We dispatch most test kits within 24 hours and by Royal Mail 1st Class post, so your test kit should arrive within a day or two. If your test has not arrived within a week or so, it may have been lost in the post (out of the 1000s of tests we deal with, this does happen now and again). If your test was free, simply return to the homepage and request a new Chlamydia test. Otherwise, please send us an email and let us know it's not arrived (please include your full name and post code, and if you have it, your tests PX, TM or SK code).

Our lab is quick to complete diagnostic testing and results are usually issued within 3-5 working days of receipt of sample. If you've not heard anything within a week or so since posting, it's possible your sample was lost in the post (of the 1000s of tests we deal with, this does happen occasionally). If your test was free, simply return to the homepage and request a new Chlamydia test. Otherwise, please send us an email and let us know you've not had results (please include your full name and post code, and if you have it, your tests PX, TM or SK code).

If you believe you may be at risk, it's advised you wait 2 weeks after potential exposure before providing a sample for testing. You can request a test and complete it later, or complete a test now and take another in a couple of weeks to be safe.

Some blood tests include a 'Cut off Index' value, which indicates the level of reaction that was detected during the test. In most cases results above 1.0 would be considered ‘reactive’/positive result, with ‘non-reactive’/negative results seeing a COI value below 1.0.

In some cases your result may be over 1.0 but only by a small margin. Officially this is considered a ‘reactive’/positive result, however due to the very high sensitivity of this test low results are often not confirmed once further testing is carried out in clinic (and are therefore a false-positive).

Many results with a COI value lower than around 10.0 do not confirm in clinic, however it is also possible these low-level results may be due to a very early infection. Therefore, it is still important you attend clinic for a full blood test to be sure of your status.
