Biophysical Profile - After 28 weeks as required

A Biophysical Profile (BPP) is an advanced test that is performed after 28 weeks of pregnancy to evaluate the overall well-being of your baby. It combines an ultrasound scan with a non-stress test (NST) to monitor both physical activity and oxygen supply.

This scan aims to establish:

  • Fetal Breathing Movements: Checks if the baby is practicing breathing inside the womb.
  • Fetal Body Movements & Muscle Tone: Observes the baby’s movements, stretching, and activity levels.
  • Amniotic Fluid Volume: Measures fluid levels, ensuring the baby has a safe environment for growth.
  • Heart Rate Monitoring: Evaluates the heart rate of the baby and checks the response to movements.
  • Overall Well-being: Detects signs of fetal distress and helps doctors decide if early delivery may be required.

Other available pregnancy scans

These specialised tests are recommended only when medically indicated or in high-risk pregnancies. They support advanced prenatal diagnosis and guide clinical decision-making.

Early Level II Scan (Around 16 Weeks)

Recommended when early screening suggests increased risk. This scan provides an early, detailed structural evaluation of the fetus.

View Test Details

Early Level II Scan (Around 16 Weeks)

The Early Level II Scan is a specialised fetal ultrasound performed around 16 weeks of pregnancy, primarily recommended for pregnancies identified as high risk during early screening. This scan allows doctors to evaluate the baby’s anatomy earlier than the routine anomaly scan and helps in identifying major structural abnormalities at an early stage.

When is an Early Level II Scan Recommended?

This scan is usually advised when:

  • NT scan or dual marker results indicate increased risk
  • There is a family history of genetic or congenital conditions
  • The mother has medical conditions affecting pregnancy
  • There is a history of pregnancy complications
  • Advanced maternal age is a factor
What Does the Scan Evaluate?
  • Brain and spinal development
  • Heart structure and major vessels
  • Limbs and skeletal formation
  • Abdominal organs
  • Facial structures
  • Amniotic fluid and placenta
Why is This Scan Important?

Detecting abnormalities at an early stage allows:

  • Better pregnancy monitoring
  • Timely referral to specialists
  • Informed medical decisions
  • Psychological preparedness for parents
How is the Scan Performed at ANH?

Chorionic Villus Sampling (CVS) Test

A diagnostic test used for the early detection of genetic and chromosomal conditions in selected pregnancies.

Explore CVS Test

Chorionic Villus Sampling (CVS) is an invasive prenatal diagnostic test performed between 12 and 14 weeks of pregnancy to detect specific genetic and chromosomal abnormalities. This test is recommended only in selected or high-risk pregnancies when early confirmation of fetal genetic health is required.

When is CVS Recommended?

CVS may be advised when:

  • An NT scan or dual marker test indicates increased genetic risk
  • There is a known family history of genetic disorders
  • The previous pregnancy had chromosomal abnormalities
  • The mother is of advanced maternal age
  • Non-invasive screening suggests possible abnormalities
What Does CVS Detect?
  • Chromosomal abnormalities such as Down syndrome
  • Genetic disorders inherited from parents
  • Certain rare metabolic or inherited conditions

Unlike screening tests, CVS provides a definitive diagnosis, not just risk assessment.

How is CVS Performed?

The procedure involves collecting a small sample of placental tissue (chorionic villi) under continuous ultrasound guidance.

At ANH, CVS is performed with:

  • Advanced ultrasound imaging
  • Expert fetal medicine specialists
  • Strict safety and sterility protocols
  • Careful post-procedure monitoring
Is CVS Safe?

CVS is generally safe when performed by experienced specialists. However, being an invasive test, it carries a small risk, which is thoroughly discussed with parents before proceeding.

CVS vs Other Prenatal Tests
  • Provides early diagnosis between 12–14 weeks
  • Unlike NIPT or marker tests, CVS confirms genetic conditions
  • Recommended only when medically indicated

Learn About Amniocentesis

Amniocentesis is an invasive prenatal diagnostic test usually performed around 16 weeks of pregnancy to confirm genetic and chromosomal conditions when screening tests indicate an increased risk. It is a confirmatory test and is recommended only when medically necessary.

When is Amniocentesis Recommended?

Amniocentesis may be advised when:

  • An NT scan or a Level 2 ultrasound scan shows abnormalities
  • Dual or triple marker tests indicate high genetic risk
  • NIPT suggests possible chromosomal disorders

  • The mother is of advanced maternal age
What Does Amniocentesis Detect?
  • Chromosomal abnormalities such as Down syndrome
  • Neural tube defects
  • Certain inherited genetic disorders
  • Fetal infections in selected cases
How is Amniocentesis Performed?

The procedure involves withdrawing a small amount of amniotic fluid using a fine needle under continuous ultrasound guidance.

At ANH, the test is performed using:

  • High-resolution ultrasound systems
  • AI-assisted imaging support
  • Experienced fetal medicine specialists
  • Strict infection control and safety protocols
Is Amniocentesis Safe?

Amniocentesis is generally safe when performed by trained specialists. However, as it is invasive, it carries a small risk, which is carefully explained and discussed with parents before proceeding.

Amniocentesis vs Other Prenatal Tests
  • Provides a confirmed diagnosis
  • Unlike NIPT or marker tests, it does not estimate risk—it confirms conditions
  • Recommended only when clinically indicated
