Spot-test identification and rapid quantitative sequential analys is of dipyrone

Semi-quantitative "spot-test" of cyanide.

A selective, sensitive, rapid and simple-handling analytical method for the determination of cyanide at low detection limits in surface and underground water, soil and industrial waste samples was developed. The method is based on a reaction, proposed by Guilbault and Kramer, where free cyanide reacts with p-nitrobenzaldehyde to form an intermediate cyanohydrin, which reacts with o-dinitrobenze...

Quantitative Dengue Test: Is it Practical for Clinical Practice?

Modified Spot CAMP Test: A rapid, inexpensive and accurate method for identification of group B streptococci.

A rapid modified spot CAMP test using 183 clinical isolates of beta haemolytic streptococci was compared with the standard CAMP test described by Christie et al. The scheme of biochemical identification and serological confirmation was taken as reference method. The sensitivity of both tests was 100%, and the specificity of the rapid and standard tests was 96.8% and 88.9% respectively. The modi...

Rapid Quantitative Turbidimetric Spot Test Analysis of Potassium In Blood Serum

Um método micro-analítico, “spot-test” foi desenvolvido para a determinação de potássio em soro sangüíneo. A precipitação de potássio é feita em meio alcalino com o reagente tetrafenilborato de sódio. A medida turbidimétrica é realizada diretamente com esta solução, sem a necessidade de diluição, usando uma micro-cela turbidimétrica desenvolvida neste trabalho. O soro sangüíneo é misturado com ...

the rapid camp test for identification of

alpha toxin derived from clostridium perfringens was used for diagnosis of streptococcus agalactiae (st.agalactiae) by rapid and spot camp tests. the selected cl.perfringens strain was cultured in optimized conditions; the supernatant of culture was concentrated by ultra filter and purified by deae cellulose chromatography. the efficacy of both purified and crude α-toxins were examined by rapid...
