The Principles of Pregnancy Test

When your egg meets with the male sperm, the egg will get fertilized and the fertilized egg is known as zygote or embryo. This embryo after detaching itself from its place will travel and gets itself attached to the inner walls of your uterus. Once the embryo attaches itself with the uterus, your body will start secreting a pregnancy hormone by name HCG (Human Chronic Gonadotrophin) and presence of this particular hormone is a sure sign of your pregnancy.

Today pregnancy tests depend on identifying this HCG hormone to confirm pregnancy and the monoclonal antibodies are employed to detect traces of HCG. The pregnancy test kits come with a stick that when dipped into your urine sample collected will indicate whether or not you are pregnant. When the stick is dipped in your urine sample, preferably the early morning urine, the urine will move up the stick until it reaches the control window, which is an indication that the kit is working. Then the line in the stick will move further up to reach the second window which is an indication that you are pregnant for sure.

Once the stick reacts with your urine the presence of monoclonal antibodies will make the stick to change color thus making the colored line appear in the window provided for the purpose. The test makes use of the presence of HCG in your urine and in the absence of it the stick will show a negative result.
