After sexual intercourse, a woman's egg cell is fertilized by a man's sperm, causing the cells to rapidly divide and multiply. The number of cells increases over time, and as the embryo grows, the cells begin to change and differentiate. Some of these cells form the placenta, while others form the baby. The cells that make up the placenta begin to produce human chorionic gonadotropin (hCG), or the pregnancy hormone, in the mother's body.
What is the β hCG hormone?
β hCG gebelik oluşmasını takiben, trofoblastlardan salgılanan hormondur. Human Chorionic Gonadotropin’ in alfa ve beta olmak üzere 2 alt türü mevcut olup, β hCG gebeliğe spesifik olandır. %100’ e yakın gebeliğe spesifik olan β hCG çok nadiren gebelik dışı durumlarda da yükselebilmektedir.
What are β hCG levels during pregnancy?
In a non-pregnant woman, β hCG levels range from 0-10 mlU/ml. With pregnancy, β hCG levels begin to rise within the first 7 to 12 days after fertilization. Pregnancy can be detected at this stage. Throughout pregnancy, β hCG levels generally double every two days. Values then begin to decrease in the later months of pregnancy. However, excessively high β hCG levels suggest molar pregnancy and gestational trophoblastic diseases.
Average β hCG levels by week in a normal pregnancy are: ;
| Number of weeks that have passed since the last menstrual period. | HCG (mIU/ml) (INCIID) |
| 3 weeks | 5 – 50 |
| 4 weeks | 3 – 426 |
| 5 weeks | 19 – 7,340 |
| 6 weeks | 1,080 – 56,500 |
| 7-12 weeks | 7,650 – 288,000 |
| 13-16 weeks | 13,300 – 254,000 |
| 17-24 weeks | 4,060 – 165,400 |
| 25-40 weeks |
In a normal pregnancy, blood levels of βhCG are quite variable. However, if the expected increase in βhCG levels does not occur in the early stages of pregnancy, various problems should be considered. In such cases, unhealthy pregnancy conditions such as chemical pregnancy and ectopic pregnancy should be suspected. βhCG levels can also be elevated outside of pregnancy in cases of cancer or gestational trophoblastic disease.
In conclusion, we hope your β hCG test results will increase to your desired level at the desired time…
