Patient's question:
Age: 26 years, Height: 160 CM, Weight: 61 KG, Gestational Age: 16 weeks 6 days (calculated from the last menstrual period)???Last Menstrual Period: 2013-3-15??Actually, this data is incorrect; it should be: 2013-3-25. This incorrect last menstrual period value might affect the test results, or it might not. Why is mine 1/15? Everyone else's is 1 in hundreds?br/>The report results are as follows:Free-hCG B Result: 69.4??MOM: 5.16AFP????????Result: 16.4??MOMDoctor's answer:
Analysis of the condition:1. Down syndrome, also known as trisomy 21, refers to a condition where the patient has an extra chromosome in the 21st pair (while the normal number is one pair). Down syndrome screening is performed by measuring the levels of AFP and HCG in the pregnant woman's serum, combined with the woman's age, weight, and gestational age to calculate the risk value. The critical value is 1/275. A value greater than this indicates high risk, while a value lower than this indicates low risk. The probability of having Down syndrome (DS) in the general population (under 37 years old) is 1/750.
Guidance:
If the screening result is high risk, it is recommended to undergo amniocentesis. However, even if the result is high risk, it does not necessarily mean the child will have Down syndrome. For safety's sake, it is still advisable to undergo DS screening! Children with Down syndrome have severe intellectual disabilities, cannot live independently, and often suffer from complex cardiovascular diseases, requiring long-term care from family members. This can impose significant emotional and financial burdens on the family.
