When to do the blood pregnancy test
Although the most used method to find out if there is a pregnancy is home tests using urine, the reality is that many women continue to opt for the blood test, among other things, because it is much more reliable and accurate.
The method they detect pregnancy is very similar, both in blood and urine, since both do so by detecting the presence of hCG, the chorionic gonadotropin hormone, popularly known as the pregnancy hormone. The blood test is much more reliable than the urine test because it can detect up to 1mIU / mL, while for the urine test to detect it, on average, there must be at least 20 mIU / mL.
With the blood test, we can already detect it from the first moment in which the embryo makes the implants in the uterine walls, and the woman’s body already begins to secrete this hormone. In addition, this pregnancy test not only tells us if it exists or not, but we can also obtain information such as the exact age of the fetus, if there is an ectopic or molar pregnancy or if there is a possibility of spontaneous abortion.
From what day can a pregnancy test be done?
Indeed, when we talk about the pregnancy test, most of them already think of the urine test, which has become popular in recent decades thanks to its easy acquisition in pharmacies and its speed. It can also be done quietly at home. If you are going to use this method, we recommend buying one of the most sensitive ones, since in this way you will avoid giving a false negative as much as possible. In recent years, all brands have become relatively equal, and, right now, the vast majority already detect levels from 20 mIU / ml.
If you wonder when to do the pregnancy test by this method, you should know that the answer will vary depending on the regularity with which your menstruation arrives. If you are a regular person in this regard, calculating the best time to take the test will be much easier. In this case, you will have ovulated in the middle of the menstrual cycle, and implantation will occur between 6 and 10 days after the egg has been fertilized.
Considering your regularity, a single day behind the date on which it should have arrived, the levels of beta hCG, the chorionic hormone gonadotropin, will have already begun to rise, reaching levels in urine that the pregnancy test home can already detect.
Although there are brands that advertise their products saying that one week after conceiving, they already give reliable results, you should wait until you are at least one day late. In the same way, although you can do it at any time of the day, it is best to do it with the first urine in the morning, when the levels of this hormone are more concentrated.
After taking the home pregnancy test, you can now visit the doctor to do the blood test, at which time there will be no doubt about your pregnancy.
When is it more reliable to do a pregnancy test?
As mentioned in the previous section, doing the home pregnancy test at least one day after the delay is recommended. Still, for more excellent reliability, we recommend that you follow the following indications:
The reliability of urine tests increases as time passes, or what is the same, as the presence of the pregnancy hormone increases. If your period is regular, we advise you to wait three days after the delay and if it is negative, wait a few more days before repeating it.
The time when the pregnancy tests are most reliable is ten days after the delay. Depending on which women, it is possible that the hCG does not present the minimum detectable levels during the first week. If you have taken a test and it has been negative, we recommend that you wait until this tenth day before trying again. In this way, the result is much more reliable.
Pregnancy test before the absence
The days in which a pregnancy is suspected, whether it is something desired or not, are days that pass with enormous nervousness, and the woman lives with immense intrigue and wants to clear the doubts as soon as possible. This impatience can cause you to take the pregnancy test too early, missing the result.
Taking the pregnancy test ahead of time is likely to run into a false negative. Let it come out that you are not when you are indeed pregnant. This happens because, in different cases and women, hCG may take time to increase its levels significantly, so they are invaluable for the test.
Therefore, if the pregnancy test has been negative, but the lack of menstruation persists, you must repeat the trial following the instructions that we have explained in the previous sections.
It is also possible that you believe that your period has dropped when it has not, causing your pregnancy to progress without you being aware of it. The culprit for this is implantation bleeding, a sign of pregnancy that can be disguised as menstruation. However, unlike the rule, this bleeding is lighter, brown, and usually lasts between 1 and 3 days. In the following article, we will talk more about implantation bleeding.
