A pregnancy test is done to determine if you are pregnant or not. In this, you check for the presence of a hormone, called human chorionic gonadotropin (HCG), in your body. HCG is only produced during pregnancy. The placenta in the woman’s body starts producing them after the fertilised egg attaches to the walls of the uterus. Once your body starts producing it, the level of HCG rises very quickly, doubling every two to three days.
There are two ways you can take the pregnancy test: through urine, or blood, in both of which the presence of HCG is checked. The urine pregnancy test is generally taken a week after you miss your period. It can be taken under medical supervision or at home and is accurate 97-99% of the time. The blood urine test is taken in a medical centre. Through this, even a very small amount of HCG can be traced. It is quick and efficient as it gives the result before the urine test result, and even before you miss your period. It has an accuracy rate of about 99%. It is generally taken to confirm the urine test result.
As you already know, there are two types of pregnancy tests: blood and urine. Now, let us look at them one by one:
This has to be taken in a clinic. A small amount of blood is drawn from the veins of your arm and is then sent to a lab for testing. A blood pregnancy test is of two types:
You can take the urine pregnancy test at home or at the doctor’s office. Both work the same way. If taking one at a clinic, you will be required to pee in a cup. The doctor will then use a kit, similar to a home pregnancy kit, to determine the presence of the HCG hormone, to confirm if you are pregnant or not.
You should take a pregnancy test if you think you are pregnant. Here are some early signs of pregnancy:
You can get a home pregnancy test at a medical store and you do not need a prescription for it. It is inexpensive and widely available. Most home pregnancy test kits have a device called a dipstick. They might also contain a collection cup. These tests are accurate 97% of the time. However, it might give a false result, generally if taken too soon after you miss your period. Hence, do note that you should wait for at least a week after you miss your period before taking a pregnancy test.
If your pregnancy test result comes out to be positive, it means you are pregnant, and vice versa. If positive, you must immediately see a doctor understand what to do next and how to prepare. The negative test result means you are not pregnant. In that case, too, it might be good to see a doctor to understand why you missed your period. There can be several reasons behind a missed period:
Although both urine and blood pregnancy tests are accurate over 97% of the time. However, there is still a 3% chance that it might come out to be false.
In some cases, the home pregnancy test might give a positive result, even if the woman is not pregnant. Here are some of the possible reasons behind it:
Just as the home pregnancy test kit can give a false positive, it can give a false negative result too. Here are some of the possible reasons behind it:
If even after the negative result, your instinct says you are pregnant, you should always trust it. Take another pregnancy test, or visit the doctor to get the blood pregnancy test, which is more accurate. Also, treat yourself as pregnant until you are completely sure.
