Concentration (μmoles/L) of 2-aminoethyl dihydrogen phosphate and taurine in blood plasma of controls and Alzheimer’s patients calculated using the Amino Acid Analyzer method.

The lower limit of detection (LOD) for 2-aminoethyl dihydrogen phosphate using this method was 0.9 μmol/L. The lower limit of quantification (LOQ) for taurine was 10.2 μmol/L. This represents a detectable peak but one below the ability of the method to accurately quantify. When 2-aminoethyl dihydrogen phosphate was not-detectable (ND), ratios were assigned a 0.0 value.
