When to take it: The test can detect if you are pregnant up to five days before a missed period.
Result time: Test results are achieved in three minutes.
Medical Interactions: Fertility drugs containing hCG can affect the test results. Alcohol, painkillers, antibiotics, or the contraceptive pill should not affect the test results.
