Simple disposable method for quantitative cultures of urine.
A disposable kit was tested as a means of detecting significant bacteriuria by quantitative culture of urine. The total error in 3,563 specimens tested by five investigators was less than 1%. The method was very effective in differentiating significant bacteriuria, i.e., more than 100,000 bacteria per ml of urine from uninfected urine. In specimens from patients with urinary tract abnormalities...

متن کاملSimple method for determination of thiocyanate in urine.
BACKGROUND It would be useful to develop a simple kit method for determination of thiocyanate in urine, which could be used to monitor cyanide overload in cassava-consuming populations. METHODS The method was based on the quantitative oxidation of thiocyanate in acid permanganate at room temperature in a closed vial with liberation of HCN, which reacted with a picrate paper. For semiquantitat...
متن کاملMethod for quantitative measurement of xanthurenic acid in urine.
A method is reported for determining urinary xanthenuric acid (XA), a meta. bolite of tryptophan. XA is extracted from urine with isobutanol (2.methyl. 1.propanol), transferred to ammonium hydroxide, and separated from other urinary metabolites on thin.Iayer cellulose plates with use of 0.2 acetate buffer, mol/liter, pH 5.4. The XA is measured spectrophotometrically after diazotization with 2-c...
متن کاملNew colorimetric method for quantitative determination of protein in urine.
Total urinary protein is rapidly precipitated at room temperature by tannic acid. The tannic acid/protein precipitate, dissolved in aqueous triethanolamine/ferric chloride solution, gives a purple-violet color of high absorptivity. Absorbance at 510 nm is linearly related to concentration from 0.05 to 1.50 A for a protein content of 0.05 to 1.50 g/liter, and less than 5 mg/liter can be detected...
