Master Bethesda 2014 cervical reporting, organisms (Trichomonas, Candida, HSV, HPV/koilocytes), CLIA workload (100 slides/24h cap, 10% rescreen, 5-yr retrospective), and ASCCP 2019 risk-based management.

Sample CTgyn Practice Questions

Try these sample questions to test your CTgyn exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1In the Bethesda 2014 system, what is the minimum squamous cellularity required for a satisfactory liquid-based Pap specimen?
A.2,000 well-visualized squamous cells
B.5,000 well-visualized squamous cells
C.8,000 well-visualized squamous cells
D.12,000 well-visualized squamous cells
Explanation: Bethesda 2014 requires an estimated minimum of 5,000 well-visualized/well-preserved squamous cells for liquid-based preparations to be considered adequate for evaluation. Cellularity is typically estimated by counting representative fields and extrapolating.
2What is the minimum squamous cellularity for a satisfactory conventional Pap smear under Bethesda 2014?
A.2,000–5,000 cells
B.5,000–8,000 cells
C.8,000–12,000 cells
D.15,000–20,000 cells
Explanation: Conventional smears require an estimated 8,000 to 12,000 well-preserved/well-visualized squamous cells distributed across the slide for adequacy under Bethesda 2014.
3Under Bethesda 2014, what constitutes adequate transformation zone (TZ) sampling?
A.At least 5 endocervical or squamous metaplastic cells in clusters/singles
B.At least 10 endocervical or squamous metaplastic cells in clusters/singles
C.At least 50 endocervical or squamous metaplastic cells
D.Endocervical cells only — metaplastic cells do not count
Explanation: Bethesda 2014 defines adequate TZ sampling as at least 10 well-preserved endocervical or squamous metaplastic cells, in clusters or as singles. Lack of TZ component is reported as a quality indicator but does not by itself render the specimen unsatisfactory.
4A Pap is reported as 'Negative for Intraepithelial Lesion or Malignancy (NILM).' What does this category include?
A.Only purely normal squamous and glandular cells
B.Normal cells AND organisms/reactive changes without epithelial abnormality
C.Only ASC-US cases ruled out as reactive
D.Specimens lacking endocervical cells
Explanation: NILM encompasses normal cellular findings as well as benign organism-related changes (Trichomonas, Candida, BV shift, Actinomyces, HSV) and reactive cellular changes (inflammation, repair, IUD, radiation, atrophy) — provided no epithelial abnormality is identified.
5Which Bethesda category indicates squamous atypia that cannot exclude a high-grade lesion?
A.ASC-US
B.ASC-H
C.LSIL
D.AGC-NOS
Explanation: ASC-H (Atypical Squamous Cells, cannot exclude High-grade SIL) describes squamous cells with features suggestive of HSIL but quantitatively or qualitatively insufficient for definitive diagnosis. It carries a much higher risk of underlying CIN2+ than ASC-US.
6Which finding belongs in the LSIL category under Bethesda 2014?
A.CIN 2 (moderate dysplasia)
B.CIN 3 (severe dysplasia/CIS)
C.HPV cytopathic effect (koilocytosis) and/or CIN 1
D.Adenocarcinoma in situ
Explanation: LSIL groups HPV cytopathic effect (koilocytosis) with mild dysplasia/CIN 1, reflecting their similar biology and management. CIN 2 and CIN 3 are categorized as HSIL.
7Which lesions are grouped under HSIL in the Bethesda system?
A.CIN 1 only
B.CIN 1 and CIN 2
C.CIN 2, CIN 3, and CIS
D.Only invasive squamous carcinoma
Explanation: HSIL encompasses CIN 2 (moderate dysplasia), CIN 3 (severe dysplasia), and carcinoma in situ — lesions sharing high-risk HPV biology and elevated cancer progression risk.
8Which subcategory of AGC indicates the highest immediate risk of malignancy and requires the most aggressive workup?
A.AGC, NOS
B.AGC, favor neoplastic
C.Endocervical adenocarcinoma in situ (AIS)
D.ASC-US
Explanation: AIS is a definitive precursor of invasive endocervical adenocarcinoma. Among glandular Bethesda categories, AIS carries the highest established risk of underlying neoplasia after invasive carcinoma itself.
9In what age group are benign-appearing endometrial cells specifically reported under Bethesda 2014?
A.≥30 years
B.≥40 years
C.≥45 years
D.≥55 years
Explanation: Bethesda 2014 lowered the threshold to age ≥45 years for reporting benign-appearing endometrial cells, since their presence may indicate endometrial pathology in this age group, particularly in postmenopausal women.
10A specimen with obscuring blood covering >75% of cells should be reported as:
A.NILM
B.Satisfactory but limited
C.Unsatisfactory for evaluation
D.ASC-US
Explanation: Per Bethesda 2014, when more than 75% of epithelial cells are obscured by blood, inflammation, or other interfering substances, the specimen is reported as Unsatisfactory for evaluation, with the reason specified.

About the CTgyn Exam

ASCP BOC technician-level credential for gynecologic cytology screeners. Validates expertise specific to cervical Pap screening: Bethesda 2014 system (NILM, ASC-US, ASC-H, LSIL, HSIL, AGC, AIS), normal cytology and reactive changes, infections (Trichomonas, Candida, HSV, HPV), precursor and malignant lesions, Pap stain and liquid-based prep methods, and CLIA-mandated cytology screening workload limits. NOTE: CTgyn(ASCPi) is a separate international variant — only US CTgyn(ASCP) qualifies for CLIA-mandated screening in US labs.

CTgyn Study Tips from Top Performers

1Master Bethesda 2014 categories with morphologic features for each
2Memorize organisms by morphology: Trichomonas (pear-shaped flagellate), Candida (pseudohyphae + yeast), HSV (multinucleation/molding/margination, ground-glass nuclei), HPV (koilocytes — perinuclear halo + nuclear atypia), Actinomyces (sulfur granules)
3Know CLIA workload: 100 slides/24h max (recalculated by case mix), 10% rescreen, 5-yr retrospective for HSIL+
4Apply ASCCP 2019 risk-based management thresholds: ≥4% 5-yr CIN3+ risk = colposcopy; ≥60% = expedited treatment
5Understand Pap stain: hematoxylin (nuclear) + EA-50/EA-65 (cytoplasmic eosin azure) + Orange G (keratinization)

Frequently Asked Questions

What's the difference between CTgyn(ASCP) and CTgyn(ASCPi)?

CTgyn(ASCP) is the US credential for gynecologic cytologists — qualifying for CLIA-regulated cervical screening in US labs. CTgyn(ASCPi) is the international (ASCP International) variant, designed for non-US contexts. Holders of CTgyn(ASCPi) ALONE do NOT qualify for CLIA-mandated screening in US labs; they need to obtain US CTgyn(ASCP) for US practice.

What is Bethesda 2014?

The 3rd edition Bethesda System for Reporting Cervical Cytology (2014). Categories: NILM (Negative for Intraepithelial Lesion or Malignancy), ASC-US (atypical squamous cells of undetermined significance), ASC-H (cannot exclude HSIL), LSIL (HPV/CIN1), HSIL (CIN2/CIN3), AGC (atypical glandular cells with subtypes), AIS (adenocarcinoma in situ), squamous cell carcinoma, adenocarcinoma. Adequacy criteria: ≥5,000 squamous cells liquid-based or ≥8,000-12,000 conventional; transformation zone component (10 endocervical/squamous metaplastic cells).

What are the CLIA workload limits?

Per CLIA: cytotech max 100 slides screened in any 24-hour period (recalculated based on case mix — abnormals count more, negatives count 1); cannot screen >8 hours in 24h; 10% of negative cases require rescreen for QC; 5-year retrospective rescreen of prior negatives required when index HSIL+ found. CLIA rules apply equally to gynecologic cytologists and full cytotechnologists.

How should I study for ASCP CTgyn?

Plan 40-60 hours over 6-8 weeks. Focus on Bethesda 2014 (25%), normal/reactive cytology (25%), and organisms/infections (25%) — together 75% of exam. Master morphologic features (HSV 3 M's = multinucleation, molding, margination; HPV koilocytes; Trichomonas pear-shaped flagellate), CLIA workload caps, and ASCCP 2019 Risk-Based Management.
