Pregnancy Test FAQs

Answers to Your Questions

By the makers of FIRST RESPONSE

When a fertilized egg is implanted in the uterus, the body produces a hormone called human Chorionic Gonadatropin (hCG), and it is the presence of this hormone that at-home pregnancy tests detect. A home pregnancy test is based on the presence of hCG (human chorionic gonadatropin) in the urine. If conception occurs, the body begins to produce hCG which is released into the blood and is responsible for stopping the menstrual period. It passes into the urine where its presence is most easily detected.

The amount of pregnancy hormone increases as your pregnancy progresses. However, you can use an at-home pregnancy test as early as the first day of your missed period.

To use the FIRST RESPONSE 1-Step Pregnancy Test, just hold the stick in your urine stream for five seconds. There is no need to use first morning urine. It's so convenient, you can use the test anytime of the day. Plus, the FIRST RESPONSE 1-Step Pregnancy Test has an easy to use wide tip design and is a clear stick so that you can watch the test work and know that you performed it correctly.

A positive result may appear in as soon as one minute. (Read the instructions for complete information on how to use the test.) One line means not pregnant, two lines means pregnant . If the result is positive you are probably pregnant. See your doctor to confirm a positive result. If the result is negative, but you still do not get your period within a few days, repeat the test. You may have tested too early or miscalculated the length of your cycle. If the test comes back negative and you still haven't gotten your period, consult your physician.

These test are highly accurate, some over 99 percent accurate, such as the FIRST RESPONSE 1-Step Pregnancy Test. False positives are almost non-existent. A false negative is usually the result of taking the test too soon after conception

These tests are designed to measure the amount of hCG present on the first day of the missed period or about 15 days after possible conception.

The only substances that can affect the results of at-home pregnancy tests are medications containing the pregnancy hormone (hCG).
