My blood test result is almost same as you too, v high hcg and v low papp. I'm so worried and anxiously waiting for my harmony results. Did Dr say anything about why the blood results are like this? Mine didn't say much, and I regret not asking more cus I was in shock when I saw the ratio for DS is super high :( my 1st preg was smooth, so didn't expect this kind of results as well :(
i went for amnio due to high risk. baby turned out fine. see if you want to consider for a peace of mind
