Hereditary cancer risk assessment
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.21 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.
CDC screening guidelines for chlamydia and gonorrhea during pregnancy
All pregnant women aged <25 years, or older women at increased risk32 for infection, should be screened during their first prenatal visits.*
- Women found to have gonococcal infection should be treated immediately and retested within 3 months
- Those found to have chlamydial infection should have a test-of-cure (preferably by NAAT) 3 to 4 weeks after treatment and retested at 3 months
*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.

Obesity in pregnancy
More than half of pregnant women in the United States are overweight or obese,43 putting them at greater risk of pregnancy complications, such as gestational diabetes, preeclampsia, cesarean delivery, and giving birth to an infant with congenital anomalies. ACOG recommendations for counseling obese patients include:
- Discussing the increased risks to their baby
- Measuring their height and weight at their initial prenatal visit Guidelines that include a total weight gain of 15-25 lbs for overweight women (BMI=25-29.9) and 11-20 lbs for obese women (BMI≥30)
- Providing patients information on diet and exercise

Retesting for chlamydia and gonorrhea is important for those at increased risk
Those aged <25 years and those at increased risk* for chlamydia or gonococcal infection should be retested during their 3rd trimester.32
*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.
a 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 1 test, Hepatitis B Surface Antigen, is ordered to diagnose Hepatitis B in a pregnant person, additional tests such as liver enzymes should be ordered to confirm the diagnosis.
b Reflex testing may be performed at an additional charge.
c 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. Individual panel components can be ordered separately.
d The GDSP (Genetic Disease Screening Program) cfDNA Panel is a cell-free DNA test that can screen for increased risk of trisomy 21, trisomy 18 and trisomy 13, which are fetal chromosomal abnormalities that may cause birth defects. It can also screen for fetal sex, if elected. Supplemental cfDNA screening is also available for sex chromosome aneuploidies (SCAs) and/or microdeletions. The GDSP cfDNA Panel, as well as the supplemental tests for SCA and/or microdeletions, are “screening” tests, not a diagnostic tests, and therefore all positive (ie, increased risk) results should be followed by genetic counseling and further diagnostic testing and procedures, when clinically indicated. Pregnancy management decisions should not be based on the results of a cfDNA test alone. As with any test, there may be false positives or false negatives. The positive predictive value of the screening test varies by genetic marker, and may be lower for rare conditions. Performance data for the GDSP cfDNA Panel and for the supplemental screening tests may be obtained by contacting Quest Diagnostics at 1.866.GENE.INFO (1.866.436.3463).
e 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.
f If positive, test-of-cure should be performed within 3-4 weeks post-treatment.
Test codes may vary by location. Please contact your local laboratory for more information.
