We discussed in our diabetes primer article the health impact of diabetes, its symptoms, and the different types of diabetes. In this article, we will discuss in greater detail about diabetes diagnosis in Singapore.
Three Types Of Blood Tests For Diabetes Diagnosis
You can have diabetes diagnosis done at GPs and hospitals. When you go for diabetes screening, one of three types of blood tests may be done to determine if you have diabetes.
Fasting Blood Glucose Test
Fasting blood glucose tests are done after about 8 hours of fasting (typically overnight, so you can have breakfast after the test). A fasting blood sugar of 3.3 to 7.0 mmol/L is normal. If it is higher than that, it is indicative of diabetes. This test is the preferred test for diagnosis of diabetes as it is easily done and is supported by strong scientific evidence. This test is suitable for diagnosing both diabetes and pre-diabetes.
Random / Casual Blood Glucose Test
This test involves taking a random blood glucose sample similar to Fast Blood Glucose Test, but without fasting. If the result is 11.1 mmol/L or greater, you might have diabetes. This test takes the least amount of time for the patient but is not as reliable as Fasting test. It is also not suitable for detecting pre-diabetes. Where possible, you should opt for Fasting test instead.
Oral Glucose Tolerance Test (OGTT)
OGTT requires 8 hours of fasting as well. A sample of fasting blood is taken, after which you will be required to drink a small amount of a sugary drink. Another blood sample is taken 2 hours after the drink. A fasting blood sugar level of above 7.0 mmol/L or a level more than 11.1 mmol/L after the drink is indicative of diabetes. OGTT is thus a more complex testing method, but is reliable and is suitable for diagnosing both diabetes and pre-diabetes.
Cost Of Diabetes Diagnosis In Singapore
Based on a report by CNA, basic health screening (which includes testing for diabetes) at private clinics typically cost around $50 and above, while those at hospitals may cost from $80 and above.
However, Singaporeans aged 40 years and above may enjoy subsidised diabetes screening at $5 or less under the national Screen for Life programme. Singaporeans aged from 18 to 39 years old at ‘Higher Risk’ for diabetes may also be eligible for subsidised screening – take an assessment using Health Promotion Board’s assessment tool here.
