Through this experiment, trainees can master the principle of amylase determination, the preparation of reagents and learn the determination method. This experi
Creatinine in serum (plasma) reacts with alkaline picric acid to form a yellowish-red picric acid-creatinine complex, which is measured colorimetrically at 510
Urinary 17-hydroxysteroids are hormones and their metabolites secreted by the suprarenal cortex, and their excretion from urine can reflect the function of the
Urine is hydrolyzed by acid, changing bound 17-ketosteroids to free 17-ketosteroids. The latter can react with m-dinitrobenzene in alkaline solution to give a r
Uric acid in deproteinized blood filtrate is oxidized to allantoin and carbon dioxide by tungstic acid in alkaline solution, and phosphotungstic acid is reduced
The VP assay can be applied to (1) identify Enterobacter aerogenes and Escherichia coli, and (2) characterize other bacterial groups, including actinomycetes.
Most of Candida albicans need oxygen 25-30 ℃ to grow well, can also be in 37 ℃ above the growth. Colonies are cream-colored, pie-shaped and smooth. In the cor
The fecal specimen taken directly affects the accuracy of the results, usually using naturally excreted feces, specimen collection precautions are as follows:
General bacterial smear examination: select the purulent or bloody part of sputum, smear it into a uniform thin slice, perform Gram staining and microscopic exa
