Serological Down syndrome screening is a test to screen for the possibility of fetal Down syndrome. It has no side effects, is simple, economical, non-invasive, and is suitable for popularization.
Detection methodology: In the detection of multiple indicators of serological Down syndrome screening, enzyme immunoassay, time-resolved immunofluorescence method, and chemiluminescence method are generally used. The chemiluminescence method has a high degree of automation, is easy to operate, and has the widest application range.
The detection rate of triple screening is higher than that of double screening, and Tang screening triple testing is commonly used in clinical practice.
Exclusive software:
When calculating the results, it is necessary to have a large number of data from normal pregnant women and pregnant women with Down syndrome as a basis for accurate calculation.
Correction of various factors is very complicated and special software provided by the instrument used must be used
Technical Parameters
Product Uses
Early pregnancy: 7 to 13 weeks after pregnancy;
• Double screening: serum PAPPA (pregnancy-associated protein-A) + HCG or free β-hCG, combined with maternal age and other parameters to calculate the risk of fetal DS.
Second trimester: 14 to 20 weeks after pregnancy;
• Double screening: serum AFP + HCG or free β-hCG, combined with maternal age and other parameters to calculate the risk of fetal DS.
• Triple screening: serum AFP+hCG or free β-hCG)+free estriol, combined with maternal age and other parameters to calculate the risk of fetal DS.
Product Operate Guide
The concentration of AFP, β-hCG and uE3 in the blood of pregnant women is tested, and combined with the age of the pregnant woman, the computer Down syndrome screening software is used to accurately calculate the risk of each pregnant woman carrying a fetus with Down syndrome.
The test results show that the risk is lower than 1/270, which means the risk is relatively low, and the chance of the fetus having Down syndrome is less than 1%.
If the test result shows that the risk is higher than 1/270, it means that the risk of fetal disease is higher, and further amniocentesis or chorionic villus examination should be performed.
FAQ
1. Is joint testing necessary?
Yes. Choose according to the pregnant woman’s pregnancy cycle
2.Does Down syndrome software need to be purchased separately?
Yes
3. Is Tangsie software used in closed systems?
Yes, only applicable to analyzers produced by ZECEN
