Evap Line VS Faint Positive (Knowing The Difference)

(Evap Line VS Faint Positive) Do you see a second line on your pregnancy test? Don’t get your hopes up yet. Many people have been confused by evaporation lines. If you are looking at a very faint line, there is a possibility you are pregnant or it is just an evap line.  Evaporation lines may appear, and fortunately, they can be avoided. 

Imagine going through fertility treatments, and finally seeing a faint line after two years of trying to conceive only to find out later it was just an evaporation line on a frer. That is what happened to me!

I will answer the following questions.

  • What are evaporation lines?
  • How do evaporation lines look like?
  • How often do evaporation lines occur?
  • What are faint positives?
  • Should I worry about a faint positive pregnancy test?
  • What if I keep getting faint positive pregnancy tests, but I know I am not pregnant?
  • How to take a pregnancy test appropriately?
  • How to differentiate between evap lines and faint positive pregnancy tests?
  • Best Pregnancy Test

evap vs faint positive

What are evaporation lines?

Evaporation lines are faint lines that appear on pregnancy tests after the urine placed on the pregnancy test dries up and they appear exactly where a positive line would be. This occurs when a chemical reaction takes place in the mother’s urine.

How do evaporation lines look like? What color are evap lines?

You probably already looked up photos of evaporation lines; however, you probably thought it looks exactly like a positive pregnancy test. Surprisingly, they are actually different. Usually, evap lines are colorless lines or streaks (grayish) and a bit thinner than positive lines. Look closer you may be able to figure it out.

Tip: Avoid blue-dyed pregnancy tests; they may give evap lines a blue color. That is why you see many women google “evap line vs faint positive blue dye”. Blue dyes are known to give false positives. If you do take one, try again later and see if it gets darker. 

How often do evaporation lines occur?

Evaporation lines don’t happen all the time. As mentioned previously, evaporation lines are a result of some kind of reaction in the woman’s urine. Some women may see this line a lot while others never. That is because everyone’s urine is unique and composed differently.

What are faint positives?

Faint positives are faint lines that appear on the pregnancy test because of the low amount of HCG present in the urine, but they do indicate that you are pregnant. They have color and are equal in size to the control line.

Sometimes you may get a faint positive because

  • You tested too early.
  • You may have ovulated later than you thought
  • A sign of a chemical pregnancy 
  • The start of a miscarriage – Read this article to help with miscarriage anxiety.
  • The pregnancy test is not sensitive.
  • Your urine is too diluted.

Usually, faint positives are seen within 5 minutes of taking the pregnancy test. However, if you do see a faint positive after 5 minutes you still may be pregnant because low amounts of HCG may take time to appear on pregnancy tests. 

If you choose to test early, make sure you buy a pregnancy test that can detect very low amounts of HCG or you may get a false negative. One of the best pregnancy tests for detecting low HCG is the First Response Early Result Pregnancy Test. It was able to detect HCG as low as 6.5 MIU/ML. If you would like to read more about the best pregnancy tests, click here. 

If you would like to buy a very sensitive pregnancy test that can detect a small amount of HCG, click here. 

Should I worry about a faint positive pregnancy test?

No, you definitely should not worry. You can have a normal pregnancy even if your HCG levels are low. The important thing is that it increases. So, you can take another pregnancy test in 48 hours and see if it gets darker. If it stays faint, there is a possibility of a chemical pregnancy, miscarriage, or ectopic pregnancy. 

*** I am not a doctor. Inform your doctor about faint positive pregnancy tests. 

What if I keep getting a faint positive pregnancy test but I am sure I am not pregnant?

Getting a false positive does occur. It could be for the following reasons:

  • Fertility Medication (Trigger Shot)
  • Hormone Imbalance
  • Molar Pregnancy: An abnormal pregnancy that causes a tumor to grow.
  • Epithelial Cancer Cells and Other Health Problems (Ovarian Cysts)
  • Was recently pregnant, had a miscarriage, an abortion, or a chemical pregnancy, and have leftover HCG.

How to take a pregnancy test appropriately?

  • Choose a sensitive pregnancy test. 
  • Read the instructions on the pregnancy test. Each pregnancy test has its own instructions. 
  • Wait until your miss your period.
  • Use a cup to collect urine.
  • Place the pregnancy test in the cute without letting the urine touch the test line. Leave it in for as many seconds as the pregnancy test says. 
  • Take it out and use a clock to wait. 
  • Don’t read the pregnancy test beyond 5 minutes. Use another pregnancy test when in doubt. 

How to differentiate between evap lines and faint positive pregnancy tests? (Evap Line VS Faint Positive)

Telling the difference between evap lines and faint positive can be quite difficult. However, this difficulty can be solved by understanding the difference between them.

Evap Lines

  • Appear after the time limit of reading the results of the pregnancy test (usually after 5 minutes).
  • Usually don’t have any color (sometimes they do) and are very faint.
  • It can disappear after a few hours.

Faint Positives

  • Appear within the time limit of readability (usually within 5 minutes).
  • Have dye color (usually pink or blue color).
  • The faint line shows on more than one pregnancy test.
  • A digital pregnancy test says your pregnant. 
  • It will not disappear after a few hours.

evap line vs faint positive

How can you avoid evaporation lines?

  • Read the pregnancy test within 5 minutes.  Read the instructions on the pregnancy test because sometimes pregnancy test results must be read after two minutes.
  • Take another test if confused about whether the line is positive or an evap line. If the same faint line shows on the second pregnancy test, it is most likely a faint positive.
  • Wait until you miss your period by one week.
  • Make sure your urine is concentrated (urine should be dark). Morning urine works best. 
  • Take a digital pregnancy test. it would be much simpler. 
  • Make sure not to wet the test line. Disregard the pregnancy test if you do. 
  • Use a very sensitive pregnancy test. 
  • Buy a group of pregnancy tests from Amazon. I recommend Accumed pregnancy tests because you can take more than one at a time for a very low price and see if they all have a faint line or only one or a few.

Did you just find out you are pregnant, I recommend creating a baby registry with Amazon. Click here to do so.   It is never too early to create one, and It is always free! Have fun with it!

Best Pregnancy Test (Evap Line VS Faint Positive)

If you want a guaranteed yes or no, then take this reliable pregnancy test that will not confuse you between evap line vs faint positive.

First Response Early Detection Pregnancy Test

The first response early detection test is only 10 dollars for three tests, and it is the most reliable pregnancy test. This test can catch very low HCG levels. You can get a positive six days before your expected period. It is 99 percent accurate on the day of your expected period. And, guess what. You can download an app called EasyRead, and you can take a picture of your pregnancy test and download it to the app. It would tell you if you are pregnant or not. There are three tests in the pack, so you can take more than one for confirmation.

If you would like more information, I recommend reading Mama’s Natural “What Does an Evaporation Line on a Pregnancy Test Mean“.

Also, I am very good at differentiating between evap line and faint positives, so leave a picture of your pregnancy test below, and I will tell you what I think!

I have had 6 different what looks to be faint positive tests. But they are very very faint. Surely it couldn’t be an evap on every one of them, could it? My tests I’ve taken at night have shown up immediately the second line whereas in the morning it’s there just not as quickly.

My periods are erratic right now after a pregnancy loss this summer but should come about now based on when I ovulated. I took this test this morning. The line is faint, but it is the same width as the control line and showed up in the first few minutes, what do you think?

Hi im bri, i recently got off birth control in March and been ttc for about 6 months. I have been spotting 9 days before my period and it’s getting lighter but hasn’t stopped. This has never happened to me & I’m with 1 partners only. Im 3 days from my expected period date and took a test today. I think it’s negative but after reading these, maybe its just evaporated. I want a child so bad i just want to see that line. Im hoping its still too early. After reading this, i see tests that look very similar to mine and are getting comments saying it’s pos. Thought I’d share my pic & take another test in 48 or longer.

Hi,
So I gave birth in july this year and am exclusively breastfeeding however my son started sleeping through the night early. I got my first post partum period in August but have since missed the last two. I took many pregnancy tests and this one is the only one that came back positive. Does it look positive to you or an evap? I still have not had another period and have not bled at all. Thank you for your help.

Hi there,
I did a test a few days ago, left it and looked at it again and it showed up positive (not sure if it’s an evap line but it seems pretty dark to me). I’ve then done loads more and they’re all coming up negative? I’m on the pill so I don’t get periods but my boobs have been hurting me for the past week or so and I’ve been having back pains, and then today my whole body has been aching. What do we think, pregnant or evaporation ? Thank
you x
