RESUMEN

In a study observing the effect of spirulina in the treatment of chronic arsenic poisoning quantitative estimation of arsenic in the urine of the patients was necessary. It was decided to try a modification of the arsine generator in the process. An alternative apparatus was designed following the structure of arsine generator by White (1976) using a 50-ml conical flask with rubber cork, 4-ml injection vial, two 3" long glass tubes and a glass test tube. An experiment was carried out with solutions containing known amounts of arsenic. The alternative arsine generator was tried in the estimation of arsenic content in those solutions. The results revealed that the apparatus permitted correct measurement of arsenic concentration. The alternative arsine generator was cheap easy to use and provided authentic results in estimation of arsenic concentration in the urine of patients with chronic arsenic poisoning.

RESUMEN

Since the development of the qualitative test paper for urine in 1950s, several kinds of dry-state-reagents and their automated analyzers have been developed. "Dry chemistry" has become to be called since the report on the development of quantitative test paper for serum bilirubin with reflectometer in the end of 1960s and dry chemistry has been world widely known since the presentation on the development of multilayer film reagent for serum biochemical analytes by Eastman Kodak Co at the 10th IFCC Meeting in the end of 1970s. We have reported test menu, results in external quality assessment, merits and demerits, and the future possibilities of dry chemistry.

RESUMEN

Compact dry chemistry instruments are designed for use in point-of-care-testing (POCT). These instruments have a number of advantages, including light weight, compactness, ease of operation, and the ability to provide accurate results in a short time with a very small sample volume. On the other hand, reagent costs are high compared to liquid method. Moreover, differences in accuracy have been found between dry chemistry and the liquid method in external quality assessment scheme. This report examines reagent costs and shows how the total running costs associated with dry chemistry are actually lower than those associated with the liquid method. This report also describes methods for minimizing differences in accuracy between dry chemistry and the liquid method. Use of these measures is expected to increase the effectiveness of compact dry chemistry instruments in POCT applications.
