Blood Drug Testing

Are pregnancy blood tests 100% accurate?

Hi! I went to the doctor on Saturday morning (3 days ago). At that time I was 11 days late on my period. Today, I'm 14 days late. I had slight cramping for three or four days last week, but I haven't had any cramping for the past 2-3 days. There is a chance that I could be pregnant, as I've had intercourse multiple times over the past month. I've been super tired & not feeling very well. I was under the impression that blood tests were 100% accurate, but now I'm not so sure! Can someone please help me with this? Thanks so much :)

1. Blood is 100% accurate. Just because you are late, dont mean your pregnant. I am 2 wks late and am not pregnant.
2. Unless there was a lab screw up,then you aren't pregnant. Blood tests are very accurate and can detect very small amounts of the pregnancy hormone.
3. i would tend to believe that blood tests are 100%, but have you ever seen that show on discovery 'i didnt know i was pregnant?' women on that show have had blood tests done that didnt come out positive when they shouldve... maybe you just had the bloodwork done too early. good luck!
4. No they are not.
