I was wondering if anybody knows what levels of HCG First Response tests actually pick up? I've seen studies that say 6.5, and I know for a fact that they detect at least 8 as I've had faint positives on the same day as having blood HCG of 8. I even read a post from one woman saying that she got a positive First Response when her blood HCG was 2!! That seems somewhat unlikely, though.
The reason I ask is that I am going through a miscarriage and my HCG is dropping pretty slowly. I'm taking a First Response test every day and still getting faint positives. My blood HCG on Monday was 8, and it's being tested again this coming Monday. I'm very scared that my HCG might have plateaued or gone up
So far: 8 Sept - HCG 150 (GUESSTIMATE BASED ON CLEARBLUE) 13 Sept - MVA - scan confirmed womb clear 16 Sept - HCG 20 (GUESSTIMATE BASED ON CLEARBLUE) 17 Sept - 3cm chunk of tissue comes out which MVA and scan somehow missed! 18 Sept - HCG 19 21 Sept - HCG 19 27 Sept - HCG 11 2 Oct - HCG 8
