Content: Do a morning test: A woman should use her first morning urine to do the test because it has more hCG in it. Urine becomes more dilute as a person drinks more liquids during the day, Helgeson said. Although not all tests recommend using the first morning urine, this sample will contain the highest levels of pregnancy hormone. Retesting may be needed: If a woman suspects she is pregnant and gets a negative test result, she should repeat the test several days to a week later because hCG levels rise rapidly during early pregnancy. Timing matters: Testing too close to conception or too early after a missed period may produce incorrect results because the placenta has not yet had time to produce enough hCG to be detected by the test. Seek additional help: If a woman has questions about the product, its correct use or whether studies have been done on the test's accuracy, she can get in touch with the manufacturer by phone or through the online contact information listed on the box.
