Table 2. Comparison of the malondialdehyde concentrations obtained with the thiobarbituric acid (TBA) assay and the 2-aminoacridone (2-AA) assay on two samples of pooled tears obtained from 5 (Pool 1) or 6 (Pool 2) healthy subjects.

  TBA assay 2-AA assay TBA/2-AA* Ratio free MDA/ total MDA
Pool number MDA [nM] Free MDA [nM] Total MDA [nM] [%] [%]
Pool 1 337±42 (n=4) 34±11 (n=4) 5′420±250 (n=3) 6.2 0.63
Pool 2 524±190 (n=4) 47±7 (n=5) 6’554±840 (n=7) 8.0 0.72

The number of repetitions (n) of the MDA measurement is indicated in brackets. MDA=malondialdehyde; TBA=thiobarbituric acid; 2-AA=2-aminoacridone * considering the total MDA measured with the 2-AA technique
