Abstract
SANCHEZ FRENES, Pedro et al. Is the pre-donation lipemia test useful for blood donor selection?. Rev Cubana Hematol Inmunol Hemoter [online]. 2014, vol.30, n.3, pp. 265-272. ISSN 0864-0289.
In addition to the Cuban regulated tests for donor selection, the Cienfuegos provincial blood bank uses a predonation lipemia test. The present study evaluates the diagnostic efficacy of this test. Two visual estimates of plasma for turbidity were performed: the first before donation and the second one to the plasma unit obtained from the whole blood collected, this one used as a reference test for this study. Both observations were made by the same observer following an established protocol. As part of the study, the presence of a positive test predonation lipemia was not cause for excluding donors. Diagnostic sensitivity and specificity, positive predictive value (PPV) and negative predictive value (NPV) and efficiency of the test within a confidence interval of 95 % were calculated. We obtained 98,4 % specificity, 80 % sensitivity and 66,6 % positive predictive value and 99,0 % negative predictive value, with 95,7 % diagnostic accuracy. The test is useful for the selection of blood donors and we recommended its use in all blood collection services having technical conditions for its fulfillment.
