CTAD: data request form


The Chlamydia Testing Activity Dataset (CTAD) is comprised of all chlamydia (NAATs) tests for all ages (with the exception of conjunctival samples), from all venues and for all reasons.

CTAD enables unified, comprehensive reporting of all chlamydia data, to effectively monitor the impact of the National Chlamydia Screening Programme (NCSP) through estimation of population screening coverage, proportion of all tests that are positive and diagnosis rates.

Due to a large number of requests for CTAD data, we ask that you allow at least 2 working weeks for the data to be compiled.

Completed forms should be emailed to:
