Reg dual marker
Hi,
I’m 12w3d pregnant. I have subchorionic hemorrhage of size 58×25×15mm. I received a single 5,000 IU hCG injection on 4 Sept, ~6 days before my dual-marker blood test (10 Sept). Results: free β-hCG 27.02 ng/mL (0.778 MoM) and PAPP-A 1.6 mIU/mL (0.458 MoM); NT was 1.5 mm, NS 2.6 MM, and combined screening was low risk (T21 <1:10,000; T18/13 1:16,655).
Could the hCG injection have affected my free β-hCG/MoM and the combined risk calculation? Is my PAPP MoM concerning? I have attached my reports also.

Your report already shows a screen negative, low risk result for both Trisomy 21 and 18/13. The numbers you're asking about aren't flagged as concerning on their own.
Next Steps
The hCG injection close to your blood test can genuinely affect free beta-hCG and MoM values, so please discuss its timing with your treating obstetrician.
Health Tips
A screening result doesn't rule out every condition, so please continue with your scheduled anomaly scan and follow-ups.
