First Response tests either show a digital YES+/NO- readout or use color indicator lines. In line-based tests, two lines indicate pregnant and one line indicates not pregnant; digital models display a clear YES or NO result.
First Response pregnancy tests use urine as the sample; some kits include an EasyCup urine collection cup with a built-in test strip.
Digital First Response tests include a ‘test in progress’ or control indicator that shows the test is running and ready; non-digital strip tests display a control line to confirm the test ran correctly. After the test runs, the result appears as a digital YES/NO or as color indicator lines.
First Response tests are compact and individually wrapped for discreet, on-the-go use, with small test sticks and strips designed for privacy.
Some First Response digital tests list included non-universal lithium batteries (examples show 1 or 2 non-universal lithium); many test sticks and strips do not require batteries.
