What Are Fertility Tests?
Fertility tests help identify key biological markers that influence the ability to conceive.
At RapidTest.co, our at-home fertility range includes quick, lab-free tests designed for both men and women — helping couples understand their reproductive health before seeking clinical support.
These tests are ideal for couples trying to conceive, monitoring hormone cycles, or simply checking reproductive wellness from the privacy of home.
HOW THE TEST WORKS
The Syphilis Rapid Test detects antibodies produced in response to Treponema pallidum infection. It uses lateral-flow technology (similar to a COVID or pregnancy test) and delivers results in 15 minutes.
Step-by-Step:
1️⃣ Collect a small blood sample using the sterile lancet provided.
2️⃣ Add a few drops of blood and buffer solution to the test cassette.
3️⃣ Wait 15 minutes and read your result.
Results:
- One line at “C” = Negative (no antibodies detected)
- Two lines (C + T) = Positive (antibodies detected)
- No line/invalid = Repeat with a new kit
