Rapid Test Kit

Rapid test kits are designed for use where a preliminary screening test result is required and are especially useful in resource-limited settings.
• High quality
• Quick (10 minutes to 2 hours) and easy to perform .
• Tests based on agglutination, immuno-chromatographic, immuno-dot, and/or immuno-filtration techniques.
• Are suitable for individual or a limited number of samples, and require little or no additional equipment, which make them more economical than ELISAs in fully equipped laboratories.
• Possibility to store at room temperature for an extended period of time.

• Same-day results provide timely treatment possibility.

[Test Principle]

Urobilinogen:Urobilinogen with diazonium salt produce red violet dyes in strong acid medium.

Bilirubin:The direct bilirubin with dichlorobenzene diazonium produce azo dyes in acid medium.

Ketone:The acetoacetic acid and sodium nitroprusside cause reaction in alkaline medium,which produces red violet compound.

Blood:Hemoglobin acts as peroxidase. It can cause peroxidase release neo-ecotypes oxide (O).(O) oxidizes the indicator and make the color change subsequently.

Protein:It is based on a specific pH indicator attracted by cation on protein molecule,the indicator further ionized and make the color change.This phenomenon is called protein-error-of -indicator principle.

Nitrite:Nitrite and aromatic amine are diazotized to form a diazonium compound.The diazonium compound reacts with tetrahydrobenzo(h)quinolin 3-phenol produce the red azo dye.

Leukocyte:Pyrrole amino acid ester produce free phenol under the hydrolysis of esterase in neutrophile granulocyte,the free phenol couple with phenyl diazonium salt produce purple azo dyes.

Glucose:The glucose oxidized by glucose oxidase catalyzes the formation of glucuronic acid and peroxide hydrogen.Peroxide hydrogen releases neo-ecotypes oxide(O)under the function of peroxidase.(O)oxidizes tetramethyl benzidine,  which make the color change.

Specific Gravity:Methyl vinyl ether and maleic acid copolymer is weak acid (-COOH) exchanger,the M+ cation (the major is Na+) in urine reacts with the exchanger and release hydrogen ion,hydrogen ion reacts with indicator produce color change.

pH:The method of pH indicator is applied.

Ascorbic Acid:Ascorbic acid deoxidizes the 2.6-dichlorphenolindophenol dye into colorless in alkaline medium.

Microalbumin:Sulfone phthalein dye has high sensitivity to microalbumin by the method of protein error.

Creatinine:Creatinine with 3,5-Dinitrobenoic acid produce violet compound in alkaline medium. 

Calcium:Calcium ion reacts with methyl bromothymol blue produce color change in alkaline medium.
