Pregnancy Test: An Update

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.
