How does a pregnancy test look like when it positive

Instructions for using your pregnancy tests

If you miss a period, please take a pregnancy test. We have given you two pregnancy tests for this purpose. If you need additional pregnancy tests, please contact us by phone or email.

When you have a POSITIVE PREGNANCY TEST, please CONTACT US TO SCHEDULE YOUR ULTRASOUND. You can call us at 919-843-8246, or email us at .

Instructions:

1. Remove the plastic cap to expose the absorbent window.
2. Point the absorbent tip (with 5 small openings) directly into the urine stream. Take the sample for at least 7-10 seconds, to ensure that an adequate sample is collected by the testing device. (Another technique is to collect the urine into a clean container and dip half of the absorbent pad for at least 10 seconds.)
3. Re-cap the device and place it horizontally on a clean, flat surface. Wait 5 minutes for the test to finish processing.

RESULT INTERPRETATION

Negative Result: NOT PREGNANT

Positive Result: POSSIBLE PREGNANCY

Invalid Results
If there is no visible control line, discard the test. Repeat test with a new device.

STORAGE
Store pregnancy tests at normal room temperature, between 36°F and 86°F. Discard unused pregnancy tests after the expiration date, which is stamped on each sealed pregnancy test. Avoid prolonged exposure to direct sunlight, moisture, heat, and other related conditions.

DISPOSAL
Urine samples and used test devices are potentially infectious, so please keep them away from direct contact with objects. Proper handling, hand washing, and immediate disposal is recommended.

Eager parents-to-be are not famous for their patience, especially when it comes to checking — and rechecking — whether or not their baby-making efforts have paid off. If you're among their ranks, chances are you've stockpiled home pregnancy tests and use them regularly. 

But though they’re an affordable, easy-to-use and convenient way to find out if you're expecting, home pregnancy tests can be confusing, especially if you are very early in your pregnancy. Here's a guide to deciphering what those little lines or plus signs mean.

What does a faint line on a pregnancy test look like?

Depending on what kind of pregnancy test you use, you'll see a plus or minus sign or, more commonly, a line or two in the window that reveals results.

Make sure you read the instructions on the pregnancy test packaging carefully so you know exactly what you should be looking for.

If you are pregnant but very early in your pregnancy, the line or double line on your pregnancy test will likely be barely visible, like a smudge of chalk. If you're farther along and the hormones are flowing, the line or lines will resemble marks drawn with a Sharpie.

If there's no line or positive result, it doesn't necessarily mean you're not pregnant (though that is a possibility). Instead, it could simply mean that there's not yet enough human chorionic gonadotropin (hCG), the hormone produced by cells that will become the placenta after implantation, to be detected by the test.

What does a very faint line on a pregnancy test mean?

A very faint line on a pregnancy test usually means that implantation has occurred and you're in the early stages of pregnancy. But you'll want to test again a few days or weeks later to see if that line has become thicker and darker, meaning your pregnancy is progressing — and you can safely start getting excited!

It is possible to see a faint line on your pregnancy test and get your period a few weeks later, meaning that you're not actually pregnant, or were only briefly pregnant. This doesn't mean the test didn’t work, but you might have experienced a very early and common pregnancy loss called a chemical pregnancy. It could also indicate other kinds of early pregnancy losses like an ectopic pregnancy.

As upsetting as it can be, you probably never would have realized what had happened if that faint line hadn't clued you in, and the event will have no impact on your ability to get pregnant again. In fact, it can be considered a positive because it's proof that you can get pregnant.

The best way to know for sure that you're pregnant is to schedule an appointment with your OB/GYN and get a blood pregnancy test to confirm the pregnancy. This provides a number for your hCG level, which allows your doctor to see whether everything is progressing well in the early stages.

What does a positive pregnancy test result look like?

A positive pregnancy test result will typically either show up as a plus sign, two double lines, or one line in a results circle or window, though there are other kinds of test results, including the digital ones that show the word "yes" or "pregnant" when they're positive.

Can a barely visible pregnancy test result be negative?

A barely visible pregnancy test result usually can't be negative — because it detected hCG — but it might indicate a false positive for actual pregnancy or an early pregnancy loss. You can also get a false negative result.

Most home pregnancy tests claim to be up to 99 percent accurate — and when tested by lab technicians in ideal settings they probably are — but studies of home pregnancy tests used in the real world by women at home suggest they're slightly less reliable.

Here are instances in which you might see a faint line on a pregnancy test but are not actually pregnant or have a nonviable pregnancy:

• Menopause. If a woman in perimenopause or menopause misses her period and takes a pregnancy test, the results sometimes (but rarely) show up positive due to abnormally elevated levels of luteinizing hormone.
• When you're taking fertility and other medications. False positives can be caused by traces of fertility drugs or other medications containing hCG (though it's unlikely). If you received an hCG injection as part of fertility care, levels can remain elevated for at least seven days afterwards even if you're not pregnant. 
• When you have an early pregnancy loss. A false positive can also indicate a recent chemical pregnancy, ectopic pregnancy or other type of early pregnancy loss.
• Illness. Very rarely, some cancers that interfere with hormonal production can result in a misleading pregnancy test.

Here's why you might be pregnant yet see a negative result on your pregnancy test:

• It's too early. If it's very early in your pregnancy, concentrations of hCG may not have reached levels that are detectable yet. The best bet is to wait a week and test again.
• You checked results too soon. Of course you're impatient! But give the test the full time recommended on the package instructions to reveal results. You can use the timer on your watch or a kitchen timer to be sure you're waiting long enough.
• Your urine is diluted. Good for you for staying hydrated. But if your urine is too diluted for the test to detect hCG, the results might be inaccurate. However, though taking the test first thing in the morning, when your urine is the most concentrated, is often recommended, it's not necessary because modern-day pregnancy tests are super sensitive and can pick up hCG whenever they're used.
• Human error or expired test. If you didn't follow the instructions to the letter, or have a home pregnancy test that's expired, there's a chance that the results might be inaccurate.

If you get a faint positive pregnancy test, are you definitely pregnant?

If you get a faint positive pregnancy test, you are almost always pregnant, but it may be too early to celebrate. Home pregnancy tests differ in their ability to detect a pregnancy in women who have recently missed a period, either because of a chemical pregnancy or other reason.

If you have a negative test but think you might be pregnant, or vice versa, repeat the test one week after your missed period or talk to your practitioner. And remember, a blood pregnancy test from your OB/GYN is always more accurate.
