Product Description
Levofloxacin LEV 5 µg is a HiMedia antibiotic sensitivity disc intended for in vitro antimicrobial susceptibility testing of bacterial cultures by a standardised agar disc diffusion method. Each filter-paper disc contains 5 µg of levofloxacin.
HiMedia supplies the product under catalogue number SD216. The manufacturer identifies the official disc symbol as “LE,” and both sides of the 6 mm disc are printed with “LE 5” for easy identification. The product name may sometimes be written commercially as LEV 5 µg, but laboratories should use the manufacturer’s official LE 5 marking when checking the disc and recording the product code.
During testing, a standardised bacterial suspension is spread uniformly over an appropriate agar medium. The Levofloxacin LE 5 disc is placed on the inoculated surface using sterile forceps or a compatible disc dispenser. After incubation under the conditions specified for the test organism, the diameter of the complete inhibition zone is measured.
Zone measurements must be interpreted using the current CLSI, EUCAST or another approved standard applicable to the organism and laboratory programme. Breakpoints, quality-control ranges and organism-specific recommendations can change, so outdated criteria should not be used automatically.

Product Overview
Antibiotic sensitivity discs are standardised filter-paper discs impregnated with a defined quantity of an antimicrobial agent. When placed on an inoculated agar plate, the agent diffuses into the medium and may inhibit growth of a susceptible organism, producing a measurable zone around the disc.
Levofloxacin is a fluoroquinolone antimicrobial agent. In this product, each disc contains a specified potency of 5 µg. The product is a laboratory susceptibility-testing reagent and is not a tablet, injection or medicinal dosage form.
The inhibition-zone diameter can be influenced by the organism, medium, agar depth, pH, inoculum density, disc potency, disc storage, incubation atmosphere, incubation duration and measurement technique. A dependable result therefore requires a controlled test method and acceptable quality-control performance.

Basic Test Procedure
The following is a general workflow only. The current approved method, HiMedia instructions and the laboratory’s standard operating procedure must be followed.
- Prepare a suitable susceptibility-testing agar plate at the required depth.
- Prepare the test organism inoculum to the method-specified density, commonly using an approved turbidity standard.
- Inoculate the complete agar surface uniformly with a sterile swab.
- Allow the plate surface to absorb excess moisture for the method-specified period.
- Place the Levofloxacin LE 5 disc aseptically using sterile forceps or a compatible disc dispenser.
- Maintain the required spacing between adjacent antimicrobial discs.
- Incubate at the temperature, atmosphere and duration specified for the organism.
- Measure the diameter of complete inhibition zones with a suitable calibrated measuring device.
- Interpret and report the result using the current approved breakpoint and quality-control standard.
Recommended Media and Testing Conditions
Mueller Hinton Agar is commonly used for disc diffusion testing of rapidly growing non-fastidious aerobic bacteria. Fastidious or special organisms may require supplemented media, alternative media or different incubation conditions.
The exact medium, agar depth, inoculum density, disc spacing, incubation atmosphere, temperature, duration and interpretation criteria must be selected for the organism and current approved method. One set of conditions must not be applied to every organism.
Storage and Shelf-Life
On receipt, store HiMedia Levofloxacin SD216 discs at -20°C under dry conditions. Keep the discs with the desiccant supplied in the individual pack and use the product before the expiry date shown on the label.
- Return the discs to the recommended storage condition promptly after use.
- Keep the vial, cartridge or pack tightly closed.
- Protect the discs from moisture and prolonged room-temperature exposure.
- Do not use wet, damaged, contaminated or expired discs.
- Follow the laboratory procedure for equilibration before opening cold packaging.
- Record the lot number, opening date, storage condition and expiry date.
- Discard discs if storage conditions have not been maintained or product performance is uncertain.
Quality-Control Considerations
Each new lot or shipment should be evaluated under the laboratory’s quality-control programme using appropriate reference organisms, approved media and standard incubation conditions.
Zone diameters can be affected by agar depth, medium pH, cation concentration, inoculum density, disc potency, storage, incubation conditions and measurement technique. Results should not be reported when required quality-control performance is unacceptable.
Use the current CLSI, EUCAST or other approved quality-control ranges and interpretive criteria. Historical ranges should not be copied into routine practice without confirming that they remain current and applicable.
Important Limitations
- Disc diffusion is an in vitro laboratory method and does not by itself predict the complete clinical outcome for a patient.
- The test result depends on correct organism identification, inoculum preparation, medium, incubation and interpretation.
- This product must not be administered to humans or animals.
- The official HiMedia marking is LE 5; do not confuse it with another antimicrobial disc or potency.
- Susceptibility categories must be assigned using a current approved standard applicable to the organism.
- A small or absent inhibition zone should not be interpreted without confirming test validity and quality-control performance.
- The product is not intended for home testing or use by untrained individuals.
- An antibiotic disc result should not replace professional clinical judgement or the laboratory’s authorised reporting process.
Safety and Handling
- Use only in a properly equipped microbiology laboratory.
- Handle bacterial cultures according to the required biosafety level and institutional procedure.
- Wear appropriate gloves, laboratory clothing and eye protection.
- Apply discs with sterile forceps or a validated disc dispenser.
- Do not touch the discs with bare hands.
- Avoid unnecessary exposure of the discs to moisture and room air.
- Decontaminate used plates, cultures and disposable materials before disposal.
- Follow the product instructions, institutional biosafety rules and applicable waste regulations.
