CT(ASCP) Cytotechnologist Certification Exam 2026:
Comprehensive Board Practice Test — Gynaecologic Cytology,
Respiratory & Genitourinary Cytology, Body Cavity Fluids, Fine
Needle Aspiration & Laboratory Operations — 190 Multiple-Choice
Questions with Answers & Detailed Rationales
SECTION I: GYNECOLOGICAL CYTOLOGY (Questions 1-80)
Question 1
A 28-year-old woman presents for routine cervical screening. The cytology specimen shows
superficial squamous cells with small, pyknotic nuclei and abundant transparent cytoplasm.
What is the most likely hormonal status?
A. Atrophic
B. Proliferative
C. Ovulatory
D. Luteal
Correct Answer: C
Explanation: Ovulatory smears feature superficial cells with pyknotic nuclei, clean
background, and minimal inflammation. Best practice: correlate hormonal pattern with
clinical history.
Question 2
A postmenopausal woman presents with vaginal bleeding. Cytology reveals endometrial
cells in a Pap test. According to Bethesda System guidelines, how should this finding be
reported?
A. Normal for age
,B. Endometrial cells in a woman ≥45 years
C. Benign cellular changes
D. Unsatisfactory for evaluation
Correct Answer: B
Explanation: In women ≥45, endometrial cells on Pap require reporting regardless of
bleeding status. Clinical pearl: postmenopausal bleeding mandates endometrial sampling.
Question 3
A 35-year-old woman's Pap shows squamous cells with enlarged, hyperchromatic nuclei and
irregular nuclear membranes occupying most of the cell. What Bethesda category is most
appropriate?
A. ASC-US
B. LSIL
C. HSIL
D. AGC
Correct Answer: C
Explanation: High-grade squamous intraepithelial lesion features high N:C ratio,
hyperchromasia, and membrane irregularity. Best practice: HSIL requires immediate
colposcopy.
Question 4
A liquid-based Pap from a 42-year-old shows abundant orangeophilic squamous cells with
pyknotic nuclei and no visible cytoplasm. What is the most likely cause?
A. HPV cytopathic effect
,B. Air-drying artifact
C. Atrophic vaginitis
D. Keratinizing dysplasia
Correct Answer: B
Explanation: Orangeophilic pseudoparakeratotic cells with pyknotic nuclei result from air-
drying. Fix immediately after smear preparation to prevent artifact.
Question 5
A 52-year-old woman's Pap shows small, round cells with scanty cytoplasm forming loose
aggregates with nuclear molding. What is the differential diagnosis?
A. LSIL
B. Endometrial cells
C. Small cell carcinoma
D. Reserve cell hyperplasia
Correct Answer: C
Explanation: Nuclear molding, scant cytoplasm, and loose aggregates suggest small cell
carcinoma. Clinical pearl: confirm with immunocytochemistry for neuroendocrine markers.
Question 6
A 30-year-old woman with HIV has a Pap showing large cells with multilobated nuclei and
prominent intranuclear inclusions. What organism is most likely?
A. Herpes simplex virus
B. Cytomegalovirus
, C. Human papillomavirus
D. Chlamydia trachomatis
Correct Answer: B
Explanation: CMV produces cytomegaly with intranuclear and intracytoplasmic inclusions.
Immunocompromised status increases risk; best practice: correlate with serology.
Question 7
A Pap from a 45-year-old shows sheets of glandular cells with nuclear crowding,
stratification, and rosette formation. What is the most appropriate Bethesda interpretation?
A. AGC favor neoplastic
B. AGC not otherwise specified
C. Adenocarcinoma
D. Normal endocervical cells
Correct Answer: A
Explanation: Rosette formation, nuclear crowding, and stratification favor neoplastic
glandular changes. Clinical pearl: AGC favor neoplastic warrants colposcopy with
endocervical sampling.
Question 8
A 29-year-old woman's Pap shows parabasal cells with enlarged nuclei and perinuclear
halos. What is the most likely diagnosis?
A. LSIL
B. Atrophic vaginitis
