What else do I need to know about home pregnancy tests?

Other tips to follow when taking an at-home pregnancy test include:

  • If you wish to use a home pregnancy test kit, be sure to check the expiration date on the package before purchasing. If the kit is past its expiration date, the test results may not be accurate.
  • Use your first morning urine when possible, when hCG levels are most concentrated.
  • Do not drink excessive amounts of fluids before the test to increase the volume of urine. This could dilute the hCG levels.
  • Read the directions included in the test thoroughly before starting the test, and follow every step precisely.
  • Some fertility drugs may interfere with the test results. Most other over-the-counter and prescription drugs, such as birth control pills and antibiotics, should not affect the results of a home pregnancy test. Check the package labeling for additional information.

Always see your doctor if you are unsure about your home pregnancy test results, and always see your doctor if you experience any unusual pain after missing a period—even if your pregnancy test was negative.
