Understanding Quad Marker test With Graph in Amritsar
What is Quad Marker test With Graph in Amritsar?
Quad Marker test with graph is a blood test that measures the levels of four important substances in the placenta namely alpha-fetoprotein, human chorionic gonadotropin, estriol, and inhibin A. It helps diagnose genetic disorders and neural tube defects along with ectopic pregnancy and miscarriages. This test is done between 15 and 21 weeks of pregnancy.
The quad marker is used as a screening test only and any abnormal result does not mean that the fetus has a birth defect or genetic condition.
Females above 35 years of age and who have a family history of birth defects have a higher risk of getting abnormal values of these markers. They are typically offered further testing, this includes repeating the quad marker with a high-definition ultrasound.

Frequently Asked Questions about Quad Marker test With Graph in Amritsar
Q. Is there any preparation required before the test?
Inform the doctor about the medications you may be taking. No other specific preparations are usually required before this test.
Q. Can the defects in fetus be caused because of the age of pregnant women?
Yes, a pregnant woman who is 35 years or older has a greater risk of developing defects in the fetus. Apart from that, other factors such as exposure of the woman to high levels of radiation, diabetes or if the woman is taking insulin can affect the development of the fetus. Viral infection at the time of pregnancy can also be a risk factor in the development of the fetus.
Q. What other tests are required for diagnosis of abnormalities in fetus?
In case the results are abnormal, the doctor may advise amniocentesis in which a thin, hollow needle is used to withdraw amniotic fluid (the fluid that surrounds the fetus) from the uterus. This test is useful to detect any genetic or fetal conditions present in the fetus.
If the levels of AFP are high, the doctor will advise ultrasound for a detailed examination of neural tube defects.
Q. Is Quad marker with graph test only advised for women of age 35 years or more?
No, this test is not specific for women of age 35 years or more. Every pregnant woman is advised to take this test, as it is very important for detecting any abnormality in the fetus before birth. This test is done between 14 and 22 weeks of pregnancy. However, the best time for this test is between 15 and 20 weeks of pregnancy.
Q. How is the blood sample taken?
The healthcare provider takes a blood sample from the arm. The site from where the blood is to be withdrawn is cleaned with a swab of rubbing alcohol. This is then followed by inserting a small needle which has a tube attached to it for collecting blood. Once the sufficient blood for analysis is withdrawn, the needle is removed. The site is then covered with a gauze pad.
Q. Is there any risk associated with the withdrawal of blood sample procedure?
As such there is no risk but in few cases, bruising, bleeding, and infection at the puncture site can be seen. In very few cases, there can be swelling of the vein after the blood is withdrawn.
Q. What is Down's syndrome?
It is a genetic disorder in which extra genetic material from chromosome 21 gets transferred to the fetus. This transfer affects the development of the fetus leading to abnormal development both physically and mentally. The affected baby will have a small head and short neck, obliquely positioned eyes looking in an upward direction, large tongue coming out of the mouth, flat face, wide hands with short fingers, and lack of muscle tone.
Q. What is Trisomy 18?
It is also known as Edwards Syndrome which is caused by the development of an extra chromosome 18. Because of this, the normal pattern of development in the baby gets disturbed even before its birth. The effects caused by Trisomy 18 are very complicated as compared to Down syndrome. The effects are so severe that it can cause stillbirth (death at the time of birth) of the child.
