I peed on the test result window; does it affect the result? It happens! As we stated above, the test window isn't waterproof, so it's possible you could get an inaccurate result. Try taking another test (use a cup and dip the test if that's easier!) to ensure you're getting accurate results.
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.
No pregnancy hormone level present 1 red line in the control window (C) means that your pregnancy hormone levels are falling and the products of conception has been passed. The result is invalid (the test has not worked) if no red line appears in the control window (C), even if a line appears in the test window (T).
If there's no hCG, the mobile antibodies just sail on past. Whether the woman is pregnant or not, another line appears on the test in what's known as the control zone. Here, more immobile antibodies bind to the excess mobile antibodies that didn't pick up hCG and continued travelling up the strip.
When taking a pregnancy test, any line in the test indication area is considered a positive pregnancy test, even if it is lighter than the control line. The darker line is usually the control line.
Should I dip my home pregnancy test in urine, or pee on it? Most tests allow you to either place the absorbent tip in your urine stream for (usually) five seconds or dip the tip in a collected urine sample for five to 20 seconds. Accuracy is not dependent on the method as long as you follow the instructions.
HCG is at its highest level in the morning when urine is fresh and not diluted by the liquid you drink during the day. If you test in the afternoon, your urine may not have enough HCG to detect.
Fertility medication or other medicine that contains HCG might affect home pregnancy test results. Most medicines, though, including antibiotics and birth control pills, don't affect the accuracy of home pregnancy tests.
In general, the best time is when you have your first morning pee. However, some pregnancy tests are sensitive enough to detect HCG no matter what time of day you take the test.
If you're using an early detection test, you may need to hold your pee for a few hours before taking the test. This is because hCG levels are highest in your first morning urine, so holding your pee for a few hours can help increase the concentration of hCG in your urine.
Levels of hCG will be strongest with first morning urine — more concentrated urine guarantees a more accurate test. Your test will still be valid if it's the afternoon or you've already had water, but first morning urine will result in a stronger results line. The stronger the line, the more accurate the test results.
You can do a pregnancy test on a sample of urine collected at any time of the day. It doesn't have to be in the morning.
Although you may take a pregnancy test at night, the test may be a false negative since urine tends to be more diluted at night. This is why doctors recommend taking a pregnancy test in the morning, especially in the first couple of weeks of pregnancy.
Place the pregnancy testing stick on a flat, dry surface with the "result window" facing up. The instructions will tell you how many minutes to wait for the results to appear. This can be anywhere from one minute to five minutes, though some home pregnancy tests can take up to 10 minutes to give you an accurate 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.
There's only one way to find out for sure if you're pregnant: take a pregnancy test.
It's possible to get a negative pregnancy test result followed by a positive result, especially if you tested early. This is because hCG levels rise rapidly in the first few days after implantation. It's also possible to get a positive test result followed by a negative result.
If you saw a faint positive result and retested in a few days with a negative result (or you got your period after testing positive), you may have experienced a chemical pregnancy or early miscarriage. A chemical pregnancy means the egg was fertilized but didn't completely implant.
For the most part, pregnancy tests don't get darker as they go along. “These tests are designed to be read usually within 10 minutes of you doing the test,” says Dr. Demosthenes.
Know this: All Clearblue® pregnancy tests are over 99% accurate from the day you expect your period. False positives very rarely occur, and are often due to medical conditions or certain medications. False negatives, while more common, typically occur due to testing too early or drinking too much liquid before testing.
