From: Effects of certain pre-analytical factors on the performance of plasma phospho-tau217
The accuracy of plasma p-tau217 to identify individuals with abnormal CSF Aβ42/Aβ40 or p-tau217 status. ROC curve analyses for identifying abnormal a CSF Aβ42/Aβ40 status and b CSF p-tau 217 status (see Tables 3 and 5 for sensitivity and specificity measures). Abbreviations: AUC, area under the curve; C, centrifugation; NC, non-centrifugation; ROC, receiver operating characteristic; RT, room temperature
