Difference Between HCG and Beta HCG

Almost every woman dreams of becoming a mother, this desire is inherent in her by nature. But how to determine in the early stages whether she is pregnant or not? For this, there are special laboratory tests, one of which is a blood test for hCG (human chorionic gonadotropin). Today, it is customary to distinguish between two fundamentally different blood tests for human chorionic gonadotropin: hCG and beta-hCG. The thing is that hCG consists of two subunits: alpha and beta. And today we will try to figure out what is the difference between them.

Definition

Subunit Alpha-hCG corresponds to similar subunits of the pituitary hormones LH, FSH, TSH. In other words, the presence of this hormone in the blood can be caused not only by pregnancy, but also by some hormonal disorders.

The subunit beta-hCG is unique, which is why it is of decisive importance in the diagnosis of pregnancy. Such a hormone (beta-hCG) is produced exclusively by the cells of the membrane of the embryo.

Comparison

A blood test for chorionic gonadotropin makes it possible to diagnose pregnancy as early as 7-10 days after fertilization, in urine this hormone is determined somewhat later. It is very important and necessary for the body during the entire period of pregnancy, for example, in male infants, hCG stimulates Leydig cells. These cells are responsible for the synthesis of testosterone, which is involved in the formation of the male genital organs and also affects the adrenal cortex of the unborn baby.

  1. hCG is a hormonal subunit that can appear in a woman's body during pregnancy and in some endocrine pathologies. The hormone beta-hCG appears in the body only during pregnancy.
