Thousands of 18-24 year olds from Essex will receive Chlamydia self-testing kits in the post.
Around 24,000 kits will be distributed by NHS South East Essex in a bid to lower the number of people contracting the most common sexually transmitted infection (STI).
Specific tests for males and females will be sent out in discreet packaging, with clear instructions, laboratory contact information and details of NHS sexual health services. An extra 5,000 residents between the ages of 22 and 24 in the area will also be sent letters containing more information about STI tests.
Dr Andrea Atherton, director of public health at NHS South East Essex, said: "I hope the young people who receive the kit will use it.
"The benefits of taking this quick simple test far outweigh the risk of having an untreated infection which can cause chronic pain and may lead to infertility."
Youngsters in south east Essex who want a Chlamydia testing kit can get one by texting "Kit" followed by their name, age and address to 80010, or they can visit the website: www.ruclear.nhs.uk.
