I have a friend who works in a lab in a hospital. When I told her I was TTC, she told me that her lab stashes these pregnancy tests that cost $100 a piece (!!), but can tell whether the egg has been fertilized within 2-3 days after fertilization. I explained to her everything I had read about how your body doesnt produce hCG until after implantation and blah blah blah...and she insisted that her tests cannot be bought by the public, are only for laboratory use, and can tell within 72 hours of fertilization.
Now, Ive looked around, and a few sites do concur with what shes saying...that hCG is produced before implantation...But I still dont know what to believe...She sent me 7 tests (ssshhhh...I know, shes a criminal ), and I dont want to waste them, so thusfar Ive been just using them on 10 DPO and have had BFNs every time....which is fair enough, because Ive never been pregnant (except for that very early miscarriage).
The first detection of hCG in the blood depends on when implantation happens. Extremely sensitive tests which are not available in a regular laboratory can detect the hCG even before implantation. But with regular laboratory hCG tests, hCG is usually found in sufficient levels as early as 2-3 days after implantation.

In order to test positive on a home pregnancy test, there must be hCG present in your blood stream. hCG production starts at an early stage of development, just a few days after conception, before implantation in the uterus, but you will not be able to read until after implantation.

hCG is produced by the trophoblast cells of the placenta. hCG production starts at an early stage of development, just a few days after conception, before implantation in the uterus. hCG enters the maternal circulation almost immediately after implantation of the embryo (blastocyst) on about day 21 of the menstrual cycle.
