Effect of training on the performance of blood glucose monitoring using a reagent strip (Glucoprofil).

A relatively simple, new test-strip for blood-glucose monitoring, the Glucoprofil strip with a reaction-zone of film-foil, was evaluated by testing 100 different blood glucose concentrations between 2.1 and 29.7 mmol/l. The results were obtained visually before and after training to read the color changes of the strip according to the scale on the strip-container. Plasma glucose measurements with the Beckman Glucose-Analyzer were used for reference. The results show that the Glucoprofil-strip readings correlated well with the reference method (r = 0.97), thorough training provided. The mean deviation of the strip results was less than 1 mmol/l. Similar results were obtained using another blood glucose strip, the Haemoglukotest 20-800 R. Our study indicates that the performance of the Glucoprofil strip is satisfactory, and hence the strip may be useful for clinical purposes. Consistent with previous reports we could demonstrate that training improved the reading results of the Glucoprofil strip.

Urine specific gravity measurements: comparison of a new reagent strip method with existing methodologies, as applied to the water concentration/dilution tests.

A study was carried out to compare a new, unique chemical strip test for the measurement of urine specific gravity with the traditional methods of hydrometry and refractometry, during water concentration/dilution tests in 12 normal subjects. The pattern of specific gravity results during these serial measurements was virtually identical for the strip and for the comparative methods. Comparison of the strip results with those obtained by both hydrometry and refractometry produced acceptable linear regression data. In addition, a close relationship was demonstrated between the strip specific gravity and urine osmolality. The findings show that the strip method is an acceptable alternative to traditional methods as an indicator of urine concentration.

Characteristics of binding between reagent-strip indicators and urinary proteins.

We describe the binding characteristics of two indicator dyes that are widely used in commercial "dip-stick" indicators for protein in urine. Binding was studied by both gel filtration chromatography and by spectrophotometric titrations. The results demonstrate that the well-known lack of sensitivity of these strips to proteins other than albumin relates to the number and affinity of binding sites on these proteins as compared to albumin. The data suggest that these test strips can screen more effectively for albuminuria than for other proteinurias.
