How this test is performed

A double marker test is performed by taking blood samples to look for HCG AND PAPP -A (
HCG =human chorionic gonadotropin)
( PAPP-A = Pregnancy-associated plasma protein A)and with ultrasound. The blood samples
help doctors to determine neurological or Chromosome defects with the baby.

HCG is tested because it produces placenta during pregnancy. The level of the placenta
indicates trisomy 18 and down syndrome.
A low level of PAPP-A indicates a high risk of down syndrome.
What a normal report of HCG AND PAPP-A
HCG level should be 25700 to 28800 Miu/ml for all age women
PAPP- A normal level will be- 1 MOM (multiple of median) for all age women.

What is Down syndrome?

In the medical field, Down syndrome is known as trisomy genetic disorder. Each cell is made
up of 46 chromosomes, of which 23 are chromosomes. To form an embryo two cells with 23
chromosomes each must combine (sperm and egg) to form a 46-pair zygote, which
eventually develops into an embryo.

In some cases, during cell division, an extra chromosome is transferred between two chromosomes. So instead of two, there are three chromosomes. In Down syndrome, 21 pairs have three chromosomes instead of two. This
anomaly is seen as the most common physical and cognitive features seen with Down syndrome.

Two-dimensional markers help determine this condition by examining mutant markers if the
embryo with this extra chromosome is present. These marks can also be used to diagnose
other diseases, namely, Edward syndrome (chromosome trisomy 18) and Patau syndrome
(chromosome trisomy 13). Since this is very rare compared to Down syndrome, it is rarely

Several tests are performed during pregnancy to monitor the health of the mother and
baby. Basically, a marking test is performed to check for birth defects in the developing
fetus. Typically, these tests are performed to monitor the fetus’s Down syndrome, a rare
chromosomal abnormality that affects the baby’s developmental and mental development.
A two-mark test is a blood test done during the first trimester between the 11th and 13th
week of pregnancy.

dual marker test

Dual tests were performed with NT scan (Nuchal translucency scan).
Blood tests measure two symptoms such as PAPP-A (pregnancy-related plasma proteins)
and hCG (human chorionic gonadotrophin), while an NT scan measures subcutaneous fluid
behind the baby’s neck.

The results of both tests are tested to see if the child has Down’s syndrome. In the event that
there is a risk of Down’s syndrome, reports indicate abnormal levels of hCG and PAPP-A and
a high NT scan rate. Depending on the results, a pregnant woman may fall into the category
of ‘screen positive or high risk’ or ‘screen negative or low screen’. A quad mark (quad screen)
the test is a blood test done during pregnancy, during the 15th to 20th week of pregnancy.

Similar to the triple screen, the quad marker screen provides information about the risk of
certain birth defects in a child. In this experiment, four markers in the blood were measured
as Alpha-fetoprotein (AFP) produced by the fetal liver, HCG is the hormone produced by the
placenta, Estriol is the estrogen produced by the placenta and fetal liver, and Inhibin -A is
another hormone produced by the placenta.

Worldwide, the average incidence of Down syndrome is between 1 and 1 in 1,100 live births.
Every year about 3,000 to 5,000 babies are born with this chromosome. In the United States,
an estimated 6,000 babies are born with Down syndrome. According to the World Health
The organization, about 60 to 80% of children with Down syndrome have hearing problems. 40
to 45% accounts for congenital heart disease.

Intestinal paralysis also occurs at higher levels
in children with Down syndrome. Some children with Down syndrome, especially those with
a serious heart condition, often fail to develop in childhood.
