Pyrogallol Red

Product name:Pyrogallol Red

Product description:The measurement of protein concentration in the cerebrospinal fluid is a basic analytical method in neurology. In this study, a pyrogallol red technique using a human albumin calibrator previously validated in human medicine was tested for canine samples, and the results were compared with those obtained using urine test strips. Pyrogallol red significantly (P<0·05) but moderately underestimated purified dog albumin and globulins. The imprecision of the technique was low: intra- and between-series coefficients of variation were 1·6 and 4·3 per cent at protein concentrations of about 0·3 g/litre. Over 49 samples, there was good agreement between the pyrogallol red and test strip results (r=0·63), especially for low and high protein concentrations, but misclassifications were observed with‘+’test strip readings.
