When can I do a blood pregnancy test

Many of you wonder how long to wait to do a pregnancy test with a blood test and that the result is as accurate as possible. However, it is convenient to know that there is no single answer to this question, since it depends on the cycle of each woman, but normally there is a cycle that oscillates in the 28 days in most, so the positive result does not vary much from a few to others.

The blood pregnancy test can be done from the first week after ovulation, although it is recommended to wait for a delay in menstruation because hCG levels are higher and pregnancy tests will be more reliable.

The Chronic Gonadotropin hormone (Beta hCG) It is a hormone that is produced during pregnancy by part of the placenta. Its main function is to prevent the corpus luteum of the ovary from disintegrating and to maintain progesterone production.

When you take a pregnancy test, such as the urine test or pregnancy test or the blood test, the hCG levels are measured. This hormone increases from the implantation of the embryo in the uterus and can be detected in the blood from two weeks after ovulation.

There are not many differences between the blood and urine pregnancy tests, but there are some advantages of the blood test over the urine test. In both, hCG levels are detected, but for its detection, in blood testing takes less time, since small amounts of this hormone can be detected and it also allows you know how old the fetus is. The value of this hormone also allows you to know if the pregnancy is developing normally. For the urine test it is necessary to be fasting while for the blood test it is not.

Many women have complete confidence in the blood pregnancy test, but although it is not frequent, blood tests to see if you are pregnant may fail in the following cases:

• If it is done very early. Sometimes the desire to know if you are really pregnant leads you to take the pregnancy test ahead of time and this can be an inconvenience since you could find a false positive.

• If you have a hormonal problem and you are aware of it, you should consult your doctor in case this problem could affect hCG.
• It may happen that the site where you have carried out the test does not have the materials or the necessary conditions to carry out a correct analysis, but in order not to lose customers what they do is make discounts so it can be an economic advantage but a disadvantage to the time of result.
