UTI Diagnostic Kit#4fa25a
Intended Use
Recommended for diagnosis of Urinary Tract Infection and subsequent antibiotic susceptibility testing.
Kit Contents
- HiCrome™ UTI Agar (SM1353): 1x100ml
- Mueller Hinton Agar (SM173): 2x100ml
- Sterile Petri plates: Empty 90 mm (15 Nos)
- Octodiscs: OD022/R - 5 Nos, OD021/R - 5 Nos, (Each OD is a combination of 8 different antibiotics)
- Sterile Uricol : 5 Nos
Directions
- Collect the midstream urine sample in sterile uricol.
- Process the samples as per the protocol.
- SM1353 and SM173-Slightly loosen the cap and melt the medium in water bath at 100°C. Cool to 45-50°C and pour the medium into empty sterile 90 mm Petri plates.
- Isolate the organisms from the urine sample on HiCrome™ UTI Agar plate prepared from SM1353. Incubate at 35-37°C for 18-24 hours.
- The most predominant organism (causative agent) is then selected for sensitivity study.
- 0.1 OD colony suspension of the suspected organism is prepared and then swabbed on Mueller Hinton Agar plates plate prepared from SM173.
- Place OD021/R and OD022/R on the swabbed plates. Incubate at 35-37°C for 18-24 hours.
- Interpret the results after incubation.
Principle And Interpretation
Urinary tract infections are bacterial infections affecting parts of urinary tract. The common symptoms of urinary tract infection are urgency and frequency of micturition, with associated discomfort or pain. The common condition is cystitis, due to infection of the bladder with a uropathogenic bacterium, which most frequently is Escherichia coli, but sometimes Staphylococcus saprophyticus or especially in hospital-acquired infections, Klebsiella species, Proteus mirabilis, other coliforms, Pseudomonas aeruginosa or Enterococcus faecalis (1). HiCrome™ UTI Agar is also recommended for dip stick procedures and as dip inoculum transport medium for urine specimens. Inoculate the medium immediately after urine collection (5, 2). After isolation of the organism sensitivity of the organism to antimicrobial agents is checked on Mueller Hinton Agar by disc diffusion method as described in CLSI Approved Standard (6). The susceptibility is determined by comparing with CLSI standards (7). For Susceptilbility testing OD021R or OD022R are used. These series of discs gives the privilege to study large number of antibiotics at one time.
Type of specimen
- Clinical samples - urine
Specimen Collection and Handling
For clinical samples follow appropriate techniques for handling specimens as per established guidelines (3,4). After use, contaminated materials must be sterilized by autoclaving before discarding.
Warning and Precautions
In Vitro diagnostic Use only. Read the label before opening the container. Wear protective gloves/protective clothing/eye protection/face protection. Follow good microbiological lab practices while handling specimens and culture. Standard precautions as per established guidleines should be followed while handling clincal specimens. Saftey guidelines may be referred in individual safety data sheets.
Limitations
- Initiation of antibiotic therapy, before collection of sample, low urine pH (less than 5) etc. may result in low bacterial count from infected patients.
- This medium is recommended for susceptibility testing of pure cultures only.
- Inoculum density may effect the zone size. Heavy inoculum may result in smaller zones or too less inoculum may result in bigger zones.
- As antimicrobial susceptibility is carried with antibiotic disc, proper storage of the disc is desired which may effect the potency of the disc.
Performance and Evaluation
Quality Control
Performance of the medium is expected when used as per the direction on the label within the expiry period when stored at recommended temperature.
