Diabetes Screening

Diabetes screening forms an important component of a health check. Diabetes is a chronic disease that occurs either when the pancreas does not produce enough insulin or when the body cannot effectively use the insulin it produces. Insulin is a hormone that regulates blood sugar. Diabetes is growing in prevalence across the globe at an accelerated rate. It begins with few symptoms but early detection is important because there exist effective preventative strategies. According to the World Health Organisation (WHO) the global prevalence of diabetes has nearly doubled since 1980, rising from 4.7% to 8.5% in the adult population. Meanwhile, according to the Hong Kong Hospital Authority there are currently some 700,000 people with diabetes mellitus in Hong Kong, representing 10% of the total population, with that number on the increase. Meanwhile in China, according to a study published in the The Journal of the American Medical Association (JAMA), approximately 47% of the population of China was estimated to have either diabetes (11%) or prediabetes (36%), a combined level similar to that of the United States.

Fasting Blood Glucose
Blood glucose testing is used to screen individuals for raised blood sugar levels which can indicate prediabetes or diabetes. Modern lifestyles are putting the health of populations at risk with chronic conditions, such as diabetes, becoming more of a concern around the globe. According to the World Health Organisation (WHO)'s 2016 Global Report on Diabetes, an estimated 422 million adults globally were living with diabetes in 2014, compared to 108 million in 1980. The WHO said this reflected an increase in associated risk factors such as being overweight or obese.

Glycosylated Hb(HbA1c)
HbA1c

HbA1c, also referred to as haemoglobin A1c or A1c, refers to glycated haemoglobin. It develops when haemoglobin, a protein found in red blood cells (RBCs), which carries oxygen around the body, joins with glucose in the blood, becoming 'glycated'. Utilised as a diagnostic test for diabetes, measuring HbA1c offers insight into one's average blood sugar levels over a prolonged period of time. This is because RBCs in the human body survive for approximately eight to 12 weeks before renewal, meaning glycated haemoglobin measurement can be used to reflect average blood glucose levels over that duration, providing a longer-term gauge of blood glucose levels. For individuals with diabetes, measuring HbA1c is important as higher levels will indicate a greater risk of developing diabetes-related complications.
