A test may show a small streak where the positive line should be. This is called an evaporation line. An evaporation line does not indicate pregnancy.
If this type of streak appears, it usually means that a person has read the results too late or has otherwise misused the test. For most women, getting an accurate result merely involves taking another test. Some women take pregnancy tests too early to receive accurate positive results. It may be a good idea to wait for a few days before taking another test. An evaporation line is a slight streak that appears where the positive line on a pregnancy test should be. Evaporation lines are colorless streaks, not faint lines.
They typically appear if a person waits for longer than the suggested time to read the test result. An evaporation line can also appear if the test gets wet. An evaporation line does not indicate that a woman is pregnant.
These lines often occur when a person has checked the result too late or taken the test incorrectly. Evaporation lines only appear on tests that show negative results.
A positive test would change color in the same spot, blotting out the evaporation line. If a person sees an evaporation line, it means that the test is negative, or it was taken too early in the pregnancy to show a positive result. Pregnancy begins when a fertilized egg implants in the lining of the uterus. The body then starts to produce a hormone called human chorionic gonadotropin hCG.
At the end of the first trimester, hCG levels fall. Home pregnancy tests work by detecting hCG levels during the first trimester of pregnancy. Tests that can detect smaller concentrations of hCG in the urine are more likely to show positive results earlier.
The levels of hCG are very low in the days immediately before and after the first missed period. Also, these levels can vary from woman to woman in early pregnancy. Some naturally have lower levels than others. The compounds in home pregnancy tests interact with hCG, and a positive result will often look like a line, a dot, or a plus sign.Enjoying motherhood is a desire that most women look forward to the experience and cherish forever during their lifetime.
When a married woman misses her period, the first thought that crosses her mind is, am I pregnant? Home pregnancy testas it is commonly known, is a very good way to resolve the suspense. You can conduct this test in the comfort of your room, at home itself. Follow the instructions in the manual of the kit carefully for accurate results.
In particular, be careful of false positive results, known as dye run pregnancy test positive, which can mislead you. Some women may experience irregular periods so know when to take a pregnancy test for irregular periods. The test line on the kit is the most important mark to display the results.
Depending upon the placement of the test line, you can conclude if the test result is positive or negative. However, in a few cases, a smudged line appears in the testing window, and this is the false line. This can mislead you as there are high chances of mistaking it as the test line.
Such smudged lines are called Dye run on a pregnancy test. A blue colored smudge is known as a blue dye run on a pregnancy test.
Similarly, a pink colored deformed line is called a pink dye run on a pregnancy test. Always remember that a true test line will never be smudged. It will only appear as a solid line.
When the dye cannot run smoothly on the test kit strip, it gets accumulated in an area, resulting in a smudged line. You cannot consider it as a reliable test if a dye run on pregnancy test smear is formed.
In this case, you must take another test to obtain an accurate result. Dye runs happen when the dye did not get enough time to settle down for the test to complete properly. Dye gets over saturated and does not settle completely.
A common mistake is, reading the test past the given timeframe and therefore interpreting results incorrectly.Using at-home pregnancy tests is one exceptional way to confirm if you are pregnant or not. However, women have a number of concerns about these pregnancy tests. One of the most typical problems they deal with is concerning the evaporation line on pregnancy test.
Are you knowledgeable about this line on a pregnancy test? What does this mean? Keep reading to get more information about it. Pregnancy tests show evaporation lines due to evaporating urine in the pregnancy test window. There will be a very faint line on a home pregnancy test when the urine on it begins to dry up and vanish.
This faint, colorless line can appear on any at-home pregnancy test. In many cases, the evaporation line even highlights the antibody strip and makes women to think that they are pregnant. It is also possible for the second line to look like an indentation.
It is necessary that you do not consider these results positive. This usually takes place when you wait too long to read your test results. There is a specific test window to think about. If you ignore it, you will get inaccurate results due to an evaporation line. An evaporation line looks like a favorable pregnancy test result, it is, therefore, very important to check out directions relating to home pregnancy test before actually taking the test.
You need to know exactly how long you have to wait to check out the results. If you exceed the allotted time, you will have an evaporation line on pregnancy test and get incorrect results. It is likewise crucial to comprehend that not every woman might see evaporation line. That is generally due to special chemical makeup of urine. Due to this chemical makeup of urine that some women see evaporation line immediately after taking the test, while others see it after an hour or two.
An evaporation line can make things confusing due to the fact that it can appear within the rest window exactly where a positive or unfavorable result is. Lots of women conserve the test once they see an unfavorable result and examine it once again an hour later on.
If another line appears hours later, it is an evaporation line and not a pregnancy indicator. While it depends upon the type of test you are using, the response time is normally 5 minutes for many tests. It is generally possible to interpret a negative result within minutes. In case you do not see a positive result within the response time, you ought to not keep it to check it once again later. This will just leave you confused since a second line may appear, which is absolutely nothing however an evaporation line.
Remember that getting negative result does not constantly indicate you are not pregnant. Often, you test too early when your hCG levels are a little too low to show on the strip. It is, nevertheless, essential to discard the test if you see an evaporation line on pregnancy test.
A faint line suggests a positive pregnancy if it appeared throughout the response time. If you see a faint line after minutes of taking the test according the test instructionthen it is an evaporation line and IS NOT an indication of pregnancy.
Instructions on many pregnancy tests will tell you to read the results in a particular amount of time, generally from a number of minutes up until 10 minutes later.We strive to provide you with a high quality community experience.

They were definitely positive just not getting darker like I experienced with my last pregnancy. Probably worried for nothing. The last test is 16DPO. This was my test 9DPO, last year with my son.Pregnancy test retake.
Strong, dark lines super early on so I was worried this go round. Im not ready for the crazy dreams to start up. I had them so bad with my last pregnancy I was scared to sleep sometimes! I am almost 7 weeks. About a week after my first positive.

Is this a dye run or faulty test? I haven't had this happen before so it's new to me doesn't quite look like a positive. Not sure when or if I ovulated as I'm still breastfeeding but I've been feeling really crumby but I've also come down with what may or may not be a flu.
Add a comment. That's weird!! I would test again :.
It showed up almost immediately but the line looks off to me idk. If I ovulated when I think I did I would only be 10dpo so maybe I'll wait a few more days and test again.
I'm new to this whole thing so I'm not sure. I know when I took one of thoses tests the dye ran stright across not stopping.
I think it maybe a positive!!! I would test again tomorrow :. I have seen dye runs that have turned out to be both a bfn or a bfp. I can't wait to see your next test! When is best to test again. I'm nervous but impatient lol. Well that was very dark, so I would be testing with a 4hr hold. Keep us updated!
What to do about an evaporation line on a pregnancy test
Anxious to see resultshope you get your bfp. Just an update. Life got super busy with back to work two kids and my sons first birthday party! I tested again and it was most definitely positive! Went to the walkin for a flu like cold and for blood drawn too and they sent in a request for a dating ultrasound.
But I started bleeding unfortunately I'm upset about it but I'm okay with the whole situation. It will happen again and I believe everything happens for a reason. I'm just spending time giving extra love and snuggles to my littles now.

She loves researching and sharing information on various health topics. It can be confusing when a woman sees two lines on her pregnancy test—one dark and another very faint. If the line appears within five minutes of testing, then a faint line indicates a positive pregnancy. However, a faint line could also be an evaporation line, which, according to Dr. Peter Rizk, MD, "is caused by evaporation of the urine in the result window of a pregnancy test.
It develops after the recommended reaction time frame approx. This may appear on any test regardless of brand. Unlike a faint positive line, which can be a light blue or light pink depending on the brand of the testan evaporation line is nearly colorless. Rizk says that "manufacturers recommend that you should not read tests after a designated time period, as most test brands have the possibility of developing evaporation lines.
An evaporation line appears when a woman waits too long and reads the result after the recommended reaction time period usually five minutes after testing.
This is why it's important to read the results right way. Some women keep the test strip after seeing a negative result and then check on it again after the recommend time and assume they're pregnant when they see a faint line.
If the test turns out negative within 5 minutes of testing, then it is negative. Waiting a few more minutes will not make it a positive result! Evaporation lines do not always appear for every test. This is because urine has very unique characteristics and composition among different individuals. Some women may see an evaporation line after five minutes while for others, this line may appear in an hour or so. An evaporation line does not indicate pregnancy and is merely a result of evaporation.
Do not make the mistake of considering this a faint positive line.
A faint line means a positive pregnancy if it appeared during the reaction time. If you see a faint line after 5 minutes of taking the test, then it is an evaporation line and IS NOT an indication of pregnancy. If you see a faint line within the reaction time period, it is not an evaporation line. No matter how faint it is, this line is considered a positive and is an indication that you took the test too early—most likely right after implantation when hCG levels are still low—or your urine was diluted.
An evaporation line appears after the allotted reaction time and is virtually colorless. Evaporation lines on pregnancy tests are generally colorless, but not always. There are some evaporation lines that do have color—either a light blue or light pink. The color, however, is very faint and not as dark as the color of the control line. The evaporation line can also sometimes appear greyish. On blue dye tests, evaporation lines are very faint.
Evaporation Line on a Pregnancy Test
This type of pregnancy test kit has two windows. The elongated window will show the control line, indicating that the test kit is working correctly. Right beside this is another round window where the test line will show up. Negative Result: A single horizontal line appears for a negative pregnancy test. The horizontal line is always dark blue and solid.
Positive Result: If positive for pregnancy, there will be one horizontal line intersected with one vertical line, forming a plus sign. The evaporation line typically shows up as a very faint, thin and almost colorless vertical line.
If you test early and have low levels of hCG, the vertical line may be faint. Again, if you read it after the recommended reaction time, the vertical line is most likely an evaporation line. A test line should typically appear at the center of the test window.Most people think pregnancy tests are either positive BABY! Me, I'm a pregnancy test hobbyist.
Some ladies dabble in sewing or cocaine, but I'm big on the sport of taking pregnancy tests of all brands, at all times, and peering at the results with the resolve of a seer. It's like reading tea leaves. This hobby is half dye on a pee stick, half esotericism. Sometimes you take a pregnancy test and it is totally blank. From start to finish, there's nary a stroke of dye or speck of dust in the results window. Completely blank tests are reassuring or heartbreaking depending on your life situation, but they are boring.
I threw one of these in the trash the other day and that's really saying something because I like to think of a pregnancy test result window as an evolving story that lapses over several days. A test can be blank at first, then develop exciting lines that can be read in a number of hopeful or terrifying ways. To anyone sane reading this, officially a pregnancy test result should only be read in the manufacturer-suggested time frame.
I feel required to say that for the teens out there who may be reading. I appreciate seeing absolutely zilch on a pregnancy test sometimes because it really frees up my day.
I will stare at an ambiguous test for hours. It's like TV to me to look at a pregnancy test. I literally got bored the other day and thought, "I'll pee on a stick while the kids play" that is how fun I think it is. A slightly faint line in the results window that is so obscure, it is impossible to tell the color. Officially a pink line or blue, depending on the brand means "pregnant" and a gray line means, "this is where a pink or blue line would go if you were pregnant but there's nothing definitive just yet.
It is a common practice to photograph these results and exaggerate their properties in Photoshop, then invite friends to get in on the game.
It's a regular crowd pleaser. Even though I do not want more children at the moment and maybe never, I find myself rooting for this line anyway.
I could have just given birth two weeks ago and be up to my eyeballs in screaming kids with my sights set on a vacation in six months and I will still subconsciously root for a pink line on a pregnancy test. Note: This does not equate with a desire for more children. I liken it to rooting for a horse at a race. Just because you want it to win doesn't mean you want to take the horse home with you and breast feed it for 12 months.
In fact I unexpectedly thought I saw a pink line not too long ago and right after high-fiving it, I cried and admonished my life choices. Whew, that was a close one. Evaporation lines! This is a result in the test window that is blank during the manufacture-alloted time frame and then magically shows up an hour later. These are tricky and in my experience, a much bigger indicator of actual pregnancy.
That's where nerves come in. Officially, these are supposed to be meaningless but the two times I have actually been and remained pregnant long enough to carry a baby to term, I have gotten these elusive evaporation lines first. Let's call these "maybe sticks". Disappearing positives during the allotted time. This never happens to me, but I know it happens to other people.
