and a family history of birth defects.


A double marker test is a blood test and ultrasound which is given to pregnant women. To
find out any chromosomal malformation in the fetus. This test is also conducted because it
plays a major role in finding neurological conditions in the fetus like Edward’s Syndrome
and another kind of down’s syndrome and etc. Chromosomal abnormalities can result in major
problems in post-baby born but it’s extremely rare.

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
discussed.
