The non-invasive prenatal genetic test report includes basic information of the examiner, test items, tips, trisomic risk index, reference range, fetal trisomic risk, description of results, and other tips. Common diagnoses: high risk for trisomy 13, high risk for trisomy 18, high risk for trisomy 21, low risk for trisomy 13, low risk for trisomy 18, low risk for trisomy 21, etc. 1. High risk report interpretation: When the test result is high risk, it usually indicates that the fetus may have this screening target disease. On the other hand, a false positive result may occur because the current testing technology cannot yet completely exclude contamination by maternal factors. Therefore, follow-up genetic counseling and other appropriate prenatal diagnosis should be performed at the testing facility in a timely manner, and pregnancy should not be terminated directly based on high-risk results. 2.Low risk report interpretation: the test result is low risk (no obvious abnormalities), which usually indicates that the fetus has a low risk of developing the screening target disease. However, because of the false-negative rate of the current testing technology, the low-risk test result cannot completely exclude the possibility of other abnormalities, such as partial monosomy, partial trisomy, partial tetrasomy and chimeric trisomy of chromosome 21, 18 and 13, as well as mental retardation and malformation caused by other factors. Therefore, the test result cannot be used as the final prenatal diagnosis, and pregnant women should undergo subsequent routine prenatal checkups on time under the advice of the testing institution. 3.Other: If the test report indicates that the test has failed and requires a new blood collection, the pregnant woman should cooperate in time; if abnormal fetal imaging results are found, regardless of whether the test results are high or low risk, professional genetic counseling and subsequent prenatal diagnosis should be conducted; if the test results of some pregnant women cannot be determined or cannot be explained, further genetic counseling should be conducted according to medical advice, and comprehensive ultrasound The results of some pregnant women with indeterminate or uninterpretable test results should undergo further genetic counseling and comprehensive ultrasound evaluation and prenatal diagnosis according to medical advice.
