ETEST®: Product Safety

Improving Therapeutic Decisions

Antimicrobial resistance testing reagent

ETEST uses a predefined gradient of antibiotic concentrations placed on a plastic strip to determine the Minimum Inhibitory Concentration (MIC) of antibiotics, antifungals and antimycobacterial agents.

ETEST: Product Safety Overview

bioMérieux’s well-established ETEST method demonstrates high performance in Antibiotic Susceptibility Testing, providing a level of precision that other manual AST methods cannot achieve.

Benefits of ETEST

ETEST generates MICs across 15 dilutions, while remaining a cost-effective tool for AST. It can be used in a macromethod format to optimize resistance detection as well.

Complete range

Over 100 antibiotics available for Antibiotic Susceptibility Testing of aerobic bacteria and fastidious organisms such as pneumococci, haemophilus, H. pylori, meningococci, gonococci, anaerobes, fungi and mycobacteria. Please visit our e-catalogue for a list of all available reagents.

ETEST: Product Safety Uses

Veterinary Diagnostics

Veterinary diagnostic laboratories are very frequently required to perform Antibiotic Susceptibility Testing with animal samples. ETEST is the ideal manual method for routine AST operations.

For veterinary laboratories, determining quantitative MIC data is essential to ensure animal health and to avoid any risk of zoonosis, which can be dangerous to humans.

ETEST: Product Safety Options & Accessories

bioTools™ along with a range of ETEST accessories are designed to simplify the handling of ETEST. bioTools is a family of instruments made up of the Retro C80™, Simplex C76™, and Nema C88™ that are easy to use, reduce operator fatigue, save time and improve the quality of results. These tools simplify reading by standardizing inoculation and application of strips in optimal patterns on media plates.

ETEST Accessories

Every Detail Counts

ETEST Measuring Sticks – 5 per package (bioMérieux ref. 559904)

Used with foam packaging to conveniently determine the number of strips remaining. Scaled in 10 strips increments up to 100 strips maximum.

 

ETEST Clamps – 5 per package (bioMérieux ref. 559809)

Used with foam packaging to seal opened foil pouches. Creates a proper seal, and when used with desiccant, ensures humidity does not damage strips.

 

 

 

 

Mini Storage Box with Desiccant (bioMérieux ref. 559900)

The Mini Storage Box includes two desiccant capsules. Extended stability studies have validated its effectiveness in preserving ETEST shelf-life of up to 2 foam packages. Other non-airtight boxes may be suboptimal and cannot guarantee the stability and shelf-life of the strips.

 

 

 

 

Midi Storage Box with Desiccant (bioMérieux ref. 559901)

The Midi Storage Box includes six desiccant capsules. Extended stability studies have validated its effectiveness in preserving ETEST shelf-life of up to 6 foam packages. Other non-airtight boxes may be suboptimal and cannot guarantee the stability and shelf-life of the strips.

 

 

 

Maxi Storage Box with Desiccant (bioMérieux ref. 559902)

The Maxi Storage Box includes twelve desiccant capsules. Extended stability studies have validated its effectiveness in preserving ETEST shelf-life of up to 12 foam packages. Other non-airtight boxes may be suboptimal and cannot guarantee the stability and shelf-life of the strips.

 

 

 

Storage Container (bioMérieux ref. 501603)

The Storage Container can hold one foam package and it includes one desiccant capsule. Extended stability studies prove its effectiveness in preserving ETEST shelf-life. Unused strips have the same expiration date as the original packaging when properly kept in the Storage Container.

 

Applicator Tray (bioMérieux ref. 559909)

The applicator tray makes it easy to set up ETEST panels containing multiple antimicrobials per plate. Simple place the antimicrobial strips of choice into the wells as shown below, and use a manual applicator device such as the Mini Grip-It to place the strips on to agar plates.

 

 

 

Mini Grip-It (bioMérieux ref. 411200)

The Mini Grip-It is a device that makes it easier to grab, hold, and move small and light objects from one place to another. The suction cup picks up hard to handle items such as ETEST strips, antibiotic disks, and glass/plastic cover slips. The whole apparatus can be autoclaved.

 

 

 

Desiccant Capsules - 8 per package (bioMérieux ref. 559709)

ETEST is susceptible to moisture and open strips must be stored with active desiccant. When using alternative storage units, it is mandatory to ensure that desiccant capsules are used with an air-tight container. As desiccant absorbs moisture it will change color from yellow/orange to white. Capsules are reactivated by heating for 2 hours at 70°C or until the orange color is restored.

  1. Active desiccant
  2. Inactive desiccant (reactivate or replace)
