Buy First Response Pregnancy Test
A positive (pregnant) test result shows that the pregnancy hormone (hCG) was detected, which normally indicates pregnancy. You must see your doctor to confirm that you are pregnant. If you test positive, but think you may not be pregnant, you should check with your doctor.

Only medications containing the pregnancy hormone (hCG) can affect the result (e.g., A.P.L., Pregnyl, Profasi and Pergonal). The test should not be affected by hormone therapies containing: Clomiphene citrate (e.g., Clomid and Serophene); alcohol; painkillers; antibiotics; or the contraceptive pill.
If you have a positive pregnancy test, you will want to schedule an appointment with your doctor. They will guide you further in how to care for your pregnancy. They will also be the person with whom you can share concerns or ask questions, even before your appointment.
Once the body begins producing more hCG, its amount in the blood and urine roughly doubles every two or three days for the first eight to nine weeks of pregnancy. After implantation, someone might have anywhere from 5 to 50 mIU/mL of hCG in their pee (mlU/mL means milli-International Units per milliliter, a standardized unit).
In addition, in our own (unscientific) testing, this test gave the clearest positive reading to a very dilute solution of pregnancy pee. As you can see in the photo, the First Response wand (at bottom) showed a very clear positive response with a strong fuchsia line, while the other pregnancy tests barely registered faint blue marks.
There are other rare situations where a more sensitive test could be more likely to give false positive results. For example, hCG can increase during perimenopause. One study found that 1.3% of home pregnancy tests taken by women ages 41 to 55 would be false positives. The manufacturer reported to the FDA a similar rate of false positives for this age group.
Similar to First Response Early Result, Clearblue Early Detection can detect pregnancy five days before an expected period 71% of the time (that goes up to 94% four days before, 98% three and two days before, and 99% a day before an expected period). Unlike other Clearblue pregnancy tests, this wand test also uses pink lines rather than blue, which some people find easier to read.
When an egg is fertilized, your body starts producing hCG. During early pregnancy, hCG levels double every two to three days and peak by the end of your first trimester. Pregnancy tests look for how much hCG is present in your urine.
In general, home pregnancy tests are more accurate the longer you wait to take them. Testing on the day of your expected period, or after, will yield a more definitive answer. If you test too early (think just days after ovulation), you could get a false negative and have to test again later.
The new kid on the pregnancy test block, Natalist makes a test that is over 99% accurate, can be used up to five days before your missed period and is easy to use, with clear directions in both English and Spanish. The design is sleek and modern, and the packaging comes with a nice little note. The company is also woman founded and 100% plastic neutral.
Manufacturers who market tests in both Europe and the USA tend to conform to these definitions across both markets (e.g. Clearblue, First Response, and EPT brands). Device accuracy, which is usually considered to be the percentage of correct detection of negative and positive results (at concentrations of hCG greater than test sensitivity) using urine samples from women seeking to know pregnancy status, are also often calculated. However, it is unclear as to whether other tests available in Germany conform to these definitions and it is therefore not possible to make objectivecomparisons between tests based on their packaging claims.
Unfortunately, no recent studies have investigated home pregnancy test performance, and indeed, there are no historical studies evaluating the myriad tests now available on the German market. In the absence of any available data on test performance and the lack of standardisation for evaluating test credentials, any declaration of test accuracy on the package labelling is potentially misleading.
The type of test format is another factor that can influence the accuracy of pregnancy tests when used at home. Home pregnancy tests are available in three main formats: strip, cassette and midstream test sticks. Strip tests have no casing or sample application wick; they therefore require women to collect a urine sample and then dip the small strip-like device into the sample until the urine reaches a prescribed line on the strip. The cassette format requires women to collect a urine sample, following which the user has to add a small quantity of the collected urine to thecassette-like test device using a plastic bulb supplied with the test. Both the strip and cassette test formats were primarily designed to be used by healthcare professionals in a clinical setting. However, they are also available for women to use at home. In contrast, the midstream test stick format was specifically developed to enable women to carry out pregnancy tests easily at home. Midstream test sticks consist of a stick with an absorbent wick at one end, which is placed in the urine stream or dipped into collected urine to obtain a sample.
Another cause of observed false negative results for home pregnancy tests can be due to unusually high concentrations of hCGβcf, the core fragment of β-hCG, which can occur in later stages of pregnancy 39. Tests recently cleared for marketing in the USA by the Food and Drugs Administration have been required to demonstrate that they do not produce false negative results when used in later pregnancy. European guidelines require manufacturers to do their own risk assessments; however, specific performance requirements are not defined in the directive.More prescriptive European guidelines would be beneficial to ensure that similar risks are taken into consideration by all manufacturers.
New! FIRST RESPONSE Early Result Pregnancy Test can now detect the pregnancy hormone, hCG, 6 days before your missed period. Patent pending, Polymeric Amplification Technology (PAT) allows only FIRST RESPONSE to detect the pregnancy hormone at lower levels than ever before. It is the ONLY pregnancy test that detects the pregnancy hormone 6 days before the day of the missed period, which is one day sooner than any other test on the market.
FIRST RESPONSE Early Results Pregnancy Test now has patent pending technology that can detect the pregnancy hormone, human chorionic gonadotropin (hCG), up to six days before the day of a woman's missed period with unsurpassed accuracy -- one day before any other at-home pregnancy test available on the market.
"A pregnancy test with results this early sets the stage for a healthy baby and a healthy mother. This latest advancement means pregnant women can initiate a healthier lifestyle even sooner in the critical first stages of a baby's development," said Mary Jane Minkin**, MD, board-certified obstetrician/gynecologist in private practice in New Haven, Connecticut, and a Clinical Professor of Obstetrics and Gynecology at Yale University School of Medicine. "Women who want results quickly will undoubtedly have less anxiety when taking this at-home test."
FIRST RESPONSE works when a woman's urine comes in contact with a specially treated strip in the plastic housing of the pregnancy test device. After three minutes, the test result appears in the housing window on the stick. Two pink lines indicate that hCG has been detected (pregnant); one pink line indicates that hCG has not been detected (not pregnant). The patent pending Polymeric Amplification Technology (PAT) has increased the overall sensitivity of the device, resulting in better detection of the pregnancy hormone.About FIRST RESPONSE Products

There are 2 ways you can use your First Response Pregnancy Test, and each will give accurate results, so the way you want to test is entirely up to you. Begin by removing the pregnancy test from its wrapper and removing the protective cap from the absorbent end of the test, then take your test in one of the following ways:
It will take 3 minutes for the pregnancy test to work, and during this time you may see the pink colour moving along the result window. This means the test is working properly. Keep your test on a flat surface as you wait.
When you take your First Response Early Detection pregnancy test from the first day of your expected period, your results will be over 99% accurate. Although you can use this test up to 5 days before your expected period, your test may be less effective the earlier you test. This is why many women who test early choose to take a second test on the day of their expected period, to confirm their results with more accuracy. Laboratory testing of these First Response tests saw the following results:
These and many other pregnancy tests will say that they can detect pregnancy days before your first period. For example, First Response's Early Result Pregnancy Test states it can tell if you're pregnant up to 6 days before a missed period. However, doctors agree that if you're looking for the most accurate result, it's best to wait for the hCG levels to be detectable in the urine.
"Waiting for a missed period and [testing your urine] first thing in the morning is going to probably be the most accurate way, other than going to your doctor's office," Ross says. "If you're checking a few days before your period, whether it's digital or non-digital, it's not going to be as accurate as if you're testing a day after your period was expected to come." 041b061a72
