Today, Alkor Bio has a full range of products that allow you to most reliably form a risk group for developing fetal anomalies and narrow the circle of pregnant women who need invasive diagnostics. Alkor Bio offers kits for the determination of biochemical markers of the first trimester of pregnancy: PAPP-A and St. β-hCG and kits for screening the second trimester: AFP and hCG. It has been proven that the effectiveness of prenatal screening for Down's syndrome increases to 95% if biochemical and ultrasound screening is carried out already in the first trimester: PAPP-A + free β-hCG + TVP (collar space thickness). At the same time, the risk of OST can be determined only in the second trimester. Therefore, it is preferable to carry out prenatal screening in the first and second trimesters. Experts in the field of prenatal screening recommend using automated software systems to calculate the risks of chromosomal abnormalities and fetal developmental disorders. Alkor Bio offers a software package for prenatal screening of Down's syndrome "Isida ™". The Isida ™ software package calculates the risks of Down's syndrome, Edwards syndrome, DZST, as well as the risk of fetal growth retardation, taking into account the correlation between all markers (biochemical and ultrasound), and the woman's history, which provides high accuracy in calculating risks, reduces the number of false positive results.
