Pregnancy Test Instructions 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:

Remove the plastic cap to expose the absorbent window. 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.) 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 Only one color band appears on the top Control (C) region. There should be no apparent band on the Test (T) region. The control line is designed to validate the test and should be crisp and clear in intensity against the white background. Positive Result: POSSIBLE PREGNANCY Distinct and consistent color bands appear on the Control (C) and Test (T) regions. Color intensity of the bands may vary according to concentration and level of hCG development. The test line is usually slightly weaker in intensity in comparison to the control line.

The pattern of increasing intensity of the test line is a much better predictor of pregnancy rather than any individual reading. 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.

Is a line on C and T positive?

What does a hCG pregnancy test look like positive

Negative Pregnancy Test – If you are not pregnant, a single window test would only show the single test line. For two-window tests, the first window would show the test line and the second window would show a single line that looks like a minus (-) symbol.

How do you know if the pregnancy test strip is positive

READING THE RESULT – POSITIVE RESULT If two coloured lines appear on the test strip, you are pregnant. One line may appear lighter than the other, but they will both be the same thickness. A faint line is more likely to occur when you are testing early and your hCG levels are low.

• See Questions 5 and 7 in the frequently asked questions.
• NEGATIVE RESULT If only one coloured line appears on the test strip this is a negative result and you are either not pregnant or you may have tested too early.
• If you are unsure repeat the test in 48 hours with a new test strip.
• See Questions 6 and 7 in the frequently asked questions.

INVALID RESULT If no lines appear anywhere on the test strip or if only the test line appears, the test has not worked properly and is invalid. This is usually due to the strip not being wet enough. Repeat the test with a new test strip ensuring that the strip is immersed in the urine sample for the full 10 seconds.

What does hCG positive test look like?

When you are tying to conceive and you miss your periods, the first thing you do before going to a doctor is take the pregnancy test at home. Taking pregnancy test at home is becoming common because of its accuracy and hassle free process. Though there is no denial that taking the pregnancy test is real easy but reading the results might be confusing for many.

1. If you are nodding your head, this article is for you.
2. In this article we tell you the right way to read a pregnancy test and other things to keep in mind.
3. Things to remember before you take a pregnancy test at home: – Sample should always be taken from the first morning urine.
4. Collect the urine in a clean and dry container.

– Do not touch the test window (the middle part of the strip) – Use the dropper given with the test kit to put urine over the strip. – Wait for 5-10 minutes (as written on the guide) to see the results. – The test should not be evaluated after 30 minutes. 1 line = Not pregnant If only one coloured line appears on the strip, the test is negative and you are not pregnant. 2 line = Pregnant If two coloured lines appear, the test is positive, which means you are pregnant. Even if the lines are light in colour, you may assume you are pregnant. False positive/false negative test There are many cases when the test that you have taken might not show the right result. Some of the cases are given below: – You have a growth, such as an ovarian tumour, that produces hCG – You are on certain medication, such as infertility treatment, that contains hCG – hCG remain in your body after a birth or miscarriage.

Would it be two lines on a hCG test if your not pregnant?

4. Confusing Evaporation Lines – If the pregnancy test instructions were not followed precisely, sometimes an evaporation line can be mistaken for a positive. Many tests show two lines when hCG is detected and one line when hCG isn’t detected, or a plus or minus sign.

1. For the line tests, sometimes, a faint-colored second line appears.
2. This may represent an early pregnancy or may simply be an evaporation line.
3. If you read the test after the recommended time in the instructions, the results might be a false-positive since the evaporation line may show up more clearly.

Avoid any confusion by following the test’s timing directions exactly as they’re written. Each test brand has specific instructions, so follow them closely.

Am I pregnant? How to read FIRST RESPONSE™ Pregnancy Test results Follow the instructions below to understand your FIRST RESPONSE™ Pregnancy Test results: Two pink lines in the pregnancy test result window means you are pregnant, A positive test result shows that the pregnancy hormone (hCG) was detected.

1. One pink line and one line lighter than the other in the pregnancy test result window means you are pregnant,
2. Any positive test result (even a very faint line) shows that the pregnancy hormone (hCG) was detected.
3. One pink line in the pregnancy test result window means you may not be pregnant, or it may be too early to tell.

CAUTION: If you choose to test early and the result is negative, you may not be pregnant or it may be too early to tell because your urine does not have enough hCG for the test to give a positive result. If you do not get your period within seven days, you should retest with another FIRST RESPONSE™ Early Result Pregnancy Test.

Which line is the hCG line on a First Response pregnancy test?

How Does a Pregnancy Test Work? – For a quick primer, at-home pregnancy tests check your urine for Human Chorionic Gonadotropin hormone, or hCG, which ramps up quickly in your body after fertilization. The lines on a pregnancy test develop color if hCG is detected. An at-home First Response™ pregnancy test works like this:

Special reagents are deposited at 2 locations on a pregnancy test strip, forming the “control line” and the “test line.” These test reagents may appear as off-white/slightly gray lines on the test strip – before or after use. In a First Response™ pregnancy test, these reagents are gold nanoparticles, which appear pink in color. They are responsible for turning the lines pink once the test is used. If no hCG is detected in your urine, only the control line will appear pink colored. If hCG is present in the urine, both the test line and control line will appear pink. Two pink lines indicate a positive result, even if one line is fainter than the other.

Some tests, like First Response™ Early Result Pregnancy Tests, are very sensitive and can detect lower levels of hCG so you can test as early as 6 days sooner.*
