A pregnancy can be confirmed in two ways. One is by the urine test while the other is by the blood test. Both of the tests work by detecting the hCG (human chorionic gonadotropin) that presents in a woman’s body. The placenta produces this hormone once the embryo attaches to the uterine lining. During the first few days after the conception, this hormone’s levels keep building up, triggering those pregnancy symptoms.
A urine test can be performed either at home or at the doctor’s. There are two ways to carry out a urine test. The first one is to collect your urine in a container then dip the stick into the substance. The second way is to place the stick into your urine stream. Each technique takes a different period of time to see the result. The result will come out as a change in color, a line or a symbol. In some new types of digital test, they can also show “pregnant” or “not pregnant”.
When is suitable to take the urine test?
It is suggested that a pregnancy test should not be done until your period comes late at least one day. This is the time when your pregnancy enters its second week. However, there are other tests which are sensitive enough to detect your pregnancy earlier.
Is the urine test accurate?
If done in the correct procedure, home pregnancy tests’ accuracy, including a urine test, is about 97%.
Advantages of the urine test:
- Can be done at home
- Easy to use
- Is low cost
- Keeps your privacy
- Gives quick result
Disadvantages of a urine test:
A urine test can give false result if you don’t follow the instruction correctly. Thus, if your urine test comes out with a negative result by you still develop symptoms of pregnancy, there is a chance that you have actually conceived. Contact your doctor for a check-up or wait a week then retake the test. Symptoms of a pregnancy include missed periods, fatigue, sensitive breasts, nausea, etc.
In totally, there are two types of blood test which are a quantitative blood test and a qualitative blood test. In a quantitative blood test, the doctor will measure the exact amount of hCG in your blood while in a qualitative hCG blood test, you will receive just a “yes” or a “no” for your baby’s presence.
Advantages of the blood test:
- Detect the pregnancy earlier compared to a urine test. (it can tell if you are pregnant or not just 7 to 12 days after the conception, if any)
- Tell the exact amount of hCG in your blood. (through this statistic, your doctor can know if you’re having any problems with your pregnancy.)
Disadvantages to having a blood test done:
- Must take place at the doctor’s place
- Is expensive (compared to a urine test)
- Takes more time to give the result
