Flexible:Available in up to 12 parameters
Urine Reagent Strips (URS) for Urinalysis are firm plastic strips to which several different reagent areas are affixed. Depending on the product being used, Urine Reagent Strips 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 metabolism, kidney and liver function, acid-base balance, and bacteriurea.1,2 Please refer to the outside box and bottle label for the specific test parameters of the product you are using
A urine test strip is a basic diagnostic instrument used to determine pathological changes in the urine in standard urinalysis. A standard urine test strip may comprise of up to 12 different chemical pads or reagents which react (change color) when immersed in, and then removed from, a urine sample. The test can be read between 60 and 120 seconds after dipping. Routine testing of the urine with multiparameter strips is the first step in the diagnosis of a wide range of diseases
Visual Reading Technique:
- Hold the strip up horizontally and compare the result shown on the strip with the color chart on the canister label closely and carefully. Take note of the result. For a semi-quantitative result, take down the results according to the time specified on the color chart. The pH and Protein can be read at any time within 60 seconds after dipping. For a qualitative result, the strip should be read 1-2 minute after dipping. If a positive result is obtained, repeat the test and compare with color chart at the time specified. Color changes beyond 2 minutes are of no diagnostic value.

Dip the test strip for about 1 second into the fresh urine specimen
Wipe off any excess urine on the rim of the vessel and blot the edge of the test strip on tissue paper
Testing Items: Leucocyte Nitrite Urobilinogen Protein pH Blood Specific Gravity Ketone Bilirubin Glucose
- Glucose
This test is based on a sequential enzyme reaction. First, glucose oxidase catalyzes the formation of gluconic acid and hydrogen peroxide from the oxidation of glucose. A second enzyme, peroxidase, catalyzes the reaction of hydrogen peroxide with potassium iodide chromogen to oxidize the chromogen to colors ranging from blue through greenish-brown, and brown to dark-brown.
Reactivity of the test decreases as the specific gravity and/or pH of urine increases, and may also vary with temperature. Ascorbic acid (more than 50 mg/dl) and ketone bodies (more than 40 mg/dl) may cause a false negative result for a specimen containing a small amount of glucose (100 mg/dl). However, the combinations of such ketone levels and low glucose levels are metabolically improbable..
Read the result by comparing the test fields with the color scale on the test pack after 30 to 60 seconds
VISUAL READING TECHNIQUE:
- Immerse all reagent areas in specimen and remove strip immediately.
- Run edge of strip against the rim of the container to remove excess urine.
- Compare test areas closely with colour chart on bottle label or bench reader. Record the results.
Instruction:
- Dip the test patch of a fresh strip into urine sample, or pass strip through urine stream 1 to 2 seconds only.
- Blot excess on a clean paper towel or tissue.
- Results may be compared between 1 minute od exposure to urine(colour changes occuring after 1 minute are of no diagnostic value)
Notes:
- Do not touch test areas of reagent strips.
- Do not use after expiry date
- Do not remove desiccant(s).
- Do not remove strip from the bottle until immediately before it is to be used for testing.
- Replace cap immediately and tightly after removing reagent strip.
- Store at temperature between 2°C-30°C.
- Store only in original bottle.
- The sample should not be more than 4 hours old at the time of testing.
- Collect fresh urine in a clean dry container.

FAQ
Q1: What's the method u use to do the test?
A: Colloidal Gold Method.
Q2: What's ur MOQ ?
A: Always, for strip format, the MOQ is 5000pcs. While for cassette format, MOQ is 2000pcs, same as midstream.
Q3: What's ur packing of the tests?
A: If u choose the low cost, we will suggest u the bulk packing to go. Which means 1 test in a single pouch, then 100/40 pouches in a plastic bag, 50 bags in a carton. If u need to sell in pharmacy/chain shop or some countries which have strict requirements about the packing, u can choose to pack in a box, like 100pcs in a box, or even 1 test in a single box.
Q4: What's the main differences when comparing products from different suppliers?
A: U can compare the mainly features of the test: Accuracy, Sensitivity, Specificity, and then the Price.
Q5: Some tests can be tested with serum/plasma or with whole blood, so what's the difference?
A: Well, if the specimen is whole blood, people will need buffer, lancet and alcohol swab to help the test. If they buy all the accessories, they can test very easily at home. But if the specimen is serum/plasma, it will need centrifuge to separate serum from whole blood first. This way, it's better to use at lab or hospital. And in some words, serum/plasma test will always give a more accurate results.
Q6: How can i distinguish a good test kit?
A: U can judge from the 4facts:Technical data: Such as the accuracy, specificity and sensitivity.
Pouch sealing: Tight enough. If the foil pouch is not sealed well, the humidity in circustance will destroy the reactivity of antibodies labeled on NC membrane. Shelf life will be shorten down.
Flow speed: The shorter the better?? NO!! The reaction of antibodies on NC membrane and antigens in specimen usually requires quite a while to work sufficiently. U can refer to the instruction for more accurate time.
Background: Good test usually gives clean background after running. If there are red smears in the reading window, it usually caused by bad colloidal gold technology or bad NC membrane. Sometimes, the defect caused false positive result in practice
