Utilidad de la β2-transferrina y la proteína β-traza en el diagnóstico de fístula de líquido cefalorraquídeo

β2-Tr and p-βT can be used as CSF fistula markers, since both proteins have high sensitivity and specificity diagnostic values. It is concluded that, ≥ 1.14 mg/L p-βT values are indicative of CSF fistula, and values ≤ 0.64 mg/L rules it out. Values > 0.64 and < 1.14 mg/L are not conclusive, and in these cases it would be necessary to determine β2-Tr.
