Mumtobe ™ is >99% accurate from the day of the expected. However, some pregnant women may not have detectable amounts of pregnancy hormone in their urine on the day of the test, or may have miscalculated the first day of their period.
Your result should appear within 5 minutes. There should be at least one pink line in the Easy Read Result Window at 5 minutes to indicate that the test is completed and you have done it correctly. If not, the test is invalid. This could be due to insufficient urine on the Wide Absorbent Tip or not holding the device with the Wide Absorbent Tip pointing downward while replacing the Overcap. You should retest with another device, carefully following all directions.
