The ARDMS OB/GYN Sonography Specialty exam assesses clinical proficiency in diagnostic ultrasound for the female reproductive system and fetal development. Administered by ARDMS (Inteleos), this certification covers pelvic anatomy, first-trimester assessments, and complex second or third-trimester fetal evaluations. It confirms a sonographer's ability to perform accurate measurements and identify pathologies across various obstetric and gynecological conditions, ensuring standards of patient care and diagnostic accuracy in clinical ultrasound practice environments.
This exam is for sonographers performing or teaching OB/GYN ultrasound examinations. Candidates should have practical experience in clinical settings, including the ability to assess fetal anatomy, maternal pathology, and gynecological structures using standard ultrasound protocols and instrumentation.
Review the content outline to align your clinical knowledge with the five exam domains. Focus on the 37% weight assigned to second and third-trimester obstetrics. Practice identifying fetal anomalies, placental abnormalities, and measurement techniques. Use official ARDMS (Inteleos) resources to understand the 170-question format and ensure you are prepared for the 180-minute testing duration. Consistent practice with clinical scenarios will help you master the required diagnostic skills.
This domain covers the assessment of the female pelvis, including normal anatomy and physiological changes observed in the uterus, endometrium, and adnexa. Candidates must demonstrate proficiency in identifying normal structures and recognizing pathological variations during routine gynecological ultrasound examinations.
This section focuses on first-trimester obstetric examinations, including the identification of gestational structures and early pregnancy complications. Candidates are expected to evaluate embryonic development, confirm pregnancy viability, and identify potential abnormalities that may occur during the initial stages of gestation.
This domain addresses second and third-trimester fetal development, including detailed anatomical surveys and the identification of fetal and placental abnormalities. Mastery of this section is necessary, as it represents the largest portion of the examination content and requires precise diagnostic skills.
This area covers clinical standards, measurement techniques for gynecology and obstetrics, and the sonographer's role in specific medical procedures. Candidates must understand how to correlate clinical history with ultrasound findings and apply standardized protocols to ensure accurate and reproducible diagnostic results.
This domain involves the application of physics and instrumentation, including Doppler hemodynamics and imaging instrument settings. Candidates must demonstrate an understanding of how to optimize ultrasound equipment to achieve high-quality images while adhering to safety principles during all obstetric and gynecological procedures.
Arrive prepared for a 180-minute session containing 170 questions. Manage your time effectively across the five domains, noting that the second and third-trimester obstetric section carries the highest weight at 37%. Ensure you are familiar with all measurement protocols before beginning.
The ARDMS OB/GYN Sonography Specialty exam is designed to test your clinical knowledge through an assessment consisting of exactly 170 questions in total, which must be completed within the allotted time provided during your testing session.
To successfully achieve certification, candidates are required to meet the established performance standard, which is a passing score of 555 out of a possible 700 total points on the exam to demonstrate sufficient clinical competency.
Candidates are provided with a total duration of 180 minutes to complete the entire examination, which requires effective time management to ensure all questions are addressed within the testing period provided by the testing center.
