Bilirubin Urinalysis Strip

Bilirubin Urinalysis Strip (胆红素尿液分析试纸) is a rapid quantitative dry chemical test kit, used to detect Bilirubin in human Urine specimen, based on the principle of Colorimetric method: Color Changes under Enzyme Reaction.

Please refer to the Instruction for Use (IFU) of the Bilirubin Urinalysis Strip.

(Note: for urinalysis strips, the IFU is a one-for-all type, which includes introduction to all the 14 paramters.)

  • Instruction For Use (IFU).

To carry out the assay with a Bilirubin Urinalysis Strip, Urine should be collected according to the instructions given in the Instruction For Use included in the test kit. After collecting, it is preferable to perform the testing as early as possible; if not viable, the specimen should be stored properly. A general introduction about the collection, and storage of the specimens is given below.

Urine Collection

A urine specimen must be collected in a clean and dry container.

For hormone test such as HCG prenancy test, the first urine specimen in the morning is preferred since it generally contains the highest concentration of hormone, although urine specimens collected at any time of the day may be used.

Urine specimens exhibiting visible particles should be centrifuged, filtered, or allowed to settle to obtain clear specimen for testing.

Urine Storage Condition

Urine specimens may be stored at 2-8°C for up to 48 hours prior to testing. For long-term storage, specimens may be frozen and stored below -20°C.

Frozen specimens should be thawed and mixed before testing.

Color Changes under Enzyme Reaction method is used in this Bilirubin Urinalysis Strip to detect the Bilirubin in human Urine specifically. The introduction of this Color Changes under Enzyme Reaction testing principle and reagent composition is given blow.

Color Changes under Enzyme Reaction

The test for bilirubin is based on the coupling of bilirubin with a diazonium salt. Normally no bilirubin is detected in the urine even by the most sensitive methods. The slightest discoloration of the reagent area constitutes a positive result, meaning pathologic damage may have happened.

False negative result may be produced by metabolites of drugs that give a color at low pH or by ascorbic acid concentrations in excess of 1.4mmol/L. Indoxyl sulfate may also interfere with the interpretation of a negative or positive bilirubin reading.

Reagent Composition of Urine Bilirubin Urinalysis Strip: 0.4% w/w p-chloroaniline diazonium salt; 50% w/w buffer; 49.6% w/w nonreactive ingredients.
