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
(Streptococcus, Enterococcus)

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
