We are pleased to inform you that we have obtained a Gen-Probe TIGRIS DTS Automated Analyser and that we are switching all our Chlamydia and N Gonorrhoeae NAAT testing to the Gen-Probe APTIMA COMBO 2 Assay, this will take effect from Monday 22nd February 2010. This change will allow us to streamline our Chlamydia testing service by increasing our sample throughput, with increased specificity and with no loss in sensitivity. The APTIMA Combo 2 assay will detect all strains of Chlamydia trachomatis including the new variant (nv(CT)) and will specifically detect Neisseria gonorrhoeae rather than Neisseria species. It will also reduce the number of equivocal and inhibitory results.
It will however, involve a change in transport media for the swab and urine specimens. The sampling kits will be provided in the usual manner via requisition forms and they require the swabs/ urine samples to be placed directly in the sample transport media (lysis buffer). This immediately lyses the sample thus stabilizing the specimens and negating the necessity of rapid transport of the sample to the laboratory. Any samples requiring C. trachomatis / N. gonorrhoeae testing NOT received in the appropriate lysis buffer after 1st March will NOT be tested. You will still require a stock of Red Topped Transport Media for any samples requiring Genital Herpes or Genital Ulcer Screening.
