Before you start

You will need:

  • Your Chlamydia test kit

  • A timer or your phone

Before starting:

  • Check the expiry date.
  • Do not use the test if the package is damaged or already open.

  • Squeeze the tube around the swab and rotate the swab 15 times.
  • Leave it for 1 minute.
  • Squeeze the swab against the side of the tube.
  • Remove and throw the swab away.
  • Attach the dropper tip to the tube.

Step 3 — Take the test

Your result (as shown in the instructions)

This is a customer-generated record of a self-reported screening result. It is not a clinically verified medical certificate or a formal diagnosis. CareFree Kits has not seen or verified this result.

What to do next

For a positive result, contact a GP or sexual health service for assessment, appropriate confirmation and treatment. A negative result does not rule out infection: seek advice if you have symptoms, an exposure or ongoing concerns. No control line means invalid; use a new kit and seek advice about persistent uncertainty.

This kit does not screen for every STI or establish that other sample sites are infection-free. An inadequate sample or testing too soon may give a negative result despite infection. Do not substitute a throat, rectal or urine sample for the stated method.

Important information

Important information for all tests.

  • Check the expiry date. Never use a test that is expired, damaged or already open.
  • Only use the swab and items supplied with your kit.
  • Use a timer and read your result at the exact time stated. Never read it late.
  • No C line means the test is invalid. Repeat it with a new kit.
  • A negative result does not always rule out infection. Testing too soon, or collecting too little sample, can affect it.
  • A positive or reactive result should always be followed up with a healthcare professional.
  • Still have symptoms or worried about a recent exposure? Speak to a healthcare professional, even if your result is negative.
  • Not sure what your result shows? Do not guess. Repeat the test with a new kit or speak to a healthcare professional.
  • Keep test kits away from children and pets, and dispose of used items safely.
