Diabetes mellitus is a non-communicable disease, increasing its prevalence day by day becoming a heavy burden to the individual and to the country. It carries high morbidity and mortality mostly at later stages. Most patients are asymptomatic at early stage of the disease. Most clinicians ask for fasting blood sugar or random blood sugar levels as a screening method for diabetes. Taking blood samples carry risk of the procedure and it will cause pain to the patients which they hesitate to do. Study on variations of wave form in diabetic patients aged 50-65 years was done. Using non-invasive PPG signal, blood samples were taken at finger tip. Nine patients with isolated diabetes (i.e. Non-hypertensive, non-dyslipidaemic, no ischaemic heart disease) who were on regular antidiabetic treatment and 11 non-diabetic (with neither hypertension, dyslipidaemia nor ischaemic heart disease) aged 50-65 years females were selected from NHSL (National Hospital of Sri Lanka) and Sri Jayawardanapura Hospital. They were interviewed and their blood flow was recorded using PPG signal for 5 minute duration connecting the probe to the index finger. Standard indices of wave form were calculated during data analysis. Out of 9 diabetic patients, 8 were identified as diabetics by calculating the standard indices of the pulse wave form. Our conclusion is that calculated indices of PPG signal has a sensitivity of over 88% in screening of type II diabetes in females aged 50-65 years.
