^{^a}

Samples I, II, and III are the sera collected from the T. gondii-infected mice at days 3, 6, and 9, respectively.

^{^b}

Number of invalid spectra is the percentage of the correctly classified part of valid spectra.

^{^c}

Correct classified is the percentage of the correctly classified part of valid spectra.

^{^d}

The sensitivity is the percentage of the correctly classified positives.

^{^e}

The specificity is the percentage of the correctly classified negatives.
