Urobilinogen Urinalysis Strip
Urobilinogen Urinalysis Strip (尿胆素原尿液分析试纸) is a rapid quantitative dry chemical test kit, used to detect Urobilinogen 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 Urobilinogen Urinalysis Strip.
(Note: for urinalysis strips, the IFU is a one-for-all type, which includes introduction to all the 14 paramters.)

To carry out the assay with a Urobilinogen 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.
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 Urobilinogen Urinalysis Strip to detect the Urobilinogen in human Urine specifically. The introduction of this Color Changes under Enzyme Reaction testing principle and reagent composition is given blow.
A stable diazonium salt reacts almost immediately with urobilinogen to give a red azo dye. Colors lighter than that shown for 1mg/dL (17mol/L) constitute a normal finding. Formalin, p-aminobenzoic acid and substances known to interfere with Erlich’s reagent, such as p-aminosalicylic acid and sulfonamides, may interfere with the accuracy of test.
Reagent Composition of Urobilinogen Urinalysis Strip: 0.4% w/w p-diethylaminobenzaldehyde; 99.6% w/w nonreactive ingredients.
