A blood test for human chorionic gonadotropin
To diagnose pregnancy at an early stage, you can take a blood test for HCG. This method is considered to be one of the most accurate. Human chorionic gonadotropin - a hormone that begins to be produced in the woman's body immediately after the implantation of a fertilized egg in the uterine wall.
Diagnosis of growth the level of HCG in biological fluids allows to speak about occurrence of pregnancy. In rare cases, the hormone levels can rise for other reasons. This is a sign of serious disorders in the body and requires immediate medical diagnosis and subsequent treatment.
First and foremost, human chorionic gonadotropin, it is possible to determine in the blood. A few days after conception the concentration of hormone in this biological fluid starts to rise.
Implantation of the embryo into the uterine wall occurs a few days after conception. Thus, a blood test for HCG can be carried out 5-7 days after intimacy. If pregnancy is achieved, the analysis will certainly show.
To donate blood for HCG is possible in the antenatal clinic, family planning centre or in a special laboratory. The result of the analysis will be known very soon. It should be noted that this diagnosis is paid. Free analysis can do only by referral from the gynecologist.
Diagnosis of pregnancy at home
The level of human chorionic gonadotropin in urine after successful fertilization, increases at a much slower pace than in the blood. To pregnancy can be diagnosed by using test strips that are sold in every pharmacy, it is necessary to analyze not earlier than 2 weeks after the sexual contact.
Given the fact that ovulation usually occurs in mid-cycle, diagnosis of pregnancy using a standard test you from the first day of menstruation.
The test can be done earlier. In many cases, the pregnancy may already 7-10 days after conception. It should be remembered that in this case the probability of obtaining a false negative result is too large. If the test appeared only one band, you need to wait the beginning of menstruation and to make Express-analysis again.
The level of HCG in biological fluids will increase daily. If a woman doubts in the negative result of the analysis, it can repeat it every 2-3 days.
Advice 2 : How to increase HCG in early pregnancy
Chorionic gonadotropin begins to be produced in the woman's body immediately after the implantation of a fertilized egg in the uterine wall. During the first half of pregnancy the concentration of this hormone in the blood is constantly increasing.
Human chorionic gonadotropin is a hormone that begins to produce in a woman's body during pregnancy. Before the concentration of HCG in the blood is only 0-15 honey\ml. Immediately after the implantation of a fertilized egg content of the hormone in biological fluids begins to grow rapidly.
Levels of human chorionic gonadotropin in the blood and urine are totally different. Increase in blood concentration can be detected much faster than in urine. If a woman is very important to diagnose pregnancy in the early stages, it can pass blood test. Diagnosis is possible in only a few days after fertilization.
Standard pregnancy tests in the form of strips, which must be dipped in urine, can be used only from the first day of menstruation, but not earlier. If you do analysis before, the probability of obtaining a false negative result.
There is a timetable for increasing the level of HCG in the blood within normal limits. It is believed that each week the concentration of gonadotropin should increase by approximately 2-3 times compared to its previous value. But this is only an approximate growth rate.
10-12 days of pregnancy the level of HCG in blood is 100-150 honey\ml. in a week this will increase to 200-400 honey\ml At 4-5 weeks of pregnancy, the concentration of the hormone in the blood should be 2560 — 82300 honey\ml.
The level of HCG grows rapidly during the first trimester of pregnancy. Around 12 weeks the growth rate slowed down, and at 16 weeks the concentration of the hormone remains unchanged or begins to decline.
If the growth rate of the concentration of HCG in biological fluids do not conform to the norm, this may indicate the presence of certain pathologies. For example, the slow growth of the levels of hormone in the blood can be a sign of ectopic pregnancy, as well as the existing threat of miscarriage. The decrease in the concentration of HCG in biological fluids during the first trimester of pregnancy may indicate fetal death.
Blood to determine the level of HCG can be taken in the antenatal clinic. In most clinics it is paid.
Women who already have the sad experience of miscarriage, should be regularly to donate blood to determine the concentration of HCG. This will help to identify certain types of abnormalities in the earliest stages of their development.
