Assessing the filtration and comparison of DTS with liquid
specimens
The results of serum tested before and after filtration were consistent.
Similar results were obtained by RBT for all levels of DTS samples when
compared with the liquid samples used to prepare DTS batch on the day of
preparation (D0). These data indicate that anti-brucella
agglutinating antibodies were not affected by filtration or air drying
during 24 hours at room temperature.
