Hi Ladies --
I got the results of my first trimester screening last week and although the NT was fine and the nasal bone was present, my free beta HCG was "extremely low" (0.3MoM, 1st percentile) and my pappa was low (0.43MoM, 10th percentile). Since I am 37, they calculated my risk assessment of T18 at 1/40. I had the Harmony test done yesterday morning and now I have to wait 9 - 11 more days. Complete agony!
From the reading I've done though, it seems like a low free beta HCG and pappa would more likely indicate potential placenta-related problems and slow growth, low birth weight. Which makes sense to me because in my first pregnancy I had placenta previa (which ultimately went away on its own) and both my children were on the smaller side. My son was born at 5 lb, 13 oz and my daughter at 6 lb, 7 oz.
I'm trying to stay positive but the thought of T18 is killing me. Anyone been in a similar situation? Any thoughts on the low blood work??
Thank you in advance!
Re: Very Low Free Beta HCG & 1/140 Risk of T18
Her blood work was very similar to yours - super high risk for one of the trisomies, and a good ultrasound.
