Chlamydia testing must be targeted at people aged under 25, the Scottish government has said.
Official statistics released by NHS Scotland show that almost three out of four cases (72%) of the sexually transmitted infection occur in the under-25 age group, but the same age group accounted for just 47% of actual chlamydia testing.
The figure for people undergoing chlamydia tests in Scotland does continue to grow, however, with a total of 267,854 tests carried out between 2008 and 2009 - up 2,991 from the previous year. The total tests figure has increased by 20% since 2005.
Public health minister Shona Robison said: “This report shows that there is still work to be done to ensure that chlamydia testing is being targeted at those most at risk - most notably, young people under 25.”
The highest proportion of samples testing positive was identified among women aged 15-19 (12%) and men aged 20-24 (14%). Figures also showed the number of positive tests was higher in men among all age groups but the majority of testing (76%) was performed on women.
The highest proportion of positive tests among women aged 15-24 was observed in the NHS Ayrshire and Arran and NHS Lanarkshire trusts (both 12%). The highest number among men aged 15-24 was observed in the NHS Borders and NHS Dumfries and Galloway trusts (both 18%).
However, the highest proportion of positive tests amongst men aged 25-49 was in the NHS Forth Valley and NHS Grampian trusts (11%).
