Instituto Butantan | 35

Internal validated ToBI tests presented suitable to estimate the potency not only to

tetanus fraction but ALSO to diphtheria fraction in combined vaccines

Our data met all acceptance validation criteria as specificityselectivity linearity

precision (repeatability and intermediate precision) accuracy and in vitro and in vivo

concordance showed strong correlation (R=096) for both D and T components

The high relevance of these data for replacement of animal testing strongly impacts

the routine of Quality Control turning the analyses faster accurate and cheaper and

more importantly saving the lives of hundred of animals per year

Our data met all acceptance validation criteria as specificityselectivity linearity

precision (repeatability and intermediate precision) accuracy and in vitro and in vivo

concordance showed strong correlation (R=096) for both D and T components

The high relevance of these data for replacement of animal testing strongly impacts

Our data met all acceptance validation criteria as specificityselectivity linearity

Internal validated ToBI tests presented suitable to estimate the potency not only to

tetanus fraction but ALSO to diphtheria fraction in combined vaccines

Our data met all acceptance validation criteria as specificityselectivity linearity

precision (repeatability and intermediate precision) accuracy and in vitro and in vivo

concordance showed strong correlation (R=096) for both D and T components

The high relevance of these data for replacement of animal testing strongly impacts

the routine of Quality Control turning the analyses faster accurate and cheaper and

more importantly saving the lives of hundred of animals per year

Internal validated ToBI tests presented suitable to estimate the potency not only to

tetanus fraction but ALSO to diphtheria fraction in combined vaccines

Our data met all acceptance validation criteria as specificityselectivity linearity

precision (repeatability and intermediate precision) accuracy and in vitro and in vivo

concordance showed strong correlation (R=096) for both D and T components

The high relevance of these data for replacement of animal testing strongly impacts

the routine of Quality Control turning the analyses faster accurate and cheaper and

more importantly saving the lives of hundred of animals per year

Internal validated ToBI tests presented suitable to estimate the potency not only to

tetanus fraction but ALSO to diphtheria fraction in combined vaccines

Our data met all acceptance validation criteria as specificityselectivity linearity

precision (repeatability and intermediate precision) accuracy and in vitro and in vivo

concordance showed strong correlation (R=096) for both D and T components

The high relevance of these data for replacement of animal testing strongly impacts

the routine of Quality Control turning the analyses faster accurate and cheaper and

more importantly saving the lives of hundred of animals per year

Internal validated ToBI tests presented suitable to estimate the potency not only to

tetanus fraction but ALSO to diphtheria fraction in combined vaccines

Our data met all acceptance validation criteria as specificityselectivity linearity

precision (repeatability and intermediate precision) accuracy and in vitro and in vivo

concordance showed strong correlation (R=096) for both D and T components

The high relevance of these data for replacement of animal testing strongly impacts

the routine of Quality Control turning the analyses faster accurate and cheaper and

more importantly saving the lives of hundred of animals per year

Internal validated ToBI tests presented suitable to estimate the potency not only to

tetanus fraction but ALSO to diphtheria fraction in combined vaccines

Our data met all acceptance validation criteria as specificityselectivity linearity

precision (repeatability and intermediate precision) accuracy and in vitro and in vivo

concordance showed strong correlation (R=096) for both D and T components

The high relevance of these data for replacement of animal testing strongly impacts

the routine of Quality Control turning the analyses faster accurate and cheaper and

more importantly saving the lives of hundred of animals per year

Internal validated ToBI tests presented suitable to estimate the potency not only to

tetanus fraction but ALSO to diphtheria fraction in combined vaccines

Our data met all acceptance validation criteria as specificityselectivity linearity

precision (repeatability and intermediate precision) accuracy and in vitro and in vivo

concordance showed strong correlation (R=096) for both D and T components

The high relevance of these data for replacement of animal testing strongly impacts

the routine of Quality Control turning the analyses faster accurate and cheaper and

more importantly saving the lives of hundred of animals per year

Our data met all acceptance validation criteria as specificityselectivity linearity

precision (repeatability and intermediate precision) accuracy and in vitro and in vivo

concordance showed strong correlation (R=096) for both D and T components

The high relevance of these data for replacement of animal testing strongly impacts

the routine of Quality Control turning the analyses faster accurate and cheaper and

Internal validated ToBI tests presented suitable to estimate the potency not only to

Our data met all acceptance validation criteria as specificityselectivity linearity

precision (repeatability and intermediate precision) accuracy and in vitro and in vivo

concordance showed strong correlation (R=096) for both D and T components

The high relevance of these data for replacement of animal testing strongly impacts

the routine of Quality Control turning the analyses faster accurate and cheaper and

Internal validated ToBI tests presented suitable to estimate the potency not only to

tetanus fraction but ALSO to diphtheria fraction in combined vaccines

Our data met all acceptance validation criteria as specificityselectivity linearity

precision (repeatability and intermediate precision) accuracy and in vitro and in vivo

concordance showed strong correlation (R=096) for both D and T components

The high relevance of these data for replacement of animal testing strongly impacts

the routine of Quality Control turning the analyses faster accurate and cheaper and

more importantly saving the lives of hundred of animals per year
