How soon can you test with first response?
The FIRST RESPONSE™ Early Result Pregnancy Test is designed to detect hCG (human chorionic gonadotropin) as early 6 days before your missed period (5 days before day of the expected period). You can use the test at any time of day. You do not have to use first morning urine.
Are First Response pregnancy tests ever wrong?
Could a positive result be wrong? Although rare, it's possible to get a positive result from a home pregnancy test when you're not actually pregnant. This is known as a false-positive.
How does the first response work?
How does the test work? The FIRST RESPONSE™ Early Result In-Stream Pregnancy Test detects in urine the hormone your body makes during pregnancy (hCG human chorionic gonadotropin).
Generally, it doesn't matter what time of day you collect a urine sample, but there are occasional exceptions. Your doctor may, for example, request a first morning sample because the urine is more concentrated and therefore it is more likely to show up any abnormalities.
