The completed HCG is produced by the placental chorionic and syncytiotrophoblastic layer. Do the test as early as 7 days after sex life by using a pregnancy test strip (pregnancy test kit). It is recommended to test after 11 days, the later you do the test, the more accurate result you get.
Today I would like to introduce how is HCG produced in pregnant women? And what time is the earliest point of detection of pregnancy?
Today, we will explain the process of conception and the production of HCG with the schematic diagram of uterine and fallopian tubes. Today, we will explain the process of conception and the production of HCG with the schematic diagram of uterine and fallopian tubes. During ovulation, it takes about 24 hours for sperm to reach the fallopian tube and combine with the ovum. After passing through the ovary, the ovum is grabbed by the tubal umbrella and enters into the fallopian tube. The ovum travels to the ampulla of the fallopian tube, and the sperm travels through the vagina, the cervix, the uterine cavity, and then to the fallopian tube,where fertilized with an volum in the ampulla of the fallopian tube. This process takes up to 24 hours, with fertilization remaining for 30 hours while the cells divide.It will enter the uterine cavity on the fourth day, and keep on dividing on the fifth to sixth day and enter into the proper position. Implantation was initiated on 7th to 8th day and completed on 12th day after fertilization. The fertilized ovum produces a small amount of HCG after implantation, which means that HCG appeared on the seventh day.
But at this time, morning urine is the best one to do early pregnancy test, because the concentration of HCG is very low at this time. The concetration of morning urine is also the closest to the HCG in the blood. HCG concentration can be measured in the seven days (the test kit can detect). It is recommended to test after 11 days because the concentration is a little lower. The longer the time is, the higher the concentration is, and the test results will be more accurate.
