Advice 1: As HCG increases in pregnancy

Human chorionic gonadotropin is a hormone that begins to be produced in the woman's body immediately after a fertilized egg embeds itself in the uterine lining, and pregnancy can be considered valid. At first, the amount of this hormone so small that to prove its existence only by means of a special blood test, but every day its concentration is increasing.
As HCG increases in pregnancy

Human chorionic gonadotropin

In the body of non-pregnant women HCG is either absent altogether or present in such small quantities (less than 2 mIU\ml) that its value can easily be neglected. But it's worth it to be pregnant as the situation cardinally changes. Already in 6-9 days after fertilization, the concentration of the hormone in the blood reaches this magnitude, looking at that, you might suspect the onset of
pregnancy. The concentration of HCG in the blood rise very quickly, it increases every 2 days at least twice and after 1-2 weeks after fertilization, i.e. 3-4 weeks after the start of the last monthly bleeding, reaches the value of 25 mIU\ml and more. Between 8 and 12 weeks the concentration of hormone in the blood reaches its maximum and can go up to 289000 mIU\ml, and then decreases gradually and remains low until birth, after which HCG again disappear from the blood almost completely.

The rise of HCG in a woman's urine occurs in a similar scheme with the only difference that its concentration is always lower than blood, so the usual tests from the pharmacy to establish the fact of pregnancy is somewhat later, for about a week, that is just by the time delay of the menstrual cycle.

Table HCG

Someone who would like to visualize exactly how there is a rise of HCG in the blood, it may be advisable to use the following table:
Week of pregnancy ------ the Level of HCG in mIU\ml
3 - 4 --------------------------- from 0 to 130
4 - 5 --------------------------- from 75 to 2.600
5 - 6 --------------------------- from 850 to 20.800
6 - 7 --------------------------- from 4,000 to 200,000
7 - 12 -------------------------- from 11.500 to 289.000
12 - 16 ------------------------ от18.300 to 137.000
17 - 29 ------------------------ from 1.400 up to 53,000
30 - 41 ------------------------ from 940 up to 60,000

From this table it can be seen why steel possible things, when the woman has a nice belly as a joke or seriously checks my urine pregnancy test and gets a negative result. The test does not look at the stomach, it determines the concentration, and by the end of pregnancy, it can decline so much that it is not enough to trigger the test reagent.

You can also see that the scatter of the values in the table are quite high, therefore, based on the analysis, to determine the exact duration of pregnancy is quite problematic. That is 10000 mIU\ml can be defined as the end of the 5th week and beginning of 8-9. This means that to determine the period it is better to use some other method, such as ultrasound.

Advice 2: How to calculate hCG on the term

During pregnancy a woman's body continuously produces the hormone human chorionic gonadotropin or HCG. This is responsible for the alteration of an organism of the expectant mother, so his level to judge the duration of pregnancy. The converse is true: depending on the period of pregnancy the level of HCG in the body varies considerably.
How to calculate hCG on the term
After conception, the cells that form the placenta begin to produce the HCG hormone. For the first time to lock it in the blood of pregnant women by 11 days after conception, in urine on day 14. It is his discovery is based the principle of popular home tests for pregnancy.

The mechanism of the process

It is believed that pregnancy is diagnosed if the level of HCG more than 25 mIU/ml. If its normal for the amount of the hormone increases like an avalanche: the level of beta-HCG doubles every 2-3 days. In multiple pregnancies the amount of the hormone is proportional to the number of kids increase at a faster pace.

To calculate the level of the hormone depending on the duration of pregnancy, it is possible to focus on average values:
- <5 mIU/ml: non-pregnant women;
- 5-50 mIU/ml: a period of 3 weeks;
Is 5-426 Miu/ml: minimum 4 weeks;
- 18-7340 Miu/ml: 5 weeks;
- 1080-56500 Miu/ml: minimum of 6 weeks;
- 7650-229000 Miu/ml: duration 7-8 weeks;
- 25700-288000 mIU/ml 9-12 weeks;
- 13300-254000 mIU/ml: the period of 13-16 weeks;
- 4060-165400 mIU/ml: the period of 17-24 weeks;
- 3640-117000 mIU/ml: a period of 25-40 weeks.

It should be remembered that the numbers can vary: it is important not only in itself a numeric value, but the trend of its changes.

As you can see, 6-7 weeks after conception levels of HCG stabiliziruemost, and after 12 weeks slowly decreasing. It is on this depending on the amount of the hormone of pregnancy is based the principle of operation is very popular with moms-to-be calculator of HCG.

How to use the calculator HCG?

First of all, it is very convenient to interpret the results of laboratory blood tests the amount of HCG in the body, and also to analyze the growth level of HCG. For calculation of growth hormone in program-calculator entered information about the level of hormones in the first test and the number of days after ovulation, the hormone levels in the second test and the number of hours between the 2 tests done.

Calculator calculate the doubling time of HCG and the difference between the number of hormones for 2 days. The resulting value must be within the following ranges:
- 1200 Miu/ml for 36 to 72 hours;
- 1200-6000 Miu/ml for 72-96 hours;
- over 6,000 Miu/ml over 96 hours or more.

There are several reasons why HCG levels may deviate from these values:
- higher values are usually associated with multiple pregnancies, it is wrong to a certain period, pathological course of pregnancy;
- lack of growth HCG sometimes indicates a dysfunctional development of pregnancy, in particular the threat of miscarriage, as well as the fading of the fetus.

Advice 3: 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.
How to increase HCG in early pregnancy
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.
Useful advice
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.
