Chemical detection of leukocytes in urine by means of a new multiple test strip.

New dip-and-read test for determining leukocytes in urine.

A new reagent strip for the determination of leukocytes in urine (LEUKOSTIX; Ames) is described. The test is based on the esterase activity in leukocytes as a marker. Upon contact between the reagent matrix and a urine containing leukocytes, an amino acid ester is hydrolyzed by the esterase to its corresponding alcohol. The free alcohol then couples with a diazonium salt to produce a purple azo...

Quantitative evaluation of urinalysis test strips.

BACKGROUND Urine test strip results are generally reported in categories (i.e., ordinal scaled), but automated strip readers are now available that can report quantitative data. We investigated the possible use of these meters to complement flow cytometry of urine and compared reflectance readings with quantitative determinations of urinary glucose and microalbumin. METHODS We compared URISYS...

Frequency of extended spectrum beta lactamase producer P. aeruginosa strains isolated from burned patients of Motahari hospital, Teharan, Iran

Pseudomonas aeruginosa is an opportunistic pathogen which is naturally resistant to a large range of antibiotics like lots of Beta–Lactams (penicillins, cephalosporins and carbapenems) and may cause additional resistance after unsuccessful treatment. The understanding of beta-lactamase identification and detection in these bacteria is very valuable. In recent years a number of variety of new be...

URINE REAGENT STRIPS FOR URINALYSIS For the Semi-quantitative and qualitative detection of Glucose, Bilirubin, Ketone, Specific Gravity, Blood, pH, Protein, Urobilinogen, Nitrite, Leukocytes and Ascorbic Acid in Urine

1 TUP for Urinalysis are firm plastic strips to which several different reagent areas are affixed. Depending on the product being used, TUP provide tests for Glucose, Bilirubin, Ketone (Acetoacetic acid), Specific Gravity, Blood, pH, Protein, Urobilinogen, Nitrite, Leukocytes, and Ascorbic Acid in Urine. Test results may provide information regarding the status of carbohydrate 1,2 metabolism, k...
