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

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 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..

Best Pregnancy Test

If you want a guaranteed yes or no, then take this reliable pregnancy test.

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 evaps and postives, so leave a picture of your pregnancy test below, and I will tell you what I think!

We’ve been TTC for eight months and have a thirteen month old. I’ve been PRAYING for a positive however I looked at this test way after the three minute mark. I’m not sure if it’s an evap line or a positive. I took it at 8am this morning and it’s now 10:20 pm so I don’t know if an evap line would’ve stayed there this long.

Hi, I have tested 3 times now. All faint lines showed up before 5mins. I can understand if it is a positive as I would be extremely early as I took the first test as my friend took a test and she was pregnant so asked me to do one too I said it won’t be positive but did it anyways and then saw the second line show up within 1min….. but is it a faint or evap line?? On all 3??

I am 5 days late, I believe I ovulated on the 28th or the 29th of last month. I have been getting only faint lines within 5 minutes of testing using first early morning urine. I have pcos so I am second guessing myself if I am I pregnant. We’ve been trying for two years now. Are these faint lines evap or positives? Sorry for my crappy photo.

Also, if you drank a lot before taking them it can dilute your urine and give you a false negative. It happened when I was pregnant with my son, two positives, then the next day went to get it confirmed at my urgent care and got two negatives, had them draw blood and there was my positive. Fluids dilute your urine if you have a lot.

Hi!! I have taken so many tests during this month and I think I finally have gotten a positive result. When I woke up this morning I took another test and it came back negative. My last 5 tests have been positive. I will in life a picture of all of the tests I’ve taken. Is this an evaporation line or a faint positive? I tried a pink dye test but I’m afraid it won’t pick up the HCG in my Urine. The blue dye test have come back positive each time except this morning

Hiii!! I need some help. I took an early first response test Monday morning. It came back positive with in seconds. I waited a while and took another yesterday morning as well. It was also positive but not a vivid is was faint. So I made an appt that day. I had my blood drawn and was to go get beta hcg level tested. I got the results back today and I was at less than a 1. So my blood test came back negative. I also tried clear blue tests and several other urine tests that came back negative. First response was the only positive one. With my negative blood test I’m just not sure what to believe. My period is also 2 days late. Please help!!!
