Clinical Experience with UNITY Aneuploidy
Performance Characteristics of a Next Generation Sequencing-Based cfDNA Assay for Common Aneuploidies in a General Risk Population
Current clinical recommendations
- WEEK 10
- Gather paternal sample and analyze genotype. (assuming partner is available)
- WEEK 12
- Partner is negative for K and heterozygous for D (RhD) antigens. Amniocentesis is offered but declined due to risk of complications.
- WEEKS 12–36
- Blood drawn for antibody titer every 2-4 weeks.
- WEEK 37
- Deliver baby and check

Frequently Asked Questions
UNITY Complete takes advantage of a pregnancy's DNA (circulating cell-free DNA, ccfDNA) floating in the maternal bloodstream to assess for genetic changes. Some of these genetic changes are extremely small - like changes to single genes that can cause recessive conditions. Some of these genetic changes involve the presence of an entire extra chromosome (aneuploidies).
Our specialized QCT technology enables us to be able to count the genetic information we see from both mom and baby in a blood sample, and determine if there are differences that could indicate a baby has a higher chance of being affected with one of these conditions.
UNITY Complete offers comprehensive genetic screening from a single maternal blood sample - no partner sample required. The specific insights you receive depend on the tests you order based on your patient’s clinical needs.
UNITY Aneuploidy™ Screen checks for chromosomal conditions caused by extra or missing chromosomes, including Trisomy 21, Trisomy 18, Trisomy 13, Monosomy X, XXX, XXY, and XYY. This test also provides fetal sex determination and, for twin pregnancies, identifies whether the twins are identical or fraternal.
Depending on your patient's clinical history, you may also order:
• UNITY Fetal RhD NIPT for patients with RhD-negative blood type.
• UNITY Fetal Antigen NIPT for patients who are alloimmunized to certain antigens.
• 22q11.2 microdeletion analysis
UNITY Fetal Risk™ Screen offers two panels to assess carrier status for up to 14 recessive and x-linked conditions:
• ACOG Guideline Panel (5 conditions): Screens for conditions recommended by the American College of Obstetricians and Gynecologists (ACOG), such as cystic fibrosis, spinal muscular atrophy, sickle cell disease, alpha-thalassemia, and beta-thalassemia.
• ACOG Guideline PLUS Panel (14 conditions): Includes all conditions from the ACOG Guideline Panel, plus additional conditions prevalent in Ashkenazi Jewish and pan-ethnic populations such as Tay Sachs Disease, DMD-Associated Dystrophinopathies, Phenylalanine Hydroxylase Deficiency (PKU), and others.
If a patient is found to be a carrier for any of these conditions, fetal testing will automatically be performed using cell-free DNA to assess the likelihood of the fetus being affected. The fetal risk result will indicate whether the risk is low or high for each condition. Please note that fetal risk assessment may not be available for certain cases, such as twin pregnancies or those involving egg donation.
Additionally, you may choose to order carrier screening for Fragile X syndrome. If the patient is a carrier, our assay can perform cell-free DNA analysis to determine the fetus's sex, as male fetuses are at a higher risk of developing Fragile X syndrome.

UNITY Aneuploidy Screen results are typically reported as either low-risk or high-risk.
Low-Risk Fetus: This indicates a very low chance that the pregnancy is affected by the conditions tested, though it does not completely eliminate the possibility.
High-Risk Fetus: This indicates an increased likelihood that the pregnancy may be affected by a specific condition. In the case of a high-risk result, follow-up testing such as chorionic villus sampling (CVS), amniocentesis, or post-birth evaluations is generally recommended.
Important: A high-risk result does not guarantee an unhealthy pregnancy and does not rule out other genetic conditions or birth defects.
UNITY Fetal Risk Screen evaluates maternal carrier status for various conditions. If the patient is identified as a carrier, fetal risk assessment will be automatically performed using cell-free DNA. The results will provide either a low-risk or high-risk determination for each condition tested.
