and certain ethnic groups (Asian, Central American, etc.) (1; 2; 63). The screening<br />

frequency is determined by consensus; screening is recommended every three<br />

years for people over 45 years old and on an annual basis for patients suffering<br />

from other risk factors (hypertension, dyslipidemia, pre-diabetic stages, etc.) (64).<br />

As regards the screening technique, the reviews and Clinical Practice<br />

Guidelines analysed recommend fasting plasma glucose. Determination through<br />

capillary glucose in total blood, could simplify the diagnosis. Although there are<br />

multiple studies published on capillary glucose on the diagnosis of diabetes (65-<br />

68), none of them complies with the quality standards demanded for a study on<br />

diagnostic tests, therefore the located evidence does allow its recommendation for<br />

this purpose.<br />

An annual diabetes screening is recommended through fasting plasma glucosein the population<br />

at risk, defined by hypertension, hyperlidemia, obesity, gestational diabetes or obstetric<br />

pathology (macrosomia, repeated miscarriages, malformations), Impaired Fasing<br />

Glucose and Impaired Glucose Tolerance at any age; and every three years in patients<br />

aged 45 or over, within a cardiovascular preventive structured program.<br />

Capillary glucose in total blood cannot be recommended as a diagnostic test in the population<br />

groups at risk.<br />
