Evaluation of a new inhibitor test for isoamylase on Hitachi 705 analyser.

An evaluation of the Hitachi 705 analyser

Laboratory evaluation of the COBAS MIRA S random access analyser

The random access analyser COBAS MIRA S (Roche Diagnostics) was evaluated for two months. The instrument is a computer-controlled discrete analyser which can be run in a combination profile and single test mode. This instrument has special features, including an automatic cuvette segment changer, a reagent rack cooling system, an external keyboard and monitor, as well as a bar-code facility for...

Evaluation of a new procedure for isoamylase measurement by selective inhibition.

The authors have evaluated a new procedure for the estimation of pancreatic and salivary isoamylase using a new selective inhibitor reagent (Enzamyl Isoamylase, Gödecke), Germany; composition covered by patent No. P 3404876.6). Provided the conditions of the assay presented here are correctly selected, a standard curve is not necessary and the activities of both isoenzymes can be calculated by ...

A continuous method for the estimation of adenosine deaminase catalytic concentration in pleural effusions with a Hitachi 705 discrete analyser.

An assay of adenosine deaminase activity in pleural effusions is described. For the continuous determination of adenosine deaminase, the liberated ammonia is estimated by coupling the liberated NH3 with 2-oxoglutarate. The reaction is followed by the decrease of NADH absorbance at 340 nm. The assay was optimized for a Hitachi 705 analyser, with respect to pH, adenosine concentration and glutama...

Quality assessment of the Reflotron System. A blood chemistry reagent strip analyser.

We tested the accuracy of the Reflotron System by comparing results given by this system for estimations of glucose, SGOT, SGPT, cholesterol and triglycerides on patients samples which were already analysed on either an autoanalyser HITACHI 705 or manually on CLIN ICON 4010. Reflotron estimations correlated well with both Hitachi and Clinicon estimations and the strips gave reproducible results...
