A study on validity and usefulness of various tests for mass screening of diabetes mellitus
Joung Soon Kim, Soon Gyu Yun
Abstract
This study was carried out to determine validity and usefulness of various tests for mass screening of diabetes mellitus prior to the national diabetes mellitus prevalence survey. The tests studied include capillary blood sugar value measured by Glucometer II in comparison with verified Oxidase method, validity of fasting blood sugar and 2hrs. postprandial blood sugar and urine sugar test by uristix(Ames Co.),and usefulness of some risk factors as a screening tool. The results obtained are as follows : 1. Capillary blood sugar values measured by Glucometer II showed 0.872 correlation coefficient with the values measured by oxidase method : the Glucometer II measurement of blood sugar appeared to be very useful, particularly in a field survey, owing to its high validity and its technical simplicity. 2. The sensitivity and the specificity of fasting blood sugar based on WHO diagnostic criteria (FBS : ≥ 120 mg/dl and 2hr. PPBS ≥ 200mg/dl) was 100% and 93.3% respectively. On the other hand these of 2hr. PPBS were all 100%. Therefore it would be most valid and economic for diabetes mass survey if ≥ 120mg/dl FBS is used for screening and then confirmed by ≥ 200mg/dl 2hr. PPBS. 3. Urine sugar test was neither sensitive nor specific enough to be useful in diabetes screening. 4. Risk factors such as family history of diabetes mellitus, overweight or obesity and sex did not show strong association with the presence of diabetes mellitus so as to discriminate or select out diabetics from nondiabetic normal population. 5. More deterministic conclusion may be expected when over 20,000 subjects studied are analyzed.
