How is a susceptibility test done?
The test is done by taking a sample from the infected site. The most common types of tests are listed below. A health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial.
How do you use ETEST strips?
Just apply the strip to an inoculated agar plate either manually or using the optional ETEST® instruments or accessories (e.g. Retro, Simplex, Nema, or MiniGrip It) and incubate.
What is broth Microdilution method?
Broth microdilution is a method used to test the susceptibility of microorganisms to antibiotics. It is the most commonly used method to perform this test in the United States.
How does the etest work?
Etest (previously known as the Epsilometer test) is a way of determining antimicrobial sensitivity by placing a strip impregnated with antimicrobials onto an agar plate. A strain of bacterium or fungus will not grow near a concentration of antibiotic or antifungal if it is sensitive.
How do you perform a broth Microdilution method?
In this method, wells are filled with broth containing different concentrations of the antibiotic. These are then inoculated with bacteria and incubated overnight. The next day, the minimal inhibitory concentration is determined.
How do I know if my MIC is etest?
The MIC value is read from the scale in terms of µg/mL where the ellipse edge intersects the strip. After the required incubation period, the minimum inhibitory value is read where the edge of the inhibition ellipse intersects the side of the strip.

How is Etest used in the treatment of disease?
ETEST is a valuable diagnostic solution used to help guide and manage therapy when on-scale MICs are needed for treatment decisions. ETEST is part of an integrated ID/AST offer by bioMérieux to help complete your AST pathway and support your antimicrobial stewardship initiatives.
How is Etest used in the AST pathway?
ETEST is part of an integrated ID/AST offer by bioMérieux to help complete your AST pathway and support your antimicrobial stewardship initiatives. ETEST is also recognized as a flexible, cost-effective, and accurate tool used to detect or confirm emerging resistance and can provide faster availability of MICs for newer agents.
How many antimicrobials are on an Etest strip?
ETEST ® is a predefined, stable gradient of 15 antimicrobial concentrations on a plastic strip. It is a simple, cost-effective tool that offers results when you need more precision than what automated or Kirby-Bauer antimicrobial susceptibility tests (AST) tests provide.
