Agreement between Observers for Pap smear and Visual Inspection Tests in Florianópolis, Southern Brazil

Evandro Russo, Emil Kupek, Joyce Tarnowsky Leitão, João Péricles da Silva Júnior & Maria Beatriz Cacese Shiozawa · Journal of Advances in Medical and Pharmaceutical Sciences · 2015

Aim: Despite well established validity and reliability of Pap test, a significant proportion of false negative test results still remains and is partially due to the lack of agreement between observers.  Visual inspection tests (VIT) share this difficulty but their results are im...

Statistical Analysis of Monocyte Monolayer Assay Validation in Brazilian Blood Donors

Jéssica Hanser Nunes Kahl, Everaldo José Schorner & Emil Kupek · International Blood Research & Reviews · 2023

Aims: To validate the monocyte monolayer assay (MMA) technique concerning its suitability for blood donor screening and its cost per test performed. The MMA is an in vitro simulation of the behavior of the antibodies, demonstrating the reactions that would occur in the endothelia...
