The First Response pregnancy test is a brand name of a home pregnancy test kit, which has the advantage of being more sensitive giving you an earlier result and more accurate one.

Besides being more sensitive, it has the advantage of being more accurate and reliable, it is easy to use and can give results of your pregnancy test earlier. This performance makes it the best pregnancy test to buy for users. Most reviews are impressive.

However, make sure to check the expiry date that will tell you whether the kit is valid or not.

How does the First Response pregnancy test work?

It works by detecting the hCG hormone (pregnancy hormone) in your urine, which indicates the presence of pregnancy. You hold the absorbent tip of the strip in your urine midstream for 5 seconds only or you could dip it in your urine collected in a clean cup for 5 seconds.

You have the traditional line test and the Digital “YES+ / NO-” Result Test.

Both the tests take three minutes for the result and for the digital pregnancy test to display a “yes+” or “no-” response. So, be patient and wait for those three minutes to read the result.

Open the wrapper on the stick only when you are ready to use the stick. The appearance of the steady clock symbol indicates that the device is ready for use.

When to test? Morning or evening urine sample

You should use the first urine sample in the morning because it will be more concentrated. This will increase the accuracy of the test. Do not drink water until you have collected the urine sample and done the test

If that is not possible, use a urine sample later in the day, say in the evening or night, which has been passed at least four hours after the previously passed urine.

How early can First Response detect pregnancy?

The first response pregnancy test can detect hCG levels when they are very low, giving results very early after conception. This test can detect hCG when its concentration levels are as low as 6.5 mlU/ml, which are found soon after implantation, making it the most sensitive pregnancy test.

Most home pregnancy tests require levels of 20mlU/ml and more. The least sensitive home pregnancy tests require hCG concentration levels of 100 mlU/ml to produce results.


The First Response test has an accuracy of 99% when conducted by technicians and 98.4% when conducted at home by patients. This accuracy stands claimed on the day of the expected period. The earlier you test before that, the accuracy rate begins to fall.

The First Response website claims that the Rapid Results version has an accuracy of 95% while the Early Results test version approaches an accuracy of 100%.

First response claims that it is able to detect pregnancy six days prior to a missed period, and its Rapid Results version delivers the result within a minute. That’s impressive!

However, the accuracy greatly depends on when you do the test. Secondly, the rate at which hCG hormone levels start rising rapidly after implantation differs from woman to woman.

One woman may have the necessary detectable level of 6.5 mlU/ml soon after implantation while another woman may take a day or two more.

Therefore, that is another factor that may affect the accuracy of the test from woman to woman.

Again, if you are on any infertility drugs that contain hCG, it can cause a false positive result and affect the accuracy. Talk to your doctor about any medication that you are taking before you do the test.


The brand claims to give results 6 days before your next period is due, though some feel you should test yourself with your first response three days before the due date of the next period.

The results of the First Response are easy to read. After testing, the presence of one pink line means you are not pregnant while the appearance of two lines indicates that you are pregnant.

You should read the results in three minutes after introducing the first response strip to your urine.

In the digital test, if “YES+” shows on the display screen it means you are pregnant.

Faint Line

The second line may sometimes be faint making you unsure of your pregnancy. In such a case, it would be wise to test yourself again after 2 to 3 days when hCG levels will be more. However, a faint line indicates a positive result in most cases.

Positive First Response pregnancy test

If you have tested positive with the test, your next step should be to confirm this by following it with the pregnancy blood test.

When the blood test confirms the positive result, you must congratulate yourself.

Seek an appointment with your obstetrician and start your long journey to being a mother.

Negative First Response pregnancy test

A negative test can be a disappointment to those anxiously looking forward to becoming pregnant. It is possible that you have taken the test too early.

You should repeat the test again after 2 to 3 days. An ideal time to test will be a week after the missed period.

If it is still negative and you think you are pregnant, repeat with the pregnancy blood test. False negative tests are known to happen and probably your hCG hormone levels were too low to be detected or your technique of doing the test was wrong.

See your doctor for a confirmation of the result and try again.

Cost of First Response Pregnancy Test Kit

A set of three First Response pregnancy tests cost 18$, which makes it quite affordable especially if you require to be tested more than once.

There are other brands that are cheaper but they may or may not be as sensitive.
