Clinical Information (ข้อมูลทางคลินิก):
Non-Invasive Prenatal Testing (NIPT) is a non-invasive test for pregnant women which estimates the risk of a fetus having chromosomal abnormalities. The non-invasive prenatal testing (NIPT) is an advanced screening test using next - generation sequencing technology that is carried out on a small maternal blood sample. During pregnancy, the placenta leaks cell-free DNA (deoxyribonucleic acid) which circulates in the maternal bloodstream. As a result, a maternal blood sample contains a mixture of fetal-placental and maternal circulating cell-free DNA. The non-invasive prenatal testing (NIPT) directly measures the amount of this cell-free DNA and can detect chromosomal abnormalities.

Reference Value (ค่าอ้างอิง):
Low risk
 
Interpretation (การแปลผล):
Low risk: It is very unlikely your pregnancy is affected by chromosomal abnormalities such as trisomy 13, 18 or 21.
High risk: Your pregnancy is at increased risk for chromosomal abnormalities trisomy 13, 18 or 21 and the result should be confirmed by a follow-up invasive procedure such as amniocentesis.
