Have you ever looked at all the home pregnancy tests?

Woah. Talk about an overwhelming aisle.

How can there be SO MANY types of home pregnancy tests?! To add to the confusion, the pregnancy test you pick up, likely isn’t cheap, so you want to be sure you’re grabbing the “right one”.

The first time I called my OB to tell them I was pregnant, the nurse’s response was – “how many tests did you take”?


Suddenly I panicked and thought I should have taken 2, or 5, or 10!

But the truth is, you don’t really need to take that many if you choose the right home pregnancy test and take it the right way.

Okay, so what’s the right one?

Before we dive into the different types of pregnancy tests and which one is best, I’m going to let you in on a little secret:

I buy the cheapest pregnancy tests I can find.

Those dollar store ones? Yeah, fill my cart up. I can get a dozen of those for the price of ONE regular test.

I do splurge and sometimes get the fancy ones, buuuuuut you get the point.

Now I’ve probably got you wondering how many pregnancy tests does this girl take?! But on to the good stuff…

Here’s what I learned in nursing school (OB was one of my favorite sections) – and the real secret to which pregnancy test is best.

Which Home Pregnancy Test is Best

Those home pregnancy tests you see, all measure whether you’re pregnant or not in the same way. They all use the same chemical found in your body (HCG), to detect a pregnancy. And a false positive, if the test is taken at the right time, is pretty unlikely. Oh, and a urine test at a doctors office is also done the same way!

Okay, so now that the secrets out, why would anyone ever buy a fancy expensive pregnancy test?

Well, there’s a few key differences.

The Differences Between Home Pregnancy Tests

How the Home Pregnancy Tests Results are Displayed

If it’s your first pregnancy test, you might have imagined how the test would tell you your results. Whether it’s a big + sign or a test that actually reads “pregnant” – you’ve got options.

The most simple and affordable pregnant test with either give you the + (plus sign) or || (two lines).

Then there are more complex home pregnancy tests. These tests can be digital and will read “pregnant” or “not pregnant”.

The first time I was pregnant there was a test that was as detailed as telling you how many weeks pregnant you are – I can’t lie, it was a pretty awesome feature. However, it’s since been recalled, so onto bigger and better pregnancy tests!

If you’re having trouble reading your home pregnancy test (like deciphering whether the tiny faint line you see is the real deal, or an evaporation line), these digital tests can be really helpful.

Pink or Blue Dye Used

If you’ve read other posts, you’ll find people have some pretty strong opinions about hating blue dye tests.

And I’m going to be honest: I used to think pink or blue dye didn’t really matter.

Then I took a test and I couldn’t read it!

Now, I consider myself educated in the realm of reading a basic pregnancy test, and I also always thought if it’s even faint, it’s there, it’s positive.

Boy, was I wrong!

So here’s the deal with blue dye home pregnancy tests. A blue dye pregnancy test has an evaporation line that depends on the evaporation of the urine. The evaporation line is right where you’d expect the + sign. And even though the evaporation line is supposed to be colorless, it often appears as a faint grey, leading to a lot of confusion.

So given the choice, grab a pink dye test. You’ll thank yourself later.

How to Take the Test

Another difference between pregnancy tests, is how you take them. Now, all over the counter tests are going to be urine tests. However there’s a few different ways to go about this.

  1. Urinate on the stick. This one is pretty direct and as simple as it can get. You go to the bathroom right on the end of the stick, cover it with the cover, and wait.
  2. Urinate in a cup and place the stick in the cup for a few seconds. Take it out, put the cover on, and wait.
  3. The least common pregnancy test (and often the cheapest) has a dropper method. Urinate in a cup and use the dropper to draw up the urine. You’ll then place three drops in a set spot on the pregnancy test and wait.

Test Sensitivity

Different home pregnancy tests have a different level of sensitivity. This is why some home pregnancy tests say you can test a week before your expected period while others say a day or two.

Here’s the deal with HCG. Your body typically does not have HCG in it. If you’re pregnant, HCG develops in cells that help form the placenta. A test that is less sensitive to HCG will need to be taken closer to the date of your missed period. A test that is more sensitive to HCG is going to give you your results sooner.

How to determine test sensitivity.

If you’re curious about a specific home pregnancy test’s sensitivity research it online or check the back of the box. This chart provides a great list of pregnancy test sensitivities.

Keep in mind – things can get confusing here. There’s a difference between “lower sensitivity” and “less sensitivity”. A pregnancy test will give it’s sensitivity as the number at which it can detect HCG. So a lower number means the test is more sensitive, which means you can test sooner.

Here’s an example: pregnancy test A has a sensitivity of 20, and pregnancy test B has a sensitivity of 100. Since your HCG starts at 0 and increases over your first trimester (then plateaus or drops) during your pregnancy, pregnancy test A is going to give you a result sooner than pregnancy test B. This chart might help:

DaysDay 0Day 1 Day 2 Day 3Day 4Day 5 Day 6Day 7Day 8 Day 9 Day 10Day 11Day 12Day 13Day 14
      Test A    Test B    

*This is just a sample chart, numbers are not exact. HCG will typically double every 2-3 days during the first trimester.

Are You Taking Your Home Pregnancy Tests Wrong? Tips to Getting Accurate Results

Now that you know the differences between home pregnancy tests, there’s a few keys to taking each one.

Test in the Morning

Many home pregnancy tests can be taken at any time of the day. However, if you’re hoping to take your test before your missed period, testing in the morning is the best idea.

Why does the morning make a difference? Isn’t your HCG level your HCG level regardless? Well, yes – if you’re doing a blood test. But since at home pregnancy tests are done through a urine test, the results can often be more diluted. Hence, the morning trick!

Your urine is most concentrated the first time you use the bathroom each day. This is because you haven’t had water all night and are probably the most dehydrated you’ll be all day. This concentrated urine is going to give you the highest level of HCG that day, which will also give you the most accurate pregnancy test results.

Follow the Window for Testing

Knowing when to take a home pregnancy test can be stressful.

For the best results, you need to follow the instructions on each individual test. Based on the test’s sensitivity, you’ll be able to take your pregnancy test anywhere from 10 days prior to your missed period, to the day of your missed period.

If the test you have is not meant to be taken 7 days before your missed period, don’t take it then! You may get a positive result, which would likely be accurate, but you may not. And depending on whether you’re hoping for a positive result or not, you’ll likely stress out even more and drive yourself crazy wondering if the results were correct or not. And then you’ll have to buy another test just to be sure!

Go easy on yourself and wait until the testing window. I know it’s hard to wait, but you want your results to be as accurate as possible.

Hopefully the next time you check out the pregnancy test aisle, it’s less intimidating and you feel comfortable choosing the right pregnancy test for you!

Don’t forget to grab your pregnancy checklists to get organized before baby arrives!
