Early pregnancy blood test

Women want to know about a possible conception early. In some, this is caused by a great desire to become a mother. Others, on the contrary, worry because they do not want to have a baby yet. Many people use tests purchased at a pharmacy. However, women should know what blood test shows pregnancy. This method is the most reliable. This method is based on determining the value of human chorionic gonadotropin (hCG). It is also called the pregnancy hormone.

How to take a blood test for pregnancy in the early stages?

HCG is found in the blood of only expectant mothers. This hormone is produced by chorion - the envelope of the embryo. According to its level, it is determined whether a conception occurred. This research is carried out by many laboratories. A woman should know what is called a pregnancy test - a blood test for hCG.

You can come to the medical institution approximately 8 days after the alleged conception. Doctors may recommend retaking the test in a few days. If conception has occurred, then the level of the hormone will increase. Only to pass the research is desirable in one laboratory.

During the procedure, venous blood is taken. You need to give it in the morning, on an empty stomach. You can go through the procedure at another time. In this case, you can not eat about 6 hours before manipulation.

How to determine the pregnancy on the basis of the blood test for hCG?

For men, as well as non-pregnant women, the level of the hormone is normal - from 0 to 5 honey / ml.

But if the conception has occurred, the interpretation of the blood test during pregnancy depends on the timing of gestation. HCG rises to about 12 weeks. Then it starts to decrease. At week 2, the hormone level can be in the range 25-300 MED / ml. By the 5th week, its value falls on the interval from 20,000 to 100,000 dl / ml. It is important to remember that norms vary slightly in different laboratories. It should also be taken into account that the parameter depends on the characteristics of the organism of each woman. However, the approximate values ​​can be viewed by special tables.

An experienced physician, this study can provide other useful information about the patient's health. An increase in the value of human chorionic gonadotropin can indicate the following conditions:

• waiting for twins or triplets;
• a disease called bladder drift;
• tumors of internal organs;
• the gestation period is longer than expected.

If the hCG is below the accepted norms, then it can say about this:

• ectopic, as well as frozen pregnancy;
• a shorter gestation period than expected;
• possible miscarriage.

If HCG does not increase, but decreases, it will require a mandatory visit to the doctor.

Some drugs can affect the result of the study. These are the drugs that contain this hormone in their composition. They include "Pregnil", "Horagon". These medications are prescribed for infertility therapy, as well as for the stimulation of ovulation. Other drugs do not affect the value of hCG.

Sometimes the result of the research can be false-negative. An error is possible if the woman had late ovulation or implantation.

Other examinations in the first weeks can not show if fertilization has occurred. Some girls are looking for an answer to the question of whether a common blood test can show pregnancy. The answer is no. The results of this test can not determine the onset of conception. But this study of future mothers will have to be done regularly until the birth. Deciphering the general analysis of blood during pregnancy has its own characteristics, which every qualified doctor knows. Therefore, you should not try to draw conclusions from the test results on your own.
