Cutoff Sensitivity (%) Specificity (%) PPV (%)
C22:0  < 105 µmol/l 0.0 92.4 0.0
C24:0  < 92 µmol/l 24.2 94.1 50.0
C26:0  < 1.2 µmol/l 81.8 94.1 82.1
ratio C24:0/C22:0  < 1.0 97.0 94.1 83.8
ratio C26:0/C22:0  < 0.02 90.9 95.0 80.6

All values equal or above the mentioned values are considered to be abnormal.

PPV: positive predictive value.
