One of the prerequisites for the attainment of "accurate" analytical results in clinical chemistry is the use of suitable calibration materials and solutions. In addition, both precision and accuracy must be monitored ...

Heikkila & Cabbat (Anal. Biochem. 75, 356-362 (1976)) have proposed the autoxidation of the 6-hydroxydopamine as a method to test Superoxide dismutase activity in biological samples. This method has several advantages ...

In the present study the analytical performances of five new liquid applications on the Roche Cobas Integra were evaluated: urea and high density lipoprotein (HDL) cholesterol in serum and glucose, creatinine and inorganic ...

One hundred sera from intensive care patients, and 93 sera from endocrinological outpatients were used for a comparison between two automated assays for free triiodothyronine (Enzymun Test, and Elecsys 2010, both Boehringer ...

Reflotron®, a solid phase reagent technology capable of measuring a wide range of analytes on whole blood, plasma or serum samples has been evaluated with reference to urea, glucose, cholesterol, triacylglycerols, ...

Conjugated catecholamines in blood plasma of blood donors were determined from the difference between the total and the free catecholamines. Total catecholamines were measured after complete hydrolysis of the conjugated ...
