3. Non-Invasive Prenatal Testing (NIPT): A more advanced blood test that analyzes fetal DNA circulating in the mother’s blood, providing a higher accuracy rate for detecting certain chromosomal conditions.

Signs and Symptoms

Asymptomatic Nature

It is important to note that antenatal screening for chromosomal anomalies is typically performed on asymptomatic individuals. Most patients do not exhibit any signs or symptoms of chromosomal anomalies during the screening process. The purpose of the screening is preventive, aimed at identifying risks rather than diagnosing existing conditions.

Follow-Up for Positive Results

If screening tests indicate a higher risk for chromosomal anomalies, further diagnostic testing may be recommended, such as:
- Chorionic Villus Sampling (CVS): Usually performed between 10 and 13 weeks of gestation.
- Amniocentesis: Typically conducted between 15 and 20 weeks of gestation.

These procedures can provide definitive information about chromosomal conditions but carry risks, including miscarriage.

Patient Characteristics

Demographics

Patients undergoing antenatal screening for chromosomal anomalies often include:
- Age: Women over the age of 35 are generally considered at higher risk for chromosomal abnormalities and are more likely to be offered screening.
- Family History: Individuals with a family history of genetic disorders may also be encouraged to participate in screening.
- Previous Pregnancy Outcomes: Women who have had previous pregnancies with chromosomal anomalies may be more likely to seek screening.

Socioeconomic Factors

Access to antenatal screening can also be influenced by socioeconomic status, education level, and healthcare access.
