Can you get negative urine pregnancy test results when you are pregnant?

Yes, you can get a negative urine pregnancy test result during the early stages of pregnancy, the home tests are not 100% accurate. To test for pregnancy, the urine tests determine the amount of hCG (human chorionic gonadotropin), the hormone of pregnancy, that is in your urine. But they are not very sensitive tests. If there is enough hCG that the test can work to detect it, then the result is a positive test (you are pregnant). In very early pregnancy, until the level of hCG rises high enough for the test to react and give a positive result, you could be pregnant but get a negative test.

It takes about 5-10 days for the fertilized egg to reach the uterine lining. Once it gets there, it implants and starts producing the pregnancy hormone. It can take a couple of days to show up on even more sensitive tests. Therefore, you could have conceived, but not implanted the ovum yet, which still gives a negative test even though could actually be pregnant.

Try taking the test in the morning. That is usually when your urine is most concentrated, making detection of the hCG easier. Wait another week and then recheck. If it still comes up negative, and you still think you might be pregnant, go to your doctor for more sensitive testing or continue to periodically test at home. If you get a subsequent positive test it is usually a good idea to follow with a second test to be sure you didn't have a false positive.

Some medications can give you a false negative, and, as mentioned above, the timing of the test can affect the results. If you did not follow directions properly (for example, if you let the test sit for too long the results may read negative after a while, or if you drink a lot of fluids before taking the test it can dilute your urine and give inaccurate results). It is important to read the results within the amount of time given on the instructions of that particular brand of pregnancy test.

To ensure the best results: Take the test in the morning, if possible, because your hCG (pregnancy hormone) levels are at it's highest, don't drink a lot of fluids before taking the test because it will dilute your urine and can affect the results Take the test no more than 1 day before expected period. Although some tests say that you can see results up to 5 days before your missed period, the percentage of accuracy is very low. Urinate for as long as possible on the foam-like strip. Check the results during the exact window of time suggested by the instructions of the pregnancy test.

A negative test could also be the result of a phantom pregnancy. A phantom pregnancy is where you basically fool your mind and body into thinking it is pregnant. You will still experience pregnancy symptoms but you are not actually pregnant; it is all psychological. Some women have even been able to lactate during a phantom pregnancy. The psychological causes of a phantom pregnancy are usually either paranoia of being pregnant or having an extreme desire to become pregnant.

There are alternative pregnancy tests that can be used in addition to using a home urine pregnancy test. You can go to your OB-GYN to get a proper examination and pregnancy test. They can order a blood test to be done at a lab, or perform one themselves in some cases. A pregnancy blood test can only be performed when ordered by your physician.

There are two types of blood tests to measure the level of hCG: Qualitative and Quantitative beta hcg blood test. The Qualitative blood test is not 100% accurate during the early stages of pregnancy, so it is best to have this test performed after 5 weeks into pregnancy for a more conclusive result. The Quantitative beta hcg pregnancy test is 100% accurate and can be performed as early as 5 days after intercourse. The results will usually take 3 days to come back from the lab and are very accurate and are the best way of determining if you have conceived.

Is a blood test for pregnancy more accurate than a urine test?

  • No Not always a blood test is more accurate, but not necessarily more sensitive. A lot depends on the lab. A quantitative blood test, usually called a beta hCG test, measures the exact units of hCG in the blood. That means it will detect even the most minimal level. There is another type of blood test sometimes called a qualitative hCG. This is a test that simply gives a yes or no answer to whether you are pregnant. Just like urine tests, labs vary as to what is considered a positive pregnancy test. Common cutoffs for positive are 5, 10, and 25 units. A level under 5 is considered negative. A test that is only triggered at 25 units of hCG is not any more sensitive than several of the urine HPTs.
  • Yes, urine tests test for hCG levels in women and A LOT of women have low hCG levels so the tests come out negative even though they are positive.

Is it possible to get a false positive when you take a pregnancy test at a clinic or hospital?

Yes, both false positives and negatives can happen at reliable clinics. Sometimes the reagents used for the test may be old, improperly stored or handled, causing the problem. On the other hand, home pregnancy tests are notoriously inaccurate.

Anything is possible; however, they're usually always right. Sometimes home tests may not be able to detect the pregnancy hormone. If you are pregnant, congratulations, and be very happy!

Would a yeast infection or the medication taken for it cause a false negative on a home pregnancy test?

Nope. Absolutely not. A home pregnancy test is checking for HCG -- the pregnancy hormone -- and neither yeast infections nor their treatment will mask the presence of HCG in someone's body.

How much water does it take to dilute your urine for a false negative on a pregnancy test?

Drink water until your urine is completly clear. I suggest testing this a few times. When it says negative, you have consumed enough. Not gong to ask why you needed to know...

How soon is a home pregnancy test accurate?

A pregnancy test can be positive before you even have missed a period. Many tests can provide positive results within 10 days after you become pregnant, however it is usually best to wait until you've missed a period because the HCG hormone (the hormone found in early pregnancy)will be stronger which in that case will give you definite results.

Can PCOS affect pregnancy test results?

My husband and I have been trying to conceive for 6 months. I have pcos, although its semi-mild. Since I've started keeping track of my periods, they've all been on time, down to the actual day. Untill now. I'm ten days late. And I had these awkward pelvic pains one day after we made love. I've taken 5 dollar store tests (trying not to spend alot of money on what could be just a scare!) they are all negative. But today, I noticed my shirt was wet, and looked down and there was a spot on my shirt from where my nipple was leaking. Theres no other explanation. I'm a perfectly healthy young woman!...why else would it do that, any suggestions here?

How could you get a false pregnancy?

A chemical pregnancy is a flase pregnancy in a way as there is no fetus there its just your body thinking its pregnancy and actually doing everything pregnant bodies do. Its very strange. But the only way to get a false positive pregnancy test is if your taking medication containing HCG. On rare occasions you can encounter a false positive due to improper testing, expired pregnancy tests, rare medical conditions such as certain types of cancer, evaporation lines, a recent pregnancy or a chemical pregnancy.A chemical pregnancy is a very early miscarriage. It usually occurs from the time the women takes a pregnancy test (that shows positive and her period.) and before a heart beat develops. (http://www.babyhopes.com/articles/chemical-pregnancy.html) .

Can a pregnancy test show positive if only one week pregnant?

No. If you are one week pregnant, technically you will not have missed your period yet. Pregnancy is counted from the first day of your last period. So during week one, you are on your period.

The pregnancy will usually be detectable around week 3. That is when the egg meets the sperm and implantation occurs. Once the ovum (egg/sperm) has implanted, your body will start creating the hormone HCG (that's what the pregnancy tests are looking for).

How accurate are home pregnancy tests?

Home pregnancy tests are quite accurate. If anything, they give false negatives because it might not have picked up enough of the pregnancy hormone but positives are usually accurate. If you want to be absolutely sure, take another test and if that one too says you are pregnant, count on it.

most are 99%

Is a home pregnancy test more accurate than a blood test from a doctor?

Home pregnancy test are notoriously inaccurate. Go to your doctor for a serum hcg test.

Over the counter urine pregnancy tests are actually quite accurate. They are not as accurate as the blood test that physicians can order, but newer urine tests can detect HCG in the urine as early as 8-10 days after conception - usually before the 1st missed period.

See the link below for more information.

_____________________________________________________________________

home pregnancy tests claim to be around 99% accurate after a missed period. however, blood tests done at your doctor's office are able to detect levels of HCG much earlier. blood tests are considered around 100% accurate, where as home pregnancy tests are less due to possible errors in timing or errors in performing the test.

The answer preceding this one is accurate in that the blood test may be able to tell you if you are pregnant earlier - we can tell you within 3-5 days if you are pregnant. However, the actual utility of the increase in accuracy is questionable. Most people will not even suspect they are pregnant until they miss a period, by which time an over the counter urine test (which cost about 10 dollars) is just as accurate as a urine or blood test done in a doctor's office (and will cost you over 100 dollars, and possibly up to 500 dollars or more if you go to the Emergency department).

Bottom line: use a urine pregnancy test at home if you have missed your period and think you may be pregnant. If you are pregnant, see your OB/Gyn or Primary care physician for follow up. A blood test is only useful if you are having problems with your pregnancy to help us work out what may be going on.

Why would you have spotted brown two days ago but have a negative pregnancy test?

It may be too early for you to detect the HCG hormone. It all depends on how late your period is... it is quite common for younger women to miss a period one month and the next be right on schedule.. there are a lot of factors.. Ie... Stress, Age, Diet... sometimes if you think you are pregnant your body "thinks" it is as well and will "act" the part.. try to relax and wait and see.. Good Luck
