If you're 9 days past your period, I would think the line would be very dark. Could your dates be off? I would honestly get a beta hcg done before telling him, or before getting excited at least.

Just to double check. It does look positive though. It could be a evap or indent, I would test again in a couple days and if positives it should be darker! This was my FRER! My Period was 6 days late. During the time of missed period I was having milky discharge. I had sex and started bleeding for just 2 days then it stopped AF is normally heavy and lasts for 5 days. Now I have milky discharge again. I have no clue our bodies do crazy things.

Taking a pregnancy test can be a nerve-racking experience, especially when it is difficult to understand what the lines on the test mean. 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.

Positive Pregnancy Test Results vs. Test Evaporation Lines

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. Most tests also have lines that indicate that the tests are working.Oh, the dreaded confusion between a positive pregnancy test and an evaporation line.

You may already know when to take a pregnancy test and how to avoid a false negative pregnancy test. But do you know how to ensure the second line is a true positive?

evaporation line vs faint positive

There are three types of home pregnancy tests HPT : mid-stream tests, dip tests, and dropper tests. For all of these tests, the most important step is reading the instructions first. Different tests contain different instructions, and sometimes, a single box of tests contains different types, where the instructions are slightly different for each test.

When the wait time has passed, you look into the results window to determine whether the test is positive or negative.

An evap line evaporation line is a faint line that appears after a negative test has dried. Because tests are typically meant to be read three to five minutes after they are taken, the tests are still damp at the time they are read.

After this time frame passes, the urine in the test dries. As the ink makes its way across the screen, the result is displayed. Sometimes, as the ink moves across the screen, a little bit of ink will accidentally get caught in the indent line.

As the test dries and the urine evaporates, this caught ink is pulled to the surface and becomes darker. This is why the most important rule for getting a true positive pregnancy test is: do not read them after the allotted time! The results are only accurate in the time frame specified in the instructions.

Okay, so now you know how to spot a false positive pregnancy test. But what about when you see a faint line on a pregnancy test within the time frame allotted by the test? On a dip test, a positive pregnancy result is two lines of the same color. Remember the discussion above about indent lines and the way pregnancy tests work? In the same way that ink may accidentally pool in the indent line, the indent line itself may sometimes become barely visible.

If your second line appears gray or colorless, it is probably an indent and not a true positive pregnancy test.

Mid-stream tests: These are held in the stream of urine for a few seconds and then set aside for a few minutes to wait for the results. Dip tests: Pee in a cup, then dip the test usually in the form of a strip into the cup.

Dropper tests: With these types of test, urine is dropped inside the testing well using a dropper that has collected fresh urine from a cup. Evap lines can be very deceiving.

She has over a decade of experience writing about science, technology, and health, with a focus on women's health and the menstrual cycle.Millions of women in the world are trying their hardest to become pregnant.

One of the tools used to test their success is the pregnancy test. Many modern pregnancy tests exist, but the most commonly used version is the test that is comprised of a dye line. These tests usually contain two lines of dye. One line establishes a control factor that the test is working properly, and the other line confirms or denies a pregnancy. While this may seem simple enough, many women often misread their test due to an evaporation line that sometimes appears and causes confusion.

After urinating on the stick, the test is set down on a flat surface where the urine flows through the test and interacts with the dye. The dye changes color when it interacts with a hormone called hCG. HCG is a hormone that only appears when a woman has been impregnated. The average test takes about three minutes to show signs of a positive pregnancy test. Sometimes the results line changes colors immediately as the urine passes through the test.

Sometimes the line does not change colors for a few minutes. The speed of the test result depends on the amount of hCG that the woman is carrying around in her blood. The color line can range from an extremely dark color to a very light color.

The intensity of the line color depends on a variety of factors including the time of day that the woman takes the test, the amount of water that she consumed and the amount of time that she has been pregnant.

A faint line is still a positive line as long as it shows up in the appropriate testing time window. It is when lines begin to appear after the appropriate testing window that the result may be inaccurate and misread. The evaporation line is a line that may show up on the test after an extended amount of time. This evaporation line begins to show up once the urine has started to evaporate and reacts with the test strip.

Sometimes the evaporation line can mimic a positive result by causing a faint line to appear. The faint line comes from highlighted antibodies that occur when the urine evaporates.

Although sometimes identified as a false result, the evaporation line should not be confused with a positive pregnancy test when it appears after an extended amount of time. In some cases, the pregnancy test and evaporation line look exactly the same. All pregnancy tests explain the validity window to consumers. The validity window is a period of time during which the test results are valid.

The consumer is to dispose of the test after the period ends. The time period varies from test to test but is typically about 10 minutes. A faint line that shows up after the test has been sitting for 10 minutes should be ignored if no line has shown up before then.

Unfortunately, in this case, the test is negative and what is being seen is just the results of chemical interactions as the urine evaporates, known as the pregnancy test evaporation line.

To get the best results from a pregnancy test, the female should take the test exactly as the instructions explain. If a positive result is not seen within the specified testing time then the test should be discarded.

Understanding conception requires following hormone levels in an easier way. New technology allows for daily…. Test Evaporation Lines. The Pregnancy Test Evaporation Line The evaporation line is a line that may show up on the test after an extended amount of time.

I am researching the difference between an Evaporation line and a faint positive. As far as I can tell, there aren't a whole lot of differences! The Evaporation lines are usually gray and I've read they usually appear when the test is drying, normally after the allotted time for a test.

But how can you tell what color a faint line is!? I checked out the peeonastick. But I couldn't tell what color they were! Just looked like a line to me! Anyhow, this gets down to my day. Ha ha! Selfish of me I know. This morning I got up and took a test and within the first minute there was a faint line in the positive area!

It never got any darker and if I look at it now, its still there, still faint. But I have no idea what color this is! So this evening I took another test from the same brand and it was for sure a BFN. I have very difficult cycles to track so basically if I have any sign that ovulation is in my near future we try. The furthest I could be is 10 dpo. I know I am testing early and was surely not really expecting it to show this early. Advice on the difference between the two would be great!

I realize you cannot tell and I'm not inquiring! So thanks! A faint positive is just that. A positive test, that comes up within the 2 minutes, but is very faint. I have had 2 before. I have never had an evaporation line. These usually occur after 10 minutes due to heat, condensation, chemical reactions, etc.

Everyone always says even a faint positive is a positive. If you are less than a weak to your next period, there is a possibility it could show. I would think that an evaporation line would not be pink, and what are the chances tat it is a straight line right next to the pink line.

You may just be seeing what you want to see and really there is nothing there.Two colored lines on the home pregnancy test kit indicate that you are pregnant, and a single-colored line indicates that you are not pregnant 1. Sometimes, a thin and almost colorless line appears on the strip if the test is read after the allotted time.

This line is called an evaporation line and could mean different. In this post, we explain what an evaporation line is, why it appears, how it is different from a positive faint line, and how to prevent it. An evaporation line is a streak that mimics a positive pregnancy test result.

It appears as a second line but does not indicate that you are pregnant. An evaporation line is also likely to appear when the result is negative or if the test is taken too early in your pregnancy. An evaporation line forms when the urine on the testing well starts to dry or evaporate. The colorless streak usually develops as a result of the composition of certain urine specimen and might appear regardless of the brand of the kit.

Evaporation lines may appear quite frequently during pregnancy tests, and their appearance might depend on the chemical composition of your urine.

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. Do evaporation lines have color? Evap line vs. Within the recommended reaction time.
