All adults aged 40 and above should have a risk assessment for type 2 diabetes, according to the healthcare watchdog.
The National Institute for Health and Clinical Excellence (NICE) has also recommended that people aged 25 and above of South Asian, Chinese, African-Caribbean or Black African descent, who are at a higher risk, should also perform a test.
People can be assessed at their GP surgery or community pharmacy but they can also perform self assessments online.
Nice said the new recommendations will help to identify people at high risk so they can be offered advice to help them prevent or delay the condition.
The body also recommends that health and community services, workplaces, job centres, faith centres, libraries and shops should offer risk assessments so they are more widely available.
If someone is identified as high risk they should contact their GP for a blood test to confirm the level of risk, the new NICE guidelines suggest.
NICE also recommends that people who are identified as high risk should be given an “evidence-based, intensive lifestyle-change programme” to prevent or delay the onset of type 2 diabetes.
Diabetes currently affects almost three million people in the UK, of which about 90% will have type 2 diabetes.
Birmingham Community Healthcare Trust diabetes nurse consultant Jill Hill added: “As a diabetes nurse, I have seen first-hand how the condition can affect a person’s life.
“People may not be aware that diabetes is the most common cause of visual impairment and blindness, kidney failure and non-traumatic lower limb amputations.
“This guidance focuses on risk assessment and providing those at high risk with evidence-based, effective interventions that can delay or prevent this condition.”
