Different methods of screening for Chlamydia have been analysed by research conducted by the University of Bristol.
The study found that partner notification is an "essential component" of managing sexually transmitted infections.
Indeed, around two-thirds of sexual partners of patients who test positive for Chlamydia are found to be infected themselves.
Sixty-five per cent of male partners of Chlamydia positive women were found to be infected in 2008-09.
This compares to just six per cent of men who tested positive for Chlamydia in primary screening procedures.
Dr Katy Turner commented: "Partner notification is an underused but highly effective strategy for increasing treatment of infected individuals, particularly men.
"Partners of infected patients may be up to ten times more likely to be infected than individuals identified through primary screening."
She added that increasing the efficacy of partner notification systems would be likely to improve the number of people successfully treated for the disease without substantially increasing the costs involved.
