From 1 September 2017 , all Singaporeans aged 40 and above can get tested for diabetes, cholesterol, blood pressure and cervical cancer, for $5 at most, at the 950 Community Health Assist Scheme (Chas) clinics across the island. Those older than 50 can also get tested for colorectal cancer at no extra cost. Without the subsidy, these tests would cost around $100.
Pioneers can get tested for free, while Chas card holders will pay $2. Younger Singaporeans, aged between 18 and 39, are also eligible for testing if they are at risk of diabetes.
Subsidised tests can be done every three years, and the rates cover both the screening and a consultation if required.
