Eight aphasia screening tests were identified and evaluated across 11 studies; however, the majority had methodological flaws limiting firm conclusions about their clinical utility. "Of the four studies with an intermediate or low risk of bias, the LAST [Language Screening Test] and the ScreeLing seem to have the best diagnostic properties" (Discussion). The LAST had a sensitivity of 98% and specificity of 100%. The ScreeLing had a sensitivity of 86% and specificity of 96%.
