The pregnancy tests you get at the drugstore work 99 out of 100 times. They’re just as accurate as a urine pregnancy test that you’d get at a doctor’s office. Pregnancy tests work by checking your urine (pee) for a hormone called human chorionic gonadotropin (HCG
). Your body only makes this hormone if you’re pregnant.
Is one pregnancy test accurate enough?
Many home pregnancy tests typically maintain a 99% accuracy rate or better. The problem lies in the fact that these tests also imply that this accuracy could be expected if you take the test as early as the day of a missed period, but that’s not what they’re testing for in the laboratory to get their 99% accuracy rate.
How common are false negative pregnancy tests?
Home pregnancy tests are usually accurate, but researchers estimate that up to 5% of tests give a false negative — meaning the test says you aren’t pregnant when you actually are. There are a few reasons why you might get a false negative. You might be taking the test too early or after drinking too much water.
Can a first positive pregnancy test be wrong?
Could a positive result be wrong? Although rare, it’s possible to get a positive result from a home pregnancy test when you’re not actually pregnant. This is known as a false-positive.
Do pregnancy tests only work once?
And while they do pretty well at what they’re supposed to do — detect the pregnancy hormone human chorionic gonadotropin (hCG) — to get accurate results, you need to follow package instructions as written. So no, you can’t reuse a pregnancy test.
Can you be pregnant after 2 negative tests?
Is it possible to be pregnant and get a negative pregnancy test result? Yes, it is possible. Getting a negative result doesn’t mean you’re not pregnant, it may just mean your hCG levels are not high enough for the test to detect the hormone in your urine.
What is the Colour of urine in early pregnancy?
Normally, the color of urine can be light yellow or yellow to transparent. But for a pregnant woman, this change is more prominent and noticeable. The urine color can change from light yellow to dark yellow. It can go to an orange-yellow shade too.
How many tests should I take to confirm pregnancy?
It’s a common scene in television shows and movies: A woman takes a pregnancy test, sees the result and then, in excitement or disbelief, takes two more. In reality, taking a second test immediately following the first is often unnecessary.
Why do I feel pregnant but the test is negative?
If you feel pregnant but had a negative test result, you may have experienced a very early miscarriage (also known as a chemical pregnancy). This occurs when there is a problem with the fertilized egg, most commonly a chromosomal disorder that makes the pregnancy non-viable.
Can too much pee on a pregnancy test make it negative?
Excess fluids can impact the accuracy of the test results, so if your urine is diluted or pale yellow, hold off on taking a test. Diluted urine tends to also have diluted hCG levels which can skew the test results. Take a test when you naturally need to pee.
How soon will a pregnancy test read positive?
In many cases, you might get a positive from an at-home test as early as 10 days after conception. For a more accurate result, wait until after you’ve missed your period to take a test. Remember, if you take a test too soon it could be negative even if you are pregnant.
When is it best to take a pregnancy test?
You can take a pregnancy test anytime after your period is late — that’s when they work the best. It’s a good idea to take a pregnancy test as soon as possible if you miss your period or think you might be pregnant.
How common are false-positive pregnancy tests?
A false-positive test result only happens less than 1% of the time, but when it does, it can make the following days or weeks confusing before you realize you’re not actually pregnant.
