There are several methods for early diagnosis of pregnancy. The most accurate of these is a blood test for hCG. It can be performed within a few days after conception. The method for determining the level of chorionic gonadotropin in urine is also considered quite accurate.
Chorionic gonadotropin blood test
In order to diagnose early pregnancy, you can take a blood test for hCG. This method is considered one of the most accurate. Chorionic gonadotropin is a hormone that begins to be produced in a woman's body immediately after the implantation of a fertilized egg into the wall of the uterus.
Diagnostics of the increase in the level of hCG in biological fluids allows us to talk about the onset of pregnancy. In rare cases, hormone levels can rise for other reasons. This is a sign of serious disturbances in the functioning of the body and requires immediate medical diagnosis and subsequent treatment.
First of all, chorionic gonadotropin can be determined in the blood. Within a few days after conception, the concentration of the hormone in this biological fluid begins to increase.
The embryo is implanted into the wall of the uterus within a few days after conception. Thus, a blood test for hCG can be performed as early as 5-7 days after intimacy. If pregnancy has come, the analysis will definitely show this.
You can donate blood for hCG in an antenatal clinic, a family planning center or in a special laboratory. The result of the analysis will be known very soon. It should be noted that this type of diagnostics is paid. A free analysis can be done only if there is a referral from a gynecologist.
Diagnosing pregnancy at home
The level of human chorionic gonadotropin in the urine after successful fertilization rises at a much slower rate than in the blood. In order for pregnancy to be diagnosed using test strips, which are sold in every pharmacy, it is necessary to conduct an analysis no earlier than 2 weeks after sexual contact.
Given that ovulation usually occurs in the middle of the cycle, pregnancy can be diagnosed using a standard test from the first day of missed periods.
The test can be done earlier. In many cases, pregnancy can be determined as early as 7-10 days after conception. It should be remembered that in this case the probability of getting a false negative result is too high. If only one strip appears on the test, you need to wait for the onset of the delay in menstruation and do the express analysis again.
The level of hCG in biological fluids will increase daily. If a woman doubts a negative test result, she can repeat it every 2-3 days.
