What is the hcg level in the blood that indicates pregnancy?

Not only do routine physical examinations now have many new items, but even the numbers in these new items are astronomically difficult to understand. The blood hcg test is a very important test for women, so what is the standard value of blood hcg? What is the blood hcg value in the early stage of pregnancy? What is the blood hcg value that indicates pregnancy?

What is the blood hcg value in early pregnancy

HCG blood test is an important method for early diagnosis of a pregnancy. Because the HCG level in the patient's body during ectopic pregnancy is lower than that during intrauterine pregnancy, a highly sensitive radioimmunoassay method is required to detect the hCG standard value in the blood. So how much is the blood hcg standard worth?

The standard value of blood hCG is <10μg/L, and the standard value of β-hCG is <3.1μg/L. β-hCG is a part of hCG. Generally, the β-hCG radioimmunoassay value of a normal woman is lower than 3.1. If it exceeds 5, the possibility of pregnancy can be considered, and if it exceeds 10, pregnancy can be basically confirmed.

The absolute values ​​of hCG in blood cells vary at different stages of pregnancy and among pregnant women. There is no comparability between them and they can only be compared with each other. During the first three months of pregnancy, hCG levels approximately double every 2.2±0.5 days.

The company stated: μg/L (mg/liter), mIU/ml (milliinternational units/ml), and IU/L (international units/liter) are all possible values ​​that may appear on a blood hCG test report.

It should be noted that some hospitals use ng/ml (nanogram/ml) on their outpatient test forms. This is an old system, 1ng/ml=1μg/L.

Best time to check hcg blood

Everyone has done a physical examination more or less, whether they are still in school or have already entered the society. Physical examination is basically the key indicator to measure whether a person is healthy in today's society. The hcg value can be used to accurately measure whether a woman is pregnant, the duration of pregnancy, and whether it is an ectopic pregnancy. So what is the best time to do a blood hcg test?

Generally, 8-10 days after intercourse, you can test HCG in your blood to confirm whether you are pregnant. This is the earliest and most accurate test method at present. You can also use a pregnancy test strip to check it out 7 days after the menstrual cycle is delayed. It is more accurate. Two green lines appear on the test paper, indicating a positive result, which means pregnancy.

To test whether you are pregnant, the initial method is to go to the hospital for a blood test for HCG test about ten days after having sex. If this indicator value is higher than 10, it can be diagnosed as pregnancy.

This test can be done at any time and there is no dietary restriction requirement, but it is best to have blood drawn on an empty stomach in the morning, as this will give a more accurate result. This test is earlier than the urine pregnancy test to diagnose whether you are pregnant.
