If you receive a negative test but think you are pregnant, then there may be a mistake. To minimize test failure, follow the rules:
• Prepare clean, dry containers for collecting urine.
• Do not immerse the test deeper than the control line and do not keep it in urine for longer than the specified time.
• Do the test immediately after waking up.
• During the day, a woman drinks a lot of fluid, so the urine is diluted and the level of human chorionic gonadotropin decreases.
• Poor quality test.
• A negative result may occur if the test does not have a good litmus test. Low sensitivity of the device may prevent the test from detecting human chorionic gonadotropin in the first days after fertilization.
• Improper storage and expired expiration dates increase the possibility of test failure.
• A poor-quality test may not show pregnancy.
