What does a faint line look like? Each pregnancy test is different, with some brands using a red dye and others, like Clearblue®, a blue dye. For a red dye test, a faint line will look light pink, whereas a blue dye test will produce a light blue line.

While a dark line that shows up quickly is a sign that there’s more virus in your body, even a faint line can be positive (and may turn darker if you test again in the coming days).
How do you tell if it’s a faint line or evaporation line?
How much HCG does a person need for a positive pregnancy test? – Some pregnancy tests promise to detect pregnancy 5 or more days before a missed period. While they often can, the effectiveness of the test depends on the level of hCG in the urine. According to research published in 2014, the average hCG concentration in urine at 9 days after ovulation — around 5 days before a missed period — is 0.93 milli-international units per milliliter (mIU/ml).
- Most early-result pregnancy tests can only detect hCG when it rises to levels of 25 mIU/ml or higher, which happens after ovulation around day 11 By day 14, hCG levels are typically around 137 mIU/ml.
- For some people, however, they can be as low as 45 mIU/ml.
- Because hCG increases so rapidly in the early days of pregnancy, getting the day of ovulation wrong by 1–2 days can affect the result of a pregnancy test.
A person who believes that they are on day 11 can often expect an accurate result, but if they are actually on day 9 after ovulation, the test may not be able to detect pregnancy accurately. False negatives are more common than false positives. If the result is negative, it may be a good idea to take another test in a few days, to give the hCG levels a chance to rise.
Very few medications, including fertility drugs, may cause false positives. Otherwise, a positive result followed by a negative result a few days later could mean a very early pregnancy loss. In early pregnancy, there may be very little hCG in the urine, and the positive line may be faint. But even a faint positive line has color, and this distinguishes it from an evaporation line, which is colorless.
Faint line on a pregnancy test- Are you pregnant? A fertility expert explains
Any coloration in a positive line indicates pregnancy. A mark on a pregnancy test may be an evaporation line if:
More than 10 minutes have passed since taking the test.The mark is faint and colorless, and it resembles a water spot.The mark has no visible dye in it.
If the control line on the test does not change color, this means that the test has failed. A line on a pregnancy test a positive result if:
There is a visible dye in the line, even if the color is faint.The line appears within the period specified on the instructions, which is usually 3–5 minutes.A person has taken an early-result test at least 11 days after ovulation.A person has taken a regular test at least 14 days after ovulation.A person has missed her period.
Evaporation lines are also likely to appear if a person has not followed the instructions on the test’s packaging. To prevent evaporation lines:
Try urinating in a cup before taking the test, then dipping the test in the urine for the duration specified on the box. This technique prevents too much urine from splashing onto the test.Do not use a pregnancy test that has passed its expiration date.Avoid storing pregnancy tests in very hot or cold locations.Check the results within the time frame specified by the test instructions. Evaporation lines and false positives can appear over time.
Urine hCG concentrations are often highest when a person wakes up. Taking a test first thing in the morning can increase the chances of an early positive result. Waiting for the results of a pregnancy test can be agonizing. If the result shows a colored line, even a faint one, then the test is likely positive.
If the results show a faint, colorless line, then this may be an evaporation line. A simple way to help ensure accuracy is to take two tests and carefully follow the test instructions. Anyone who is unsure of the results should give hCG levels time to rise and take another test in a few days. This can reduce the risk of false negatives.
A doctor can provide the most accurate results by testing the blood or the urine.
What does an evaporation line look like?
An evap line is a faint streak that’s so light it may look gray or almost colorless. It’s not as dark or bold as the control or positive result lines.
What if a faint line appears after 30 minutes pregnancy test?
It’s possible. Some home pregnancy tests are sensitive enough to detect tiny amounts of pregnancy hormones in your system, even before you have missed a period. To get a positive result, you need to be making a detectable level of a pregnancy hormone called human chorionic gonadotropin (hCG).
- The more sensitive a pregnancy test is, the earlier it will show a positive result.
- It’ll depend on how much hCG your body is producing too, as every woman’s response to pregnancy is individual.
- If your home test shows only a faint positive, it may not be sensitive enough to give you a clear answer.
- Check the side of the box to find out what your test’s sensitivity is.
For example, a test with a sensitivity of 10mIU/ml (milli-International Units per millilitre) will tell if you’re pregnant sooner than a test with a sensitivity of 25mIU/ml. You may get a faint positive because you’re not as far along with the pregnancy as you expected.
Sperm can live inside your body for up to seven days, waiting for an egg to be released. So depending on when you ovulate, you could get pregnant up to a week after having sex. Alternatively, your fertilised egg may not have implanted in your womb as quickly as expected. Another possible explanation is what’s known as an “evaporation line”.
This is a faint line that can appear as urine evaporates from the test, and it means you’re not pregnant. The instructions that come with the test will tell you how long to wait before checking the results. If the faint line appeared a few minutes after this time, it’s possible that it’s just an evaporation line.
If you get a faint positive, you could try again using a digital pregnancy test. These are easier to interpret than a faint line, as they state whether or not you are pregnant. However, if you’re testing early on, their accuracy still depends on the sensitivity of the test. Alternatively, you could try taking another test in three days’ time.
If you are pregnant, and your body is making the normal amount of hCG, the test should be clearly positive by the time your period is due. These early days while you wait to find out whether or not you are expecting can be an emotional rollercoaster. Unfortunately, it is possible to have a faint positive, only to get a negative when you retest a few days later.
If this happens to you, it may be that you have had a very early miscarriage. Sadly, miscarriages are very common, with a quarter of pregnancies thought to be affected. Learn more about early miscarriage, One of the downsides of having such sensitive pregnancy tests is that, for some women, they may raise false hopes.
When tests were not as highly sensitive to hormonal changes, very early miscarriages would simply go unnoticed. However hard it is, it may be sensible to wait until the day your period is due before testing. That way, you can be more sure of the results.

Can be a positive line be almost invisible?
Sometimes it’s easy to say whether the pregnancy test is positive or not, but sometimes this other line can be very faint. If you see a positive line, even if it’s faint, the simple answer is: Yes, you are almost certainly pregnant.
What are the chances of being pregnant with a faint line?
Most likely, if you see a positive line on your HPT, even if it’s faint, you are almost certainly pregnant. But if you do see a faint positive and you’re still not sure whether or not you are pregnant, try waiting a day or two to take another test to give your body a chance to build up its hCG.
Why is my pregnancy test line getting lighter?
Reasons Why Pregnancy Test Lines Could be Getting Lighter – If you notice your pregnancy test lines are not getting darker, there could be several reasons:
- You could be testing with multiple brands of pregnancy tests. Each brand and style of pregnancy test is unique, and some lines will be darker than others based on the variation in minimal concentration testing, test line dye, and manufacturing. It’s not advised to compare these tests.
- You could be testing at different times of the day. The ideal time to take a pregnancy test is first thing in the morning, when you’ve had an entire night without urinating. This gives you the most concentrated urine sample and the best chance of spotting an early pregnancy with a pregnancy test. If you take a test with your first morning urine and another 2 hours later, it’s likely that the strength of the test line will vary due to the varying concentration of the sample.
- You could be testing at different levels of hydration. Just like an overnight sample is ideal since it’s more concentrated, a pregnancy test line will be darker when the body has not recently had high water intake. If you took a test using a concentrated sample, and another after a lot of water intake, the line could be lighter.
- You could be testing decreasing amounts of hCG. If you are using the same brand of test at the same time of day with the same levels of hydration, it’s possible that the tests are showing a decreasing amount of hCG hormone. There are many reasons for this and, while one is miscarriage, there are other possibilities, as well.
Can evaporation lines have Colour?
What color are evaporation lines on pregnancy tests? – Wait, so do evap lines have color? In the great evaporation line vs faint positive debate, how do you tell which is which? The key difference is that an evaporation line is colorless (which may appear as a faded gray on most tests).
- This is an important distinction because if your test is positive, the line that tells you it’s a positive result will appear in the same spot as the evap line – but will have some color to it.
- BTW, if you need help, there’s a whole Peanut community dedicated to this very topic) So if you’re looking at an evaporation line with blue dye or a pink evaporation line, chances are, you’re looking at a BFP ‒ a big fat positive ! That being said, pregnancy tests that use blue dye can be harder to read, since gray evaporation lines can look blue.
(https://www.peanut-app.io/blog/false-positive-pregnancy-test0 blue dye evap lines are very much a thing. So much so, that most healthcare professionals would recommend a pink dye test over a blue everytime. The key way to tell the difference between an evaporation line vs blue dye positive lines is to see whether the line gets thinner.
Does evaporation line appear everytime?
On a pregnancy test, how do you tell if you’re pregnant? – It’s common to see evaporation lines appear during a pregnancy test, but they don’t always. Make sure you check your results within the reaction time if you’re using a home pregnancy test. Depending on the brand, this is the window of opportunity to get an accurate result.
- Instructions are included with each home pregnancy test.
- Make sure NOT to open a pregnancy test kit and take the test without reading the instructions because they are so easy to use.
- Following the instructions and checking your results before the urine completely evaporates is the best way to avoid mistaking an evaporation line for a positive test line.
Some tests show results within two minutes. Others have a five-minute time limit for checking results. When you read your results after the reaction time, the risk of a false positive is greater. Pregnancy test evaporation lines can be avoided if you follow these tips.
- The reaction time is followed by the appearance of an evaporation line on a,
- It’s difficult to tell if a faint test line is an evaporation line or a positive result if you leave the test sitting for a long period.
- Failure to check your results within the allotted time will necessitate a new test.
- Even though an evaporation line is very faint, this doesn’t mean that the is an evaporation line.
If your hCG level is low, or if your urine is diluted, a faint positive test line may appear on a pregnancy test. After ingesting a large number of liquids throughout the day, it is possible for a pregnancy to fail. Having to wait for a pregnancy test to come back can be excruciating.
- Taking two tests is a simple way to ensure that your results are accurate.
- Even a faint line indicates a positive result if both are present.
- Those who are unsure of the results should wait a few days and retest their hCG levels if necessary.
- False negatives are less likely as a result of this.
- The blood or urine can be tested by a GP to get the most accurate results.
: pregnancy test- Evaporation line on a pregnancy test: What to know
What does it mean if you get a faint line then negative?
What to do if you see a faint line on a pregnancy test – If you see a faint line, the best thing to do is wait a few more days and take another home pregnancy test. By then your levels of hCG will rise enough to give you a clearly visible result. Another option is to ask your healthcare provider to confirm that you’re pregnant with a blood test, which can usually detect pregnancy a few days earlier than a home pregnancy test.
(The hormone hCG can be detected in the blood about 6 to 8 days after you ovulate, typically a few days to a week sooner than in urine.) 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. So your body may have produced a little hCG but then stopped when the embryo stopped developing.
Why did I get a faint line and then a negative?
2) Chemical Pregnancy – If you received a faint positive result on a home pregnancy test, and then received negative results the day after, it may be a sign of a chemical pregnancy (or early pregnancy loss that occurs before 5 weeks of pregnancy). Symptoms of a very early miscarriage (before 5 weeks of pregnancy) include:
A period with heavier flow than normal Low hCG levels Lack of (your usual) pregnancy symptoms (including morning sickness, fatigue and breast tenderness)
Early miscarriages often occur due to chromosonal abnormalities. Other causes of chemical pregnancies include:
Genetic abnormalities Failed implantation Low BMI Hormone imbalance
Is a faint line on Covid test second test negative?
This indicates the test is negative. Two lines – even faint lines – indicate the test is positive. The test has failed and should be retaken. If your test result is negative: Record the information on the NHS Digital Platform.
What does a faint positive look like?
Reading your at-home pregnancy test result can be tricky. How can you tell whether that subtle, extra line is a positive result—or something else? An evaporation line (or evap line) typically appears like a faded streak, while a faint positive test result looks like a lighter blue or pink line, depending on the test dye color.
