how accurate are preg tests?

Question

a friend of mine just asked me this:

she took a pregnancy test after she felt that she might be preg but it came up negative...here we are one month later no period is she pregnant?

Answer 1

read the box, itll tell you how accurate the test is. really, theyre not very accurate until about 4 days before you are supposed to get your period. anyway, read the box.
if shes supposed to get her period, and she hasnt, no matter when the test says she should go to the gynocologist. it could be something simple like a change in her hormones due to stress or maybe shes been exercising more then usual. that can affect a woman's period. however, it could be that she actually is pregnant, or there could be something else wrong that the gynocologist can test for. either way, its a good thing to go and get checked out.

Answer 2

I had an ectopic pregnancy 2 years ago. I thought I was pregnant, but took 2 pregnancy tests that came back negative. The day after I took the 2nd one I was in the hospital and 10 weeks pregnant with an ectopic pregnancy. Apparently, when you have an ectopic pregnancy, the tests don't work most of the time. If she has any pregnancy symptoms, she needs to go to the doctor and get a blood test.

Answer 3

My woman can have very very late periods. Each woman is different. The test are accurate but might take some time to get the results. Blood test are the best way to really find out.

Anything can alter the period (Stress, Depression, Sickness, Medications). Some women are like clockwork, and some can actually miss allot.

Answer 4

i was 3 months preg until a home preg test came back +
blood test can tell you if your pregnant as low as 2 days. plan parenthood does them for like $20 i think... not really sure. or your doctors office.
try that.
some females dont get the pregancy hormones till later, and thats what home tests pick up.

Answer 5

If it were positive, then it's very accurate. Negative isn't quite as accurate (in other words, a false negative occurs once in a while). If she skips another period, it's time to go to the doctor and find out what's going on.

Answer 6

nicely, how some time past grew to become into it which you had intercourse? relies upon on that i assume. I mean, in case you had intercourse on Tuesday and had the attempt finished one Wednesday, then specific...this is amazingly attainable that this attempt gave you an erroneous examining. you may desire to attend a minimum of a million week or a million formerly you circulate off and take a attempt like this. for the main section, although, those tests are tremendously precise.

Answer 7

I called the number on the back of the box once. The lady said you can get a false neg, but not a false pos. Maybe she should make an appt. with her dr. for a blood test.

Answer 8

She will need to take a nother test. But it could be possible. But she could be stressed and thats why it hasn't come yet. Retake the test.

Answer 9

Have her take another test to be sure. If it's negative then she should go see her doctor to see what's going on.

Answer 10

take another test
