Can a pregnancy test come back positive even though it should be negative?

Answer 1

It's possible, but highly unlikely.

False negatives are common. False positives are a different story. The circumstances under which a person might get a positive result on a pregnancy test but not be pregnant are:

* the woman has been using certain fertility drugs
* the woman has recently had a miscarriage and the test detects hcg "leftover" from that pregnancy
* certain kinds of cancer, and certain ovarian cysts, cause the body to manufacture hcg (extremely rare)

If you get a positive result, you have to assume it's valid.
If you get a positive result one day and either get a negative result shortly thereafter or get your period shortly thereafter, you experienced a chemical pregnancy (a very early miscarriage) and not a false positive. The tests work by detecting levels of hcg (human chorionic gonadotrophin), a hormone your body starts producing once an embryo implants into the uterine lining. With the very very rare exception noted above, your body is not producing detectable levels of hcg unless you're pregnant.

Answer 2

It is almost impossible to get a false positive. If you just read the box, it says that you can get a false positive only if the test is faulty (which is almost impossible), you have recently miscarried, or you have recently given birth. It is very common to get a false negative, however, because what a pregnancy test does is detect the pregnancy hormone. If you aren't very far along you can get a negative reading because there isn't enough of the hormone in your system. It can't be the other way around though except for the reasons listed above.

Answer 3

Even though pregnancy tests are typically supposed to be accurate, there are no over-the-count pregnancy tests that you would find in a pharmacy that are not 100% accurate. So yes, it is possible that even though the test comes back positive, it could indeed be possible that a woman is not even pregnant and vice versa. I've overheard this from a doctor. The best way you can get the best results to find out if a woman is truly pregnant or not is to go and actually see the doctor.

Answer 4

Yes it is possible for a test to come back positive when you are not really pregnant, but it doesn't happen very often. Most of the time if there is an error in the test it says negative when it should say positive.

Answer 5

Most assessments are now not accurate after 10 minutes. If at 3 minutes the outcomes used to be bad, then its bad. Most tests are accurate when you are per week late so i might say you traditionally aren't pregnant. Wait yet another week and retest. I select the manufacturer answer. Its quite low-cost, costing about $10 for 2 tests and its constantly been correct for me. If the subsequent checks is terrible once more, you may also need to see your ob/gyn to talk about your irregular cycle. Stress is a key aspect in making your interval late.. As is weight attain/loss. So many matters can have an impact on your interval, no longer just pregnancy. Quality of good fortune!

Answer 6

Unless you are on a medication that can cause this, the answer is no. The pregnancy hormone that is detected on a test is not found for any other reason, short of certain kinds of medication.
That being said, a test can pick up a chemical pregnancy -- that is, you are pregnant, but the baby, for natural reasons, is not going to survive. In this case, the preg. hormone is produced, but the baby is miscarried in the first week or two, thereby producing no preg. symptoms and a regular period in about 4 weeks.
Short answer: if it says you are pregnant, you almost certainly, at this moment, are.

Answer 7

Why should it be negative? Do you have a medical issue that you couldn't be pregnant? Or do you just not want to be pregnant? Typically you don' t get a false positive on a pregnancy test. See your doctor for a definite answer.

Answer 8

A pregnancy test tests for the HCG hormone. This hormone is produced from the placenta and begins to be produced as soon as the fertilized egg implants. If there is no placenta, i.e. no pregnancy, the test will not show positive.

Answer 9

You can only get a false negative not a false positive sorry hun you is pregnant. Best advise is get to the docs a have a blood test then you will know one way or the other..

Answer 10

maximum checks at the on the spot are not precise after 10 minutes. If at 3 minutes the outcome replaced into detrimental, then its detrimental. maximum checks are precise once you're a week late so i'd say you possibly at the on the spot are not pregnant. Wait yet another week and retest. I want the style answer. Its extremely low-cost, costing about $10 for 2 checks and its continually been precise for me. If the subsequent checks is detrimental back, you may favor to work out your ob/gyn to communicate your abnormal cycle. pressure is a key element in making your era late.. as is weight benefit/loss. this kind of large number of issues can influence your era, not basically being pregnant. best of success!
