Diagnostic tests
Uranotest Uriscreen
The quick, reliable, low-cost tool for correct decision-making in urinary tract infections.
Uranotest® Uriscreen® is a test for detecting bacteria and somatic cells in urine that makes it possible to diagnose urinary tract infections caused by catalase-positive bacteria (the main cause of urinary tract infections) and the presence of somatic cells in just 2 minutes.
In cases of suspected urinary tract infections, Uranotest® Uriscreen® enables us to decide which samples need to be sent to the laboratory for culture.
| Specs | |
|---|---|
| Purpose: | Detection of bacteria and somatic cells in urine that makes it possible to diagnose urinary tract infections |
| Sample: | Urine |
| Reading time: | Less than 2 minutes |
| Execution time: | 1 minute |
| Presentation: | Boxes with 1 test. |
| Registration Nº: | 11024 RD |
Characteristics
High sensitivity even with low bacterial counts as it detects concentrations from just 50,000 CFU/ml.
Negative (-) predictive value greater than 95% (percentage of negatives with Uranotest® Uriscreen® that truly are negative).
Result in less than 2 minutes.
Economic, which means it can be used in screening for decision-making.
No equipment needed.
Information for the veterinarian
| Catalase action (bacteria) | Expected result with Uranotest® Uriscreen® |
Visual result | Interpretation | Recomendation |
| Catalase + Staphylococcus pseudintermedius Corynebacterium diptheriae Enterobacteriaceae Escherichia coli Citrobacter spp. Enterobacter spp. Klebsiella spp. Proteus spp. Salmonella spp. Pseudomonas spp |
Positive | Foam is generated on the surface until a complete ring is formed. | There may be bacteria and/or leukocytes in the urine suggestive of urinary tract infection due to catalase-positive bacteria. | Send the sample to the laboratory for culture and antibiogram. Start treatment with a broad spectrum antibiotic effective for urinary tract infections (amoxi + clavulanic acid or cephalosporin). When you have the culture results, change the antibiotic for a more sensitive one or maintain if the current one is sufficiently sensitive. |
| Catalase – Streptococcus spp. Enterococcus spp. |
Negative, although if the sample has more than 10 leucocytes per field as a consequence of the infection, the result may also be positive. | Foam does not form on the surface or an incomplete ring of foam forms. | Catalase-positive bacteria not present in the urine. | There is no need to send the sample to the Laboratory for a culture, as the test has a negative predictive value of 95 %. |
| Screening n= 165 dogs and cats |
Sensitivity | Specificity |
| Uranotest® Uriscreen® | 89 % | 71 % |
| Determination under microscope by expert staff of the presence of abnormal urinary sediment (pyuria, bacteriuria or both) | 78 % | 90 % |
| Detection limit | 50.000 CFU/ml |
| 10 leucocytes/field |
| False negatives |
Catalase-negative bacteria Bacterial concentrations below the detection limit. |
| False positives |
Bacteria that not does not grow in cultures (Chlamydia, Trichomonas) Haematuria Presence of cells shed from the bladder or kidneys in urine Presence of tumour cells |
