Many girls in their own test paper to check whether they are pregnant or not, will choose to go to the hospital to carry out some accurate checks, such as to the hospital for blood tests and so on some of the checks, but the results of the blood test came out, a lot of people can not read, and do not know how to be pregnant, and how long the pregnancy, a lot of people know that it is to look at the hcg but how much hcg blood test to be counted. The first thing you need to do is to get a good deal on your own.

How much blood hcg is considered early pregnancy

The normal value of blood hCG < 10 μg / L, the normal value of β-hCG < 3.1 μg / L. β-hCG is a part of the hCG, the general normal women's β-hCG exemption determination value of less than 3.1, if more than 5 can be considered to be conceived, if more than 10 basically to determine the pregnancy.

The absolute value of serum hCG varies greatly between different periods of pregnancy and between pregnant women, and is not comparable to each other, but only to themselves. In the first three months of pregnancy, hCG levels double every 2.2±0.5 days.

Blood hCG levels during normal pregnancy:

Normal value for gestational week (IU/L) Risk

0.2-1 week gestation 5-50 At this point in time there is almost no change in blood hCG values and the risk is not considered for now.

1-2 weeks of pregnancy 50-500 every 2 days blood sampling results in β-hCG growth of not less than 66% should be considered ectopic pregnancy and other possibilities.

2-3 weeks 100-5000 ditto

3-4 weeks 500-10000 ditto

4-5 weeks 1000-50,000 days after pregnancy hCG can rise to more than 2500IU / L, if lower than this value, there may be a risk of preterm miscarriage.

5-6 weeks of pregnancy 10000-100000 sudden and sharp drop need to be alert to intrauterine fetal growth retardation or pregnancy diseases, etc..

6-8 weeks 15000-200000 as above

2-3 months 10000-100000 peaked and partially dropped, but still higher than when not pregnant.

Unit descriptions: μg/L (micrograms per liter), mIU/ml (milli-International Units per milliliter), and IU/L (International Units per liter) are all units that may appear on a blood hCG checklist.

The latter two units are more widely used at present. mIU and mU are the same (the I in the middle of mIU means "international"). That is, 1U/ml=1000mIU/ml=1000mIU/ml, in which due to the different values of the experiment, the three conversions are as follows: 1000IU/L=1000mIU/ml==1μg/L×conversion coefficient.

It should be noted that some hospitals checklist unit is ng/ml (ng/ml), which is the old system of units, 1ng/ml = 1μg/L.

hCG (chorionic gonadotropin) is the obstetricians and gynecologists are familiar with and most often used pregnancy test "hormone. It is the most commonly used pregnancy test hormone by obstetricians and gynecologists.

It is composed of glycoproteins of alpha and beta dimers. However, the alpha-subunit is ****owned by the anterior pituitary hormone, and the beta-subunit is specific for hCG.

What is the normal value of progesterone? Take a look at the normal reference values:

Weeks of gestation hCG (IU/L)

0-1 week 5-50

1-2 weeks 50-500

2- 3 weeks 100-5000

3-4 weeks 500-10000

4-5 weeks 1000-50000

5 -6 weeks 10,000-100,000

6-8 weeks 15,000-200,000

February-March 10,000- 100000
