How possible to get false negative?

Question

Is it possible to get false negative with blood test, is there something called early testing using blood test?

Answer 1

False negatives are possible, but false positives are highly unlikely.  You should really wait until a week after your missed period to be certain.  

Answer 2

it is very unlikely to get a false negative with a blood test it usually is more accurate so if it said negative that's most likely what it is but you never know anything can happen only God knows if you are so pray and ask him to bless you with your baby

Answer 3

A blood est is 100% accurate, provided that your egg has implanted and started producing HCG already, but a blood test just days after ovulation would show something...Good luck to you...
