6 Best (Most Sensitive) Pregnancy Tests

You go to take a pregnancy test, and you see “negative.” Before you break the news to everyone, it’s a good idea to make sure you’re using the right test on the market.

There are dozens of pregnancy tests available, but which is the best pregnancy test? Most tests will use a similar pregnancy detection method (more on that soon), so they are all fairly accurate. The main difference is how sensitive a test is (yes, accuracy ratings are important).

How Pregnancy Tests Work?

Before reviewing any product, it’s important to know how these tests work. It’s a scientific method that is used in virtually every over-the-count test. Using a woman’s urine, pregnancy tests are able to determine if a woman is pregnant or not.

A special hormone, called hCG, is found in the urine of a woman that is pregnant, and is produced by the placenta.

All of the tests, aside from blood tests, will use a woman’s urine to find a sufficient amount of the pregnancy hormone hCG. This hormone takes a few weeks to build up to a sufficient level for detection.

Most tests will have a sensitivity of 20 – 25 miU/ml. The lower this measurement is, the earlier the pregnancy can be detected. The best early pregnancy test will have a low miU/ml. The absolute minimum amount of hCG that can be detected is 5 miU/ml, but no current over-the-counter tests go quite this low.

Sensitive tests will produce accurate results faster than non-sensitive tests. Some tests are able to accurately find the hCG hormone 6 days earlier than others.

6 Most Sensitive, Accurate Pregnancy Tests on the Market

1. First Response Early Result (Our Winner!)

One of the best today. First Response offers this test with a sensitivity of 6.3miU/ml. The manufacturer states that the test is able to accurately predict pregnancy up to 6 days earlier than the competition.

The #1 best seller category across the U.S. First Response is the premiere choice for one reason: it offers this test with a sensitivity of 6.3miU/ml. Due to the lower miU, this test can accurately predict pregnancy up to 6 days before a woman’s missed period.first_response

Furthermore, the test also has a 99% accuracy rate when used the day after a missed period.

Pros

  • Extremely accurate – the most accurate pregnancy test on the market!
  • Low level of sensitivity
  • Detects pregnancy up to 6 days before a missed period

Cons

  • Lines can be faint

Usage

Usage is simple and easy. A woman simply urinates on the front of the test and waits for the test to display one or two lines.

  • One line means not
  • Two lines means pregnant.

Simple to read and use, the test will display the result in just 3 minutes. It’s recommended that the test be used in the morning and 6 days before a missed period for best results

Technical Information

There are a few technical and statistical specifications that First Response provides:

  • It’s the only test that can work 6 days before a missed period.
  • Tests show that 76% of woman used First Response 5 days before their missed period with 100% accuracy.
  • Women that use this test 4 days before a missed period can expect an accuracy level of 96%.
  • A 99% detection rate is seen when the test is taken 3 days before a missed period, or after the missed period.

As far as miU/ml is concerned, the manufacturer has not listed the exact detection level. While many users state the test indicated pregnancy early on, one study conducted by CBS shows that First Response can predict pregnancy with as little as 6.5 miU/ml. This is such a low amount that it is close to the amount of hCG doctors would expect near the date of implantation.

2. Clearblue Easy Earliest Results (Another Sensitive Product)

Click Here to Check Price/ Review

Pros

  • Easy-to-read digital display.
  • Detection up to 5 days before a missed period.
  • Comes in a pack of 3.
  • Includes week estimator.

Cons

  • The week estimator is not highly accurate.

The week estimator is not highly accurate, with many women stating that the test indicated “1-2” weeks in the morning, and during a same-day retest, the results were “2-3” weeks. The biggest issue is urine dilution, which may lead to the wrong week estimator results. The estimator measures the amount of hCG in the body, so there is a certain level of error involved.

Not as sensitive as our last choice, Clearblue actually has a sensitivity level of 25 miU/ml, but this does not mean it’s not as sensitive as the competition. Oddly, this test was able to predict 80% of pregnancies on the first day after a missed period with 100% confidence when the test was positive.

Negative tests had an accuracy rate of 67%.

Usage

Usage is as simple as First Response, but a little easier to actually read. The way to use this is simple:

  • Urinate on the stick.
  • Wait until the LED display illuminates.

It’s really that simple. The display will say “pregnant” followed by how many weeks pregnant a woman is according to the estimator. This is indicated in the following manner:

  • 1-2 for 1 to 2 weeks into pregnancy.
  • 2-3 for 2 to 3 weeks into pregnancy.
  • 3+ indicates that you’re 3 or more weeks into pregnancy.

One of the major benefits to this test is that it does not have hard-to-read lines, and the wait time is very minimal. Ultimately, this is the easiest test on the market to reads, and you won’t have to worry about test strips drying out, which does occur on occasion.

3. Wondfo Pregnancy Test (Best Medical Pregnancy Test Strips)

Click Here to Check Price/ Reviews

The Wondfo pregnancy test strips are medical-grade and highly accurate. Unlike other tests on our list, these tests are strips, and they come in a pack of 25, although a pack of 50 can be purchased.

Despite the large number of strips, these tests are around the same price range as other tests – so you can keep testing minus the cost.

Pros

  • 25 strips are included.
  • The test takes 5 minutes to display results.
  • Detects pregnancy early on.

Cons

  • No accuracy statistics available.

In terms of accuracy, there aren’t statistics listed by the manufacturer. However, tens of thousands of consumers have used these test strips with a high level of accuracy. It’s safe to assume the medical-grade strips come with as much accuracy as the two previous tests on our list, but remember, this is a 25 miU/ml test, which doesn’t come with a 6 or 5 day early prediction statement.

Usage

Usage is also a little different with test strips than with other tests. This is what you’ll need to do:

  • Urinate into a cup.
  • Place the test strip in the cup.
  • Let the strip sit in the urine for 3 seconds.
  • Take the strip out and place it flat on a table.

Once this is all done, you’ll have to wait about 5 minutes before the results are seen. Results are a little more difficult to read with this model than other tests. This is done in the following manner:

  • Positive: Indicated by two solid lines.
  • Negative: Indicated by a top solid line.
  • Invalid: Indicated by no lines or by only a bottom line.

The top line is a control line that will display regardless of the level of hCG in the urine. If the line is not displayed, this means the test is invalid and you will need to redo the test.

4. One Step Pregnancy Test Strips (Best Early Pregnancy Test Product)

Click Here to Check Price/ Review

One Step has a very low sensitivity level of 10miU/ml. Using strips, these tests are very accurate and are great at early pregnancy detection. Many users have been able to predict their pregnancy well before their missed period thanks to One Step

Users state that they’ve successfully tested positive 6 days before their missed period.

The one note of caution with this test is that they’re often very hard to read due to the strip’s color change.

 

5. New Choice Pregnancy Test (Cheap Pregnancy Test But Effective!)

Click Here to Check Price/ Review

If you’ve been to Dollar General or Family Dollar, you have passed the New Choice brand in the aisle. Don’t let the low price fool you – these tests work great – and they’re much cheaper than the competition

This is the 3rd most sensitive test on the market, however.

FDA approved, these tests have a 99% accuracy rate, according to the manufacturer, and have a sensitivity level of 25 miU/ml. These tests are just as good as the competition (except the first two above) and they cost a fraction of the price.

 

6. ClinicalGuard Pregnancy Tests (Just Another Alternative)

Click Here to Check Price/ Review

Offered in packs of 20, these are actually test strips and not the normal “+” or “-“ models that you may be used to seeing. Using bands of color, these tests also test hCG and have a sensitivity of 25 miU.

The best part is that one package comes with a lot of tests, so you can retake the test without having to buy another one any time soon.

Final Verdicts

The vast majority of tests on the market today have a sensitivity level of 25miU/ml, which means that they will be most accurate 12 – 15 days after implantation. This is often a day or two after a missed period. For women that have been trying to get pregnant and are eager to find out if they’re positive, it’s best to use one of the highly sensitive tests above.Woman holding negative pregnancy test

Please note that even the most sensitive pregnancy tests should be verified by a medical professional.

Using a test at the optimal time, as close to a missed period as possible, will ensure that you have the most accurate results possible. If a test is negative but you believe you are pregnant, doctors recommend waiting at least a week before taking another test so that the hCG levels in the urine can accumulate to detectable levels.

How Sensitivity Is Rated

When implantation occurs, the body will start to produce the HCG hormone, also known as the pregnancy hormone. This hormone is produced only when a woman is pregnant and is produced by the placenta.

It’s a highly accurate way to test for pregnancy, but it has its flaws.

Sensitive tests will need to pick up at least 5 miU/ml of the hormone in the urine before displaying positive results. However, most tests require a much higher level of hormone in the range of 20 – 25 miU/ml. The lower this unit of measurement is, the more sensitive the test will be.

In terms of time, 5 miU/ml of hCG will take 6 days to reach 20 miU/ml at the very minimum. It takes approximately 3 days for the amount of hCG in the body to double. This means it can take well over a week to learn that you’re pregnant from the time of implantation.

  1. Afternoon,

    I was hoping to find the answer to a quick question I had. I have been looking at becoming pregnant recently and have been using the First Response Early Result Pregnancy Test. I have been doing some research and found here http://www.mostaccuratepregnancytest.com that the clearblue digital kit is one of the most recommended. Do you know if there is a substantial difference between the two or are they about the same? Any time difference between when they will let you know earlier?

    Thanks!

    • The digital is recommended because there are no lines to look at, it just states “pregnant” or “not pregnant” but the first response early result is more sensitive so you can get a positive result usually a couple days sooner than with the digital.

  2. My HCG blood work is <5 and they want me to retest in 48 hours. Is there a test that will test if I'm positive now at the HCG level?

  3. i missed my periods and today is 8th day of missing my periods…. last time was on 19 feb…. after nothing…! should i test? or test in the morning!

  4. Hey! I have a normal cycle of 26 days. I had my HCG level tested yesterday and it was at 25. Is that too low for being 2 days past my expected period?

  5. Hi my last pregnant is march 14 and i did pregnancy test last april 9 and i use the clearblue digital kit and its positive and i did again a test last april 10 with the other brand and its show 2 lines but the 1 lines is faded what its mean??thank you

    • You are most likely pregnant. It’s more often you get a false negative than a false positive. Try taking another test in a few more days as HGC levels tend to increase throughout the week (if pregnant). Take care!

  6. Hi last pregnant is march 14 and i did pregnancy test last april 9 and i use the clearblue digital kit and its positive and i did again a test last april 10 with the other brand and its show 2 lines but the 1 lines is faded what its mean??thank you

    • I have had 3 very very faint lines on my wondfos and a negative frer that really gives me hope I’ve been ttc for over 3 years I’m 12 dpo today and have been trying not to panic because I can’t seem to get a positive on CB or frer 😭😭

  7. I had a period 2 weeks after I had sex but this month my period is late but I started geting blood on the toletpaper but no blood no my underwear iv been filing sick and tired an peeing s lot and craving chocolate all the time is it passable for me to be pregnant

  8. I was due the 4th, but missed my period 4 days late. Been taking pregnancy tests clear blue, first response, first signal, ultra pregnancy test, & all negative. I have all the symptoms of being pregnancy except a positive test. When do I need to retest??

  9. & my cycle is 23 days in between, & my last period was July 12, my one for August suppose to be the 4th,& not a sign of my period not even a positive test either. Me, & fiancee wants this soooo, bad we’re both on the edge of our seats, & anxious everytime a negative pops we get more, & more discouraged (sigh)

  10. My period was due on 22nd November 2017 I’m 11 days over due I have done 6 pregnancy tests including this morning but still there is no sign off pregnancy what do I do any idea anyone please

  11. Now that first response has brought back the old design, they are no longer as sensitive. I’ve been watching women get positives on other tests, long before they get a positive on a first response. The indent lines on first response are horrible, and there are scratches on the test strip. It wasn’t like this before. I do wonder when they had to recall the curved tests they chose not to make the new but old design tests as sensitive so as not to show chemicals and such? They are definitely not Women’s go to anymore. Bummer. Clear blue did something similar and took their 5 days before tests off the shelf, and replaced it with the rapid result. Those ones are more for day of or missed. It would make sense that the companies would make their testst less sensitive, however first response needs to be honest about it.

  12. I have taken wondfo and have gotten very very faint positives then took a frer and it was negative.. considered for a moment it was an evap.. but it appeared within 3 mins. So I’m not sure whats what. I’m so confused been ttc for over 3 years.

  13. Hello, I had my period on the 3rd April and had unprotective sex 11th and 12th April, also on the 21st April, around 1 pm on the 21st I started seeing brownish discharge when I use the toilet and wipe, it continues until the 22nd and stop in the afternoon, I tested twice and got negative result, can i be pregnant?
