Beta hCG (β-hCG) result table

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.

Choosing a fertilisation technique when oocyte counts are poor. IVF or ICSI?

A low ovarian response is an increasingly common situation for clinicians. It is mainly associated with delayed motherhood and, accordingly, with lower ovarian reserves. In this type of patients, the number of oocytes retrieved after puncture is normally limited. In this situation, choosing the most adequate fertilisation technique, conventional IVF or Intracytoplasmic Sperm Injection (ICSI), may stir a little controversy (of course, provided that the sperm quality and the medical history lead us to consider conventional IVF as a reasonable option). […]

BETA pregnancy confirmation after IVF or other reproductive techniques

What is a Beta?

The determination of the levels of the hormone beta-hCG in blood. The hormone produces the embryo and passes to the mother via the placenta. This is the first measurable sign of embryo implantation. […]
