For a woman trying to get pregnant, uncertainties can come in many ways. But staying positive is the key to getting positive results. Yet, there are situations that leave you startled. Such as imagine getting two different results for the same pregnancy test.

Since pregnancy tests come in different methods, like a digital test or line test. The confusion is evident if results for both sets of tests give contradictory output. What necessary steps should one take to wipe-off uncertainty clouds?

We will explore possible causes and solutions as it is not a big issue to worry about. So, stick around for a comprehensive review of this problem.

How Do Digital and Line Pregnancy Tests Work?

Working on Digital and Line Pregnancy

The basic function of digital and line pregnancy tests is to detect HCG.  It is a hormone in a woman’s body when she becomes pregnant. The only difference is a line test displays results in the form of lines, while a digital test shows them in words.

The Sensitivity Levels

Both tests have their sensitivity levels.  For instance, the first response of a line test is often higher. Hence it can detect lower levels of hCG than a digital test. Thus, a line test is generally preferred over a digital test.

What Factors Affect Pregnancy Test Sensitivity?

The pregnancy test is dependent on the hCG levels. Yet, a few other factors also play their role in determining the outcome of the test. Here are a few factors that determine the sensitivity of pregnancy levels. 

The role of the hCG hormone

One of the most important factors is the hCG hormone in both line and digital testing as it is the presence of the hCG hormone that decides pregnancy or no pregnancy. 

Differences in sensitivity between tests

Sensitivity levels are different for each type of testing. One can detect even low levels of hCG levels, making it more accurate than the other. Line testing is more sensitive than digital one.

Factors affecting test accuracy

Many factors can affect the test accuracy like timing, and low hCG levels. So, always follow the instructions mentioned in the testing kit to avoid misappropriations. 

Which Is More Accurate: Digital or Line Pregnancy Test?

Both tests can provide accurate and correct results. But a line test is a preferred testing method as it is more sensitive to hCG than a digital test. So, a line pregnancy test method is good, especially at the early stages of pregnancy.

Why Do You Get a Positive Line Test & Negative Digital Pregnancy Test?

At times, line and digital tests report contradicting results. There are different reasons to blame for. We will look at different reasons behind these mismatched outputs.

Timing

Testing too early can yield inconsistent results for a line test and digital test.

Sensitivity 

Line test is more sensitive; hence it can provide different results than a digital test.

Faulty test

Any expired test kit may result in contradicting results.

Low hCG levels 

Digital tests cannot detect low hCG levels. Hence varying hCG levels could result in different results.

Tips For Accurate Testing

Here are a few tips to get accurate results of the pregnancy tests.

Follow The Instructions 

Each test type has its set of instructions. On that account, study and follow the instructions manual before running a test.

Use First-Morning Urine For Testing

HCG concentrations are higher early in the morning. So, always run a test on the first-morning urine, as the chances of getting accurate results are higher.

Wait For The Recommended Time Frame

Allow hCG levels to rise by giving it time after you have missed your period. Running a test right after missing your expected period date may result in a wrong report.

Use A Reliable Brand

Select a reliable testing brand, as some kits do not meet testing requirements.

Seeking Professional Guidance

Professional guidance is always the best route to ensure testing accuracy. Here are a few points when you need to visit your doctor.

The importance of following test instructions

Instructions mentioned on the medical kits are also coming from professional medical practitioners. And following those instructions can lead to accurate results.

When To Consult A Healthcare Provider

If you are not sure about the results and have confusion, then consult your doctor. Because they can clear all your doubts by running extra tests. So, never leave yourself in doubt. Because seeking a professional is always better than increasing anxiety levels.

The Role Of Medical Advice In Confirming Pregnancy

Doctors are the best when it comes to determining pregnancy. They have advanced-level testing facilities like blood tests and ultrasounds.

Frequently Asked Questions

Can I have a negative digital pregnancy test but still be pregnant?

Yes! It is very much possible; as digital tests are not sensitive to low hCG levels. Hence, you can have a negative pregnancy result but still be pregnant.

Is it possible to have a positive pregnancy test one day and then a negative the next day?

Yes! Since variability in hCG levels can give inconsistent test results. In such scenarios, wait for 48 hours and then retest, as it will help increase your hCG levels.

Why is my digital pregnancy test negative but there are two lines on the first response test?

Such discrepancies are a routine thing. Generally, First Response tests are more sensitive to hCG levels, to confirm pregnancy. But, a digital test requires a certain level of hCG hormone before giving a positive result. So, if it happens, it could mean you are in an early pregnancy and nothing to worry about.

Can I be convinced that I’m pregnant even if I have a negative pregnancy test?

Yes, this phenomenon is the “phantom pregnancy”. It is a rare psychological condition where a person starts feeling pregnant but in reality, she isn’t.

My negative pregnancy test turned positive after several hours. What does this mean?

There are tests that show an “evaporation line”, which actually is not positive. So, reading results in recommended time frames can avoid misinterpretation.

If a pregnancy test is negative today, can it be positive tomorrow?

Yes, this is possible, as the increase in the hCG hormone level could result in positive results after a day. So, you need to wait and then retake the test.

What does it mean if I have 1 positive pregnancy test, 3 negative tests, and no period?

Such inconsistent results are due to fluctuating hormone levels at the early stages of pregnancy. Thus, consult a medical practitioner and seek advice. 

What does a half-positive line on a Clear Blue pregnancy test mean?

It means an invalid result. You can retake the test by using another line strip.

When do I need to retest after a negative digital pregnancy test?

The best time to retest is after 48 hours of the initial test. But, if the test again comes negative,  then consult a healthcare professional.

Final Thoughts

Two of the most used pregnancy tests are line testing and digital testing. The doctors recommend both types of tests for accurate results. Moreover, both tests are easy to run, as you can do at home.

There are chances of inconsistent results, especially at the early stages of the pregnancy. The major reason for such results is the inconsistent levels of hCG in the body.

Furthermore, line tests are very sensitive to hCG hormones. Hence they are the best test to run at early pregnancy levels. Generally, digital testing is not very sensitive to hCG hormones, thus you may not get a positive result.

Moreover, always seek professional advice especially when it comes to pregnancy. They can help and advise you to take the necessary actions to mature your pregnancy.
