Performance

Urine analysis is the most common clinical microbial test.

For instance, in France in 2007, out of 10 million bacteriology tests carried out, 6 million (60 %) were urinanalyses. Thus, any workload reduction related to this analysis will dramatically improve the efficiency of the laboratory.

Intended Use


CHROMagar™ Orientation is a non-selective chromogenic culture medium intended for use in the qualitative direct detection, differentiation and presumptive identification of uropathogens to aid in the diagnosis of urine tract infections. The test is performed with urine samples. Results can be interpreted after 18-24 h of aerobic incubation at 35-37 °C.


Concomitant cultures are necessary to recover organisms for further microbiological testing or epidemiological typing. A lack of growth or the absence of colonies on CHROMagar™ Orientation does not preclude the presence of bacteria. CHROMagar™ Orientation is not intended to diagnose infection nor to guide nor monitor treatment for infections.


CHROMagar™ Orientation can also be used with veterinary samples.

1. Instant palette of colours to obtain a large spectrum of species differentiation: 

CHROMagar™ Orientation has several advantages over traditional media :

- allows in most cases full differentiation of the pathogens,

- allows for reliable detection semi-quantitative and presumptive identification of urinary tract pathogens,

- easier recognition of mixed growth,

- provides higher detection rates.

2. High detection of miner population: The proper use of CHROMagar™ Orientation will correctly pinpoint the presence of a minor population and will help to establish the right diagnosis and therapy.

3. Save time and reduce workload: 

The most common UTI pathogénies is E. coli, found in 40-70 % of infections. CHROMagar™ Orientation has a specificity of 99,3 %* for E. coli.

 

One plate of CHROMagar™ Orientation will give the same information as the combination of the 3 classical plates used for UTI analysis (blood agar, CLED and MacConkey agar). Moreover, since it is easy to differentiate mixed flora on CHROMagar™ Orientation, antimicrobial susceptibility tests can be performed directly from primary isolates without the need of subcultures.**
