Examining the condition of the embryo, the doctor looks not only at the results of ultrasound (screening of the 1st trimester). The norms in it are as important as in the analysis of blood. Such an analysis, in addition to ultrasound examination, is carried out to determine at what level specific proteins (placental) are located. The first screening is done in the form of a double test - to identify the level of 2 protein species:- "PAPP-A" - the so-called pregnancy-related plasma protein A.
- "HCG" - the free beta subunit of human chorionic gonadotropin.
