| These interpretations are based on the largely varying cut off values reported by the participants [Table 3]. The data of the five surveys [Mai11-Nov.13] are reported and explained in the commentaries documented in the website of INSTAND (www.instand-ev.de). With the reference to different combinations of the analytes Aß1-42 amyloid peptide and total Tau protein concentrations we summarize the variation of results reported by the individual laboratories according to their individual cut off values [reference range]. |
