reagent strip การใช้

• Reagent strip manufacturers incorporate peroxide, and tetramethylbenzidine, into the blood testing area.
• Traditional reagent strip testing for protein uses the principle of the protein error of indicators to produce a visible colorimetric reaction.
• The major source of error with reagent strip occurs with highly buffered alkaline urine that overrides the acid buffer system, producing a rise in pH and a colour change unrelated to protein concentration.
• Etest is a  ready-to-use reagent strip with a predefined gradient of antibiotic for the determination of precise MIC values of a wide range of antimicrobial agents against different organism groups.
• Reagent strip tests can detect concentrations as low as five red blood cells per microliter; however, care must be taken when comparing these figures with the actual microscopic values, because the absorbent nature of the pad attracts some of urine.
• "It has been proposed that the reagent strip for leukocyte esterase designed for the testing of urine ( Combur test UX ) could be a useful tool for diagnosing spontaneous bacterial peritonitis SBP . " Braga et al . concluded that the Combur test UX urine screening test is a very sensitive and specific method for diagnosing SBP in the ascitic fluid of cirrhotic patients who have undergone paracentesis ."
