Pregnancy tests are performed to confirm if you are pregnant or not. These tests can be done by testing your urine and blood. When to take the pregnancy test explains when and how early you can take this test.

The urine test to see if you are pregnant or not can be done at home. Since this test is done at home, it is also called the home pregnancy test.

Blood testing for pregnancy is more sensitive and elaborate and has to be performed in a laboratory.

How Do Pregnancy Tests Work?

Urine and Blood Pregnancy tests detect pregnancy by identifying a hormone called human chronic gonadotropin (hCG), which is present in blood and secreted in urine during pregnancy. This hormone is also called the pregnancy hormone.

HCG is a glycoprotein hormone or marker, which is produced at higher levels in the body when a fertilized ovum gets implanted on to the wall of the uterus.

This happens usually 6 to 8 days after conception, which is 20 days after the last menstrual period in a woman who has a regular 28 day menstrual cycle.

This implantation takes place about six to eight days after the sperm has fertilized the ovum but it is known to happen even much later.

HCG is produced during early pregnancy by the embryo after conception and later by the placenta. Levels of hCG in the body rise rapidly doubling every 2 to 3 days as the pregnancy progresses.

Home or urine pregnancy test

Home pregnancy test is a convenient and easy to use method to test yourself for pregnancy at home if you have missed a period.

The urine pregnancy kit, which is available at most drug stores without prescription, offers explicit instructions, which you can follow and do the test yourself.

Additionally, it offers the advantage of convenience, privacy and being inexpensive. You can then see your doctor if the test is positive for advice, or if the test is negative for more sensitive tests. Read home pregnancy test for a full note.

The urine pregnancy test gives the most accurate result in the week following your missed period and boasts of 97% accuracy.

Blood test for pregnancy

Pregnancy blood tests are done in a laboratory and not at home. A blood sample is drawn from the vein on the inner side of the elbow or it may be drawn from the back of the hand.

Blood pregnancy tests are more sensitive and can detect lower levels of the hCG hormone and pregnancy earlier than the home pregnancy urine test.

This test can give a result about a week after the ovulation day – that is even before you would know whether you will miss your period or not. Additionally, blood tests are more accurate and boast of 99% accuracy.

This helps to satisfy the anxiety of an over anxious mom–to–be. Read pregnancy blood test for a full note.
