Did you ever have a false negative result in a pregnancy test?

Question

If yes, when did you take that test?

Answer 1

No, however, I know my girlfriend did. They are a lot more common than positive results. Maybe you did the test too early to detect HcG. If it is early, then I suggest getting a blood test done to see if there is HcG deteced in your blood. It is 100% accurate and you will know your answer sooner.

Good luck and Merry Christmas

Answer 2

False negatives are much more common than a false positive. Pregnancy tests available to the public test for the presence or absence of a pregnancy hormone in the urine. The trick is that you have to test after the blood level of the hormone gets high enough (as in an advancing pregnancy) to spill over into the urine to be picked up by the test. Many times in early pregnancy the blood level is simply not high enough yet to get to the urine, but you could still definitely be pregnant! The over the counter tests are getting more sensitive and able to pick up lower and lower levels all the time. But the Gold Standard is just to go get a blood test. It's always reliable. False positives are rare though, as the test would have to be picking up in error something else other than the hormone it is delveloped for. Not a easy or common feat at all! If a urine pregnancy test was positive for me, I'd be picking out a crib and changing table. If, however, I thought I was pregnant but the urine came back negative, I'd get a blood test before I'd let out my breath!

Answer 3

YES! I took a test 7 days after having sex. I thought I couldn't wait another minute! The test was negative, but I'm certain I'm pregnant and all ready showing some symptoms.
The level of hCG is what determines the results of your test. hCG begins to build up on the day of implantation in the uterus (which is generally believed to happen 7-10 days after sex). On the first day (implantation day!) the level of hCG is very low. But, the good news is-it doubles to triples everyday thereafter....SO...wait at least 10 days after sex and then test. Testing before that time will likely yield a "false negative". Also, test with the first urine of the morning OR only test with urine that has been in your bladder at least 4 hours. Those will have the highest concentrations of hCG. Hope this helps!

Answer 4

yes yes yes I have!

okay, now to clarify. I've had three pregnancies. In all three of them I tested ASAP. With the first two pregnancies, I used the same brand test, generic WalMart brand, and got faint lines on both, but nonetheless, positive results. The third pregnancy, I tried those First Response tests, that are supposed to tell you UP TO 5 days early. I bought two, and they sucked! I took the first one 5 days early, odds of accuracy are lower than the day after your missed period, and it said no. I took on the day before I was due to start, and it said NO!!!! Unable to accept the fact that I was not pregnant, I went and bought a generic WalMart test, and took it the same day as my last First Response test. It was positive before I could finish taking it!

Now here's the kicker. I had twins last time! Twice as many babies, twice as much of the pregnancy hormone in the system! Morale of the story? Generic is just as good, and in my opinion better, than the store bought ones. Why waste your money?

Oh and yeah, it's absolutely possible to get false negatives on urine tests, false positives are much much less likely!

Answer 5

Yes, but it wasn't technically a 'false negative'.

My hCG levels weren't high enough for it to detect yet. So the test itself didn't give me a false answer and it wasn't defective. I just should have waited longer and/or used a more sensitive test.

I got that five days after my period was due. I finally got a positive with a different (more sensitive) brand a few days later.

Answer 6

It has never happened to me, but I'm sure it happens on occasion. You should wait at least 10 days after a missed period to take a pregnancy test. If you are getting them over the counter & it was negative & you believe you are pregnant, go to your local women's health clinic; they will do a preg test & are probably more accurate!

Answer 7

yes it is possible to have false negative. It may be to early for the test to read your HCG level. If you are really anxious to know go to the doctor and have them do a test they are much more accurate.

Answer 8

it quite is too early. First reaction assessments have a sensitivity of 25iu. meaning it could hit upon as low as 25 instruments of hcg, the being pregnant hormone it is produced with the help of the toddler. At 3 days in the previous your predicted era, regardless of in case you're pregnant, it could basically be too early and the toddler (in case you're pregnant) could not be making sufficient hcg yet for it to be detected. not all of us will attempt constructive that early, even while utilising an quite gentle attempt. Wait a pair greater days and attempt lower back.

Answer 9

I had 18 of them and it was a week after my period was late. Then I got a blood test and it was borderline. I finally got a positive about 1 1/2 weeks after my period was supposed to start. I hope this information helps. Good luck

Answer 10

I had 2 false negatives with my son and both were taken after the missed period.
