Is hcg dilution the same as hcg value?

In clinical tests, in order to determine whether a woman is pregnant, we will choose to conduct some blood and urine tests. We are very confused about some of the terms in the test form and cannot distinguish some of them. So are hCG dilution and hCG value the same?

Is the hcg diluent the same as the hcg value?

There is no objective difference between the diluted hCG value and the hCG value. Everyone should know that when checking the hCG value in the early stage, it is mainly to determine whether you are pregnant or whether it is a normal pregnancy test. The hCG value will continue to increase as the pregnancy period of the pregnant woman increases. After the increase, the concentration of blood hCG value will also increase. Therefore, when checking the hCG value in the middle and late stages, you must use diluted solution, because the concentration is too high, which will also affect the test results of the hCG value. The comparison of this diluted solution is also based on the blood hCG concentration. Everyone does not need to think too much or worry too much. Try to relax as much as possible during pregnancy. In fact, this is a problem that doctors should consider, and it is normal for everyone to want to understand it clearly.

The difference between the dilution hcg value and the hcg value in the early and middle stages is very large. They increase every day, and in the middle and late stages they increase by hundreds of thousands of times. Generally, when the dilution hcg value reaches 5000 or above, dilution is required. The increase rate is rapid, and it may double every day. This does not mean that the baby is unhealthy in the belly, and everyone does not need to worry too much. This is all normal. On the contrary, no increase or the test value does not meet the test standard is an abnormal manifestation.

The hcg value of the diluted solution is lower than that of the undiluted solution, and the HCG quantitative analysis is accurate. In the first three months of pregnancy, the doctor will do this kind of examination for you according to your condition. If everything is normal in the middle and late stages, there is no need for examination. The doctor mainly considers whether the condition is stable.

hCG values ​​over time

At present, the more common measurement methods in clinical medicine are the following three: enzyme-linked immunosorbent assay (ELISA) screening method, chocolate enzyme immunoassay method, and immunocolloidal gold method. These methods have good sensitivity, low cost, and fast testing, and are widely used in clinical medicine.

Human chorionic gonadotropin enters the maternal blood after fertilization and multiplies rapidly until the 8th week of pregnancy, then slowly decreases in concentration until the 18th to 20th week, and then remains there for a long time. Generally, a level of at least 2.5 MoM of human chorionic gonadotropin is associated with Down syndrome. However, the actual human chorionic gonadotropin level in the maternal blood of DS patients is only 1.3 MoM on average, which cannot significantly distinguish DS patients. The human chorionic gonadotropin-related molecules used for DS testing include dispersed b-hCG and high-sugar and high-calorie hCG (H-hCG).

The level of human chorionic gonadotropin-related molecular structures is also related to the identification of fetal sex. The level of human chorionic gonadotropin in baby girls is significantly higher than that in baby boys. All human chorionic gonadotropin is produced by the transformed germ cells of the embryonic hCG. Human chorionic gonadotropin is produced by a fusion of germ cell transitional somatic cells and germ cells. Human chorionic gonadotropin begins to be metabolized 10-14 days after pregnancy.
