LOZANO GUADARRAMA, Armando et al. Diagnóstico precoz de embarazo en la atención primaria mediante determinación cualitativa de gonadotropina coriónica humana. Rev Cubana Med Gen Integr [online]. 1998, vol.14, n.5, pp.434-439. ISSN 0864-2125.

The results of the implementation of a non-instrumental qualitative method, a clinical practical aid for the diagnosis of pregnancy at a family physician consulting room is presented. The trial consisted of detecting chorionic gonadotropin hormone in urie of amenorrheic fertile women through an enzime-based inmunoassay developed at the National Endocrinology Institute. This determination was characterization by 85 % sensitivity, 95 % specificity and 90 % accuracy (for a positive classification limit of 100 UI Hc g/L). There was 90 % coincidence between the qualitative and quantitative methods. Although this qualitative method sensitivity was lower than that required in the reviewed specialized literature, its use by family physicians is recommended as an auxiliary tool for the early diagnosis of pregnancy because of its high specificity, good correlation with the quantitative method and relative operational simplicity
