Double Marker Test Explained: Early Screening for Chromosomal Abnormalities

-

double marker test price near me
When a developing foetus has an extra or missing chromosome, it can cause medical problems. The most common chromosomal abnormalities include Down syndrome (or trisomy 21) which occurs when there is an extra copy of chromosome 21. This causes mental retardation, typical facial features, and, sometimes, birth defects. In Trisomy 13 and trisomy 18, there is an extra copy of chromosome 13 or chromosome 18. In such a case, pregnancy often ends in miscarriage. 

To detect chromosomal abnormalities, a screening test is done in the 11th and 13th weeks of pregnancy. It is called a double marker test. This test evaluates the levels of:

1. Free Beta hCG (Human Chorionic Gonadotropin): This hormone is produced by the placenta during pregnancy. Elevated levels may indicate chromosomal risks.

2. PAPP-A (Pregnancy-Associated Plasma Protein-A): This protein is produced by the placenta to maintain its health. Low levels may indicate placental issues or chromosomal disorders.

The test offers several benefits as it plays a vital role in the early pregnancy care for several reasons: 

Non-Invasive: Since it is a normal blood test, it does not pose any risk to the baby or mother.

Early Detection: With the early identification of genetic abnormalities, the doctor can suggest additional diagnostic tests, such as amniocentesis or CVS, for a more conclusive diagnosis.

Reassurance: Getting insights into the baby’s genetic health  helps reduce parental anxiety.

Ultrasound, also known as sonography, is a non-invasive imaging test that is widely used for diagnostic purposes. Ultrasound uses high-frequency sound waves to create real-time images of internal organs and soft tissues, such as blood vessels. The images are created by a computer that captures and processes the echoes returning from the body. Unlike x-rays and MRIs, ultrasound does not use radiation, making it completely safe and a commonly used diagnosis procedure. Why do you need an ultrasound scan? Your doctor may recommend ultrasound to have an overview of the body area they will be checking. There are many reasons why you may need to take up ultrasound scan. The two major types of ultrasounds recommended include: Pregnancy ultrasound Doctors may recommend it for reasons such as: Confirm the pregnancy Assess the baby’s size and position Find out if you are pregnant with more than one baby Estimate gestational age or duration of the pregnancy Screen for Down syndrome Evaluate birth ...

PET-CT Scanning: Revolutionising Cancer Detection and Treatment Monitoring

-
Image
Positron emission tomography (PET) is one of the most promising medical imaging technologies currently available in the medical world. It uses a small amount of radioactive tracers or radiopharmaceuticals to visualise molecular processes in the body. By measuring changes at the cellular level, the modality may help evaluate the disease before other imaging tests. It is an accurate imaging method that helps in the diagnosis, staging, restaging, and therapeutic monitoring of many common cancers. What is PET/CT scanning? PET imaging or a PET scan is a type of nuclear medicine imaging. It combines computed tomography (CT) and PET in one single imaging method and presents results that help doctors in making treatment decisions. While the PET image reveals the functioning of the body, the CT image tells about the anatomic structure. If you live in Delhi-NCR, you can do an online search to know PET CT scan price . How does a PET-CT work? For this test, a PET radiotracer 18F-fluorodeoxyglucose...

A magnetic resonance imaging (MRI) scan is a non-invasive imaging method that uses powerful magnets, radio waves and a computer to create detailed images of the inside of the body. These scanners are often used to examine various body parts, such as joints, breasts, heart, blood vessels, brain, spinal cord, bones, and internal organs, to detect anomalies and other conditions. How MRIs work MRI scanners use powerful magnets to align water protons in the body with the magnetic field during the scan. During the realignment, protons emit radio signals that get translated into detailed images by a computer. These images provide crucial insights into the body area being examined. Contrast vs. non-contrast MRI: To create better images, sometimes the doctor may order a contrast scan. For this, a contrast dye, typically gadolinium, is injected before an MRI to enhance the visibility of internal structures or detect subtle tissue variations. The injectable dye helps highlight areas of inflammati...
