ASCP EXAMS WITH CORRECT
ANSWERS 2025-2026
1. Which of the following instruments measures changes in vapor
pressure? - ANSWER-Osmometer
2. What abnormal red blood cell inclusion is composed of multiple small,
dark blue aggregates of ribosomes (RNA) that are distributed
throughout the RBC? - ANSWER-Basophilic stippling
3. A situation may arise when a pathologist recognizes the presence of a
parasite in an H & E - stained section within the lumen of the appendix,
as seen in the upper Image. Studies of additional fields of view in the
slide may locate the ovary and reveal the morphology of the ova
contained within, as is observed in the lower image. Based on these
observations, select the presumptive identification of this parasite. -
ANSWER-Enterobius vermicularis
4. Components of the second line of defense in the human body are -
ANSWER-Phagocytic cells; complement
5. Which of the following is true regarding the Lutheran blood group
system? - ANSWER-Lu^b is a high frequency antigen
6. Which of the following is a cause of metabolic alkalosis? - ANSWER-
Excessive vomiting
7. Parasites which can be found in urinary sediment include all of the
following EXCEPT: - ANSWER-Plasmodium malariae
,8. The production of neutral 17-ketosteroids is a measure of which of the
following? - ANSWER-Androgen production
9. Which component of an electrophoresis system sets the pH? -
ANSWER-Buffer
10. Which of the following casts might be found in the urine of a
healthy individual after strenuous exercise? - ANSWER-Hyaline casts
and granular casts
11. What are the abnormal red blood cells (RBCs) indicated by the
arrows that may be suggestive of an individual possessing the Rh null
phenotype? - ANSWER-Stomatocytes
12. Which of the following antibody types is the predominant serum
antibody seen in the secondary immune response - ANSWER-IgG
13. Which of the following antibodies is the MOST common cause of
severe hemolytic disease of the newborn? - ANSWER-Anti-D
14. Small intracellular gram-negative cocci were observed in a
centrifuged spinal fluid sediment as presented in the upper
photomicrograph. A clinical diagnosis of meningitis was suspected.
Yellow-gray colonies after 24-hour incubation had been observed on
blood agar. Based on the carbohydrate utilization tube reactions
observed in the lower photograph, what is the presumptive
identification of this isolate. - ANSWER-Neisseria meningitidis
15. Which of the following conditions is MOST frequently associated
with anti-I? - ANSWER-Cold agglutinin disease
, 16. The site most frequently used to collect bone marrow samples
from adults is: - ANSWER-Posterior iliac crest
17. A 56-year-old woman with a history of high blood pressure and
cardiovascular disease is evaluated by her physician due to her recent
loss of appetite. The doctor reviews the following test results:
18. Plasma creatinine = 2.4 mg/dL
19. Urine creatinine = 65 mg/dL
20. Urine volume (24 hrs) = 1400 mL
21. What is the estimated glomerular filtration rate for this patient? -
ANSWER-(Urine creatinine / plasma creatinine) x (volume / minute) =
glomerular filtration rate (mL/min)
22. *in order to solve this problem, the 24 hour urine must be
converted into minutes. 1440 minutes should be used as the
denominator in the volume component.
23. So...for this patient, the calculation would be:
24. ( 65 mg/dL / 2.4 mg/dL ) X ( 1400 mL / 1440 min ) = (27.083) X
(0.972 mL/min) =
25. = 26.32 mL/min
26. All of the listed disorders are organ non-specific autoimmune
diseases EXCEPT: - ANSWER-Hashimoto's disease
27. What is the main function of thrombocytes? - ANSWER-To assist
in the coagulation process
28. A lipid panel consists of which of the following tests? - ANSWER-
Cholesterol, Lipoprotein, HDL, Triglycerides
29. Which Aspergillus species show biseriate with phialides covering
the entire surface of a spherical vesicle with black conidia as
microscopic morphological features? - ANSWER-Aspergillus niger
