Pregnancy
Test: An Update
Do
you know?
The
earliest written record of a pregnancy test was found in an ancient Egypt
document. It was a urine based pregnancy test of 1350 BCE.
Interesting
Fact: In this test a pregnant woman urinate on wheat and barley seeds for
several days. If the wheat grows it reflects that the pregnant woman is
expecting a female child and if barley grows, she is expecting a male child. On
the other hand if both not grow she is not pregnant at all.
The
theory was tested later in 1963 and found that 70% of time this found true.
Till
that many researches are carried out. In 1890 many scientist start testing the
chemicals of internal secretion by certain organs. In 1903 they identified the
hormone that had the role in female reproduction.

Now
we have a standard test kit which detects hcg (Human Chorionic Gonadotropin)
hormone to clear accurately that a woman is expecting or not.
The
whole procedure to test the pregnancy is as follows:
To
confirm your pregnancy with the standard pregnancy test kit:
1) Buy a home pregnancy test kit from a medical
shop.
Test your pregnancy at least one day after
your missed period. Before taking a home pregnancy test, though waiting a week
is considered best.
2) Collect midstream sample of your urine in the cup
provided with your test kit.
3) Use the dropper to place a few drop of urine onto
the test stick and wait for 1 to 5 minutes., though some tests may take up to
10 minutes to give an accurate result.
4) Check the results by following the instructions
mentioned on your pregnancy test kit.
If
the results are positive you should make an appointment with your doctor to
confirm your pregnancy.
After
2003 the next generation digital home pregnancy test kit was approved by FDA of
Clearblue Eye’s Brand.
It
was an advanced pregnancy test with weeks estimator. Actually it uses two
strips instead of single strip. One detects the hormone hcg (Human Chorionic
Gonadotropin) produced by woman if she is pregnant. After fertilization the
level of hcg varies significantly first it increases then start declining.
So the second strip measure the
level of hcg to detect the length of
pregnancy, whether it falls in 1-2, 2-3 or 3++ week.
