is it possible to be pregnant with negative blood test?
16586
False negative results (test is negative, but you are actually pregnant) usually occur if the blood pregnancy test was performed too early (a rule of thumb is that it takes at least 7 days after conception for the test to show a positive result).

If the test result is negative, you may not be pregnant. However, negative results are less reliable. For example, if you do a pregnancy test too early, you could be pregnant, but there may not be enough HCG in your body to give a positive test result.

Negative test results If the test result is negative, you may not be pregnant. However, negative results are less reliable. For example, if you do a pregnancy test too early, you could be pregnant, but there may not be enough HCG in your body to give a positive test result.

False negative pregnancy test – how common is it? Yes, wrong pregnancy test results can and do happen. In fact false negatives – where the pregnancy test says you're not pregnant but you actually are – are more common than false positives. However, it's also important to say that this shouldn't give you false hope.

While false negatives are very common, a false positive – where a pregnancy test tells you you're pregnant when you aren't – is extremely rare. That's because there are very few circumstances when your body would produce hCG without being pregnant.

False negative pregnancy tests do occur. In fact, it is possible to have a negative result on a pregnancy test and actually be pregnant.

A negative result can mean that you are not pregnant, you took the test too early, or you took the test wrong. Pregnancy tests vary in their sensitivity (how soon they can detect the hormone hCG), and you may not have given your body enough time to produce enough hCG hormones that will show up on the test.

If your test appears negative but you still suspect you might be pregnant, then you should make an appointment with your GP as soon as possible for another test. False negatives may occur from time to time, but a positive pregnancy test is almost certainly correct.

These tests are almost 99 percent accurate . In most cases, a negative result means that you aren't pregnant.

If you are testing before the date of your expected period, you may be pregnant but your hCG levels are too low for the test to detect. A test may show positive if you have a chemical pregnancy (early pregnancy loss), an ectopic pregnancy, or a molar pregnancy, but this is not a false positive.

If you take a pregnancy test at night and get a positive result, then you are most likely pregnant. However, if the result is negative, it's possible you might not be pregnant. But you may have also just not had high enough levels of hCG in your urine to be detectable.

A negative pregnancy test does not absolutely rule out pregnancy or ectopic pregnancy; it may simply be too early to detect hCG in the mother's urine or blood. A doctor may also order one or more quantitative hCG tests to help diagnose (or rule out) an ectopic pregnancy.

A very rare cause of a false negative is if the hCG hormone in your body doesn't react with the anti-hCG chemicals in the pregnancy test. If this is the problem, you may need to wait a few more days before you can get a positive result. Or, you may need to have a blood test.

Can a pregnancy test come up negative if I didn't pee enough? A false negative on a home pregnancy test is possible, but extremely unlikely. As long as your urine got on the test's absorbent strip, it should be accurate. You can always take another test if you're worried you might have missed.

Getting a false-negative pregnancy test because of the hook effect is rare. False-negative test results can happen for many reasons. One older study that tested 27 different kinds of at-home pregnancy tests found that they gave false negatives almost 48 percent of the time.

Urine HCG tests often return false-negative results, particularly very early in pregnancy. This can be stressful and demoralizing to people struggling to become pregnant. Blood tests are typically more accurate, though even these may fail to pick up low levels of HCG in early pregnancy.

It's possible to get a negative result from a home pregnancy test when you're actually pregnant. This is known as a false-negative.
