Evaluation of infusion sets by biological and chemical testing

Some of the biological and chemical tests used in toxicological evaluation of synthetic polymers were correlated. The individual tests (sperm cell motility, tissue culture inhibition, intracutaneous test, optical absorption at 220-360 nm, reducing impurities) did not mutually correspond. The final estimation of the tested device is assessed as a sum of these units. Therefore, it is necessary to evaluate the results of the individual tests in arbitrary units.
