How accurate are Blood Pregnancy Tests?

Anyone ever got a negative blood pregnancy test and found out later that you really were pregnant? Thanks to all answers!!!

1. I've had over 11 pregnacy blood tests. I would say they are 99.9% correct.
2. the only reason it would be negative was if it was too soon to take it but blood test are like 99.99%
3. HCG levels need to be 10 or above to be considered pregnant with a blood test so if the test is negative that means HCG level was below 10 so you aren't pregnant however that doesn't mean that you didn't just get pregnant so a later test may be positive as the blood test usually works around 12 dpo (sometimes more like 14 dpo). At 14dpo my HCG level was 42 with my second son so I should have tested positive a couple days before but at 10 dpo I might have tested negative. Does that make sense lol
4. blood tests are very accurate rarely do they cum baq negative..if it does nd yu highlt sespect you are pregnant then you probably took the test to early nd shud try baq in like a week
