ASCP MLS Exam Questions and
Answers 100% Solved | Rated A+
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: - ✔✔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 - ✔✔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
