Urea is the major end product of protein nitrogen metabolism. It is synthesized in the liver from ammonia, which is produced by amino acid deamination. The determination of blood urea nitrogen is an important index of kidney function. Impaired renal function or increased tissue protein breakdown are associated with increased urea nitrogen levels, whereas liver damage or pregnancy are associated with decreased levels.
Vet-BUN Animal Urine Reagent 1 Panel Test Strips
- Tests Urine for Blood Urea Nitrogen
- 25 or 50 Strips per Bottle
Note: A positive result from a screening is considered to be a presumptive or indeterminate result and should never be interpreted as the final result.
1. Collect urine specimen in a clean container. Mix well immediately before testing. If urine specimens are not tested within 1-hour, refrigerate specimen at 2-4°C and bring to room temperature before testing.
2. Remove strip from pouch for immediate use. Hold the plastic end of the strip and completely immerse reagent area of the strip in urine sample and remove immediately to avoid dissolving out reagent area.
3. Remove the strip slowly avoiding any spilling. Run the edge of the strip against the rim of the urine container to remove excess urine and hold strip horizontal to specimen container to avoid possible cross contamination of chemicals located in adjacent reagent pads.
4. Read results at the dictated time for each test. Beginning the moment the strip is removed from the specimen, compare reagent area to the color chart on the pouch. (Hold strip close to color block and match carefully. Do not touch the color block with the test area).
Each bottle of urinalysis reagent strips includes a color coded chart. The reactive color of each panel (square) on the test strip is compared to the corresponding color on the result chart. The concentration level range for each chemical marker is indicated below each color block on the result chart. As with all tests dealing with color intensity or color matching, it is often recommended to obtain another person's interpretation of the test result. Each of the ten reactive reagent pads on the test strip are compared to the corresponding line of color blocks on the chart. The closest color match indicates the test result. Use of reagent strips are intended as an initial indication only of elevated chemical markers and not conclusive of a specific diagnosis. Further testing and consultation is necessary to confirm the presence of specific disease or health conditions.
