Your MoM values of 1.71 for fb-hCG and 1.67 for PAPP-A aren't read on their own. They combine with your NT scan and age into one overall risk score for Down syndrome and related chromosomal conditions. Your report lists each of those risk categories as below the lab's cut off.
Next Steps
Your scan dates this pregnancy at about 12 weeks 3 to 4 days by CRL, so the next check is usually the anomaly scan around 18 to 20 weeks. Please discuss this with your obstetrician at your next visit, so the full report is read alongside the rest of your pregnancy details.
Health Tips
If any future scan or test shows something different, further testing may be suggested, so keep attending your scheduled visits.
