The FSHS invites those who have been tested for chlamydia for re-testing


Apr 23, 2019

Since late February 2019, about 100 cases of genital chlamydia have been diagnosed in Finland in which the patients’ specimens have been negative with one assay used to test for chlamydia and gonorrhoea but positive with another test for chlamydia. Only a small proportion of persons tested have received an erroneous result.

FSHS will contact patients for re-testing

The situation has been caused by problems with one chlamydia test which is widely used in Finland. This test and remote test have also been used by the FSHS. FSHS patients who may have received an erroneous test result between 1 October 2018 and 28 February 2019 will be invited for re-testing. There are a total of 23 such patients.

  • The FSHS will contact 23 patients personally right away and give them instructions for re-testing.
  • The FSHS has started contacting patients for re-testing on 23 April and will contact all of them during this week.  
  • If you have been tested for chlamydia during the period mentioned above and you are not contacted by the FSHS, you have no reason whatsoever to worry.
  • All chlamydia specimens tested from 1 March 2019 onwards have been tested using a different method, and these test results are reliable.
  • If a specimen was given before 1 October 2018, re-testing is not necessary as chlamydia infections are common and the risk of re-infection is high.

Further information is available from your local FSHS unit.
