated with dysfunctions of polymorphonuclear neutrophils (PMNs)
Chediak-Higashi syndrome (CH), Chronic granulomatous disease (CGD),
Myeloperoxidase deficiency (MPO)
Nephrotic Syndrome:
Caused by damage to the kidneys, especially the basement membrane of the
glomerulus; which causes abnormal excretion of protein and red blood cells in the
urine. Fats are also present in the urine in most cases. A foamy appearance of the
urine is a key characteristic of this condition.
Clinical symptoms include:
Swelling
Weight gain from fluid retention
Poor appetite
High blood pressure
Key Biochemical reactions for Enterobacteriaceae:
The key biochemical reactions by which the family Enterobacteriaceae can be
identified include fermentation of carbohydrates, reduction of nitrates to nitrites
and the absence of cytochrome oxidase activity.
ANA
