Beta hCG (β-hCG) result table

ACCESS INFORMATION PRIOR TO THIS POST ON BETA
β-hCG (human chorionic gonadotropin) is a glycoprotein that is initially secreted by trophoblast cells in the embryo shortly after it implants in the uterus. The rapid increase in serum levels of hCG following conception means it is an excellent early indicator of pregnancy. It’s also a parameter which is widely used for monitoring that a pregnancy is progressing correctly.
On a physiological level, hCG triggers the corpus luteum and thus facilitates progesterone and oestrogen synthesis. Progesterone stimulates the maturing of blood and capillary vessels that help the foetus to develop correctly.
hCG levels can be measured in blood or in urine.
Urine tests have a detection limit of 20 to 100 mUI/ml depending on the brand. If the measurement is to be taken in urine, a sample of the first urine of the day is recommended. This is particularly true during the early days of pregnancy because, if the urine is too diluted, the test can return incorrect negative results.
hCG levels in blood can be used to detect levels as low as 5 mUI/ml and the concentration levels of the hormone can therefore be calculated.
hCG levels in multiple pregnancies are 30-50 % higher than in pregnancies where there is only one foetus. However, a multiple pregnancy should be confirmed by means of an ultrasound.
