ACOG recommends that OB/GYNs perform a hereditary cancer risk assessment to help identify patients who may be at risk of developing certain types of cancer.1 For patients with a family or personal history of breast or ovarian cancer, Ashkenazi Jewish ancestry, or other potential heritable conditions, genetic testing can provide valuable information to help inform the best treatment decisions. Our hereditary cancer testing is performed on a next-generation sequencing platform in conjunction with our proprietary software to allow for the most accurate identification of disease.
All pregnant women aged <25 years, or older women at increased risk2 for infection, should be screened during their first prenatal visits.*
*Patients with increased risk are women with a history of multiple sexual partners or a sexual partner with multiple contacts, sexual contact with individuals with culture-proven STDs, a history of repeated episodes of STDs, or attendance at clinics for STDs.
QNatal® Advanced is a low-risk, noninvasive cell-free DNA (cfDNA) prenatal screen that can detect the most common fetal aneuploidies, including Down syndrome.

Those aged <25 years and those at increased risk* for chlamydia or gonococcal infection should be retested during their 3rd trimester.2
*Patients are women with a history of multiple sexual partners or a sexual partner with multiple contacts, sexual contact with individuals with culture-proven STDs, a history of repeated episodes of STDs, or attendance at clinics for STDs.
a The age-based offerings are based on ACOG recommendations and include image-guided Pap tests. Non-imaged Paps as well as conventional Paps are also available at Quest Diagnostics. Test codes may vary by location. Please contact your local laboratory or go to QuestDiagnostics.com/TestCenter for more information.
b Reflex testing may be performed at an additional charge.
c Risk factors include known HIV infection; close contact with individuals known or suspected to have TB; medical risk factors such as diabetes, lupus, cancer, alcoholism, and drug addiction; birth in or emigration from countries with high prevalence; being medically underserved; homelessness; living or working in long-term care facilities, such as correctional institutions, mental health institutions, and nursing homes.
d If positive, test-of-cure should be performed within 3-4 weeks post-treatment.
e If Antibody Screen is positive, Antibody Identification, Titer, and Antigen Typing will be performed at an additional charge. If RPR screen is reactive, RPR Titer and FTA Confirmatory testing will be performed at an additional charge. When only a single test, Hepatitis B Surface Antigen, is ordered to diagnose Hepatitis B in a pregnant woman, additional tests such as liver enzymes should be ordered to confirm the diagnosis.
Test codes may vary by location. Please contact your local laboratory for more information.
