MLT ASCP Board of Certification Exam – Study Guide &
Exam Prep | 2026 | Graded A+
1. Describe the significance of the APTT correction with increased incubation in the
context of coagulation factor deficiencies.
The APTT correction indicates that the patient has a vitamin K deficiency.
The APTT correction suggests a deficiency in the common pathway of
coagulation.
The APTT correction with increased incubation indicates that the deficiency is
likely due to a factor that is activated during the contact phase of coagulation,
such as prekallikrein.
The APTT correction is irrelevant to the diagnosis of coagulation disorders.
2. What type of leukemia is the patient most likely experiencing based on the lab
results?
Acute lymphocytic leukemia
Chronic lymphocytic leukemia
Acute myeloid leukemia
Chronic myeloid leukemia
3. What is the molecular weight of sulfosalicylic acid used in the calculation?
200
254
150
300
,4. Describe the significance of Factor VIII activity in the context of liver disease and
coagulation disorders.
Factor VIII activity is only useful for diagnosing hemophilia.
Factor VIII activity helps distinguish between severe liver disease and
disseminated intravascular coagulation, as it is typically decreased in liver disease
and may be normal or increased in DIC.
Factor VIII activity indicates the presence of vitamin deficiencies.
Factor VIII activity is irrelevant in diagnosing liver disease or DIC.
5. What is the term used to describe an elevated total granulocyte count above
9.0 x 10^3/uL?
Leukopenia
Granulocytopenia
Absolute neutrophilic leukocytosis
Neutrophilic hypoplasia
6. What is the screening test used to detect hemoglobin H?
Heat instability test
Coagulation profile
Serum osmolality
Urinalysis
7. Which of the following is an appropriate screening test for the presence of
hemoglobin S?
Heat instability test
, Dithionite solubility test
Acid elution test
Hemoglobin electrophoresis
8. Which species of Mycobacterium is known to typically fluoresce on a fluorochrome
stain?
M. tuberculosis
M. bovis
M. avium
M. leprae
9. Why are deglycerolized RBCs preferred for patients with high frequency antibodies
during transfusions?
Deglycerolized RBCs reduce the risk of hemolytic reactions caused by
antibodies against common antigens.
Deglycerolized RBCs enhance the immune response to infections.
Deglycerolized RBCs are less expensive than standard RBCs.
Deglycerolized RBCs are more compatible with all blood types.
10. Is autoreinfection possible in Strongyloide stercoralis infection? If yes, when?
No
Yes
11. What type of blood cell abnormalities are observed in patients with extensive
burns?
Platelets and reticulocytes
, Microspherocytes, schistocytes, and budding off of spherocytes
Eosinophils and basophils
Lymphocytes and monocytes
12. Describe the role of IgA in the body's immune response, particularly in secretions
like saliva and tears.
IgA plays a crucial role in mucosal immunity by protecting mucosal surfaces
from pathogens in secretions such as saliva and tears.
IgA is involved in the production of antibodies against bacterial infections in
the gut.
IgA is mainly found in the bloodstream and is responsible for systemic
immune responses.
IgA is primarily responsible for activating the complement system in the
bloodstream.
13. Describe the significance of normoblasts in a leukocyte count and how they affect
the interpretation of the results.
Normoblasts indicate a healthy bone marrow response and confirm the
leukocyte count.
Normoblasts are a type of leukocyte that increases the total count.
Normoblasts indicate a disturbance in hematopoiesis and can falsely
elevate the leukocyte count, necessitating adjustment for accurate
interpretation.
Normoblasts are irrelevant to leukocyte counts and do not affect the results.
14. Describe the relationship between warm autoimmune hemolytic anemia and the Rh
blood group system.
