IRIS-100 FAQ

Questions about our
INHIBITION ZONE READER
with automatic documentation

How fast can IRIS-100 do the measurement?

It takes IRIS-100 around 3 seconds to identify the disks and measure the inhibition zones.

Is it possible to use square petri dishes?

IRIS-100 can handle both round and square petri dishes.

How certain are the measurements with IRIS-100 compared to manual measurements?

IRIS-100 has been tested and validated in cooperation with Hvidovre Hospital.

Inhibition zones for gram positive and gram negative bacteria were measured by IRIS-100 and by manual measurement respectively. The average conformity of the two different methods were calculated and compared. The results showed an average conformity of 99 % for the gram positive bacteria and 96 % for the gram negative bacteria.

The identification of the antibiotic discs is done 99% certainty.

More test-results are coming.

How much space is required for IRIS-100?

The size of IRIS-100 is 18 x 18 x 21 cm and it weighs 4 kg.

What is Antimicrobial Susceptibility Testing (AST) and why is it important?

Antibiotic susceptibility testing (AST) is the measurement of the susceptibility of bacteria to antibiotics. It is used because bacteria may have resistance to some antibiotics.

An effective antibiotic treatment of bacterial infections can be crucial for patients. Some infections are life threatening and requires fast treatment with the right antibiotic in the optimal amount.

Offering early treatment with specific antibiotic drugs, increases patient safety, prevents the development of bacterial resistance and reduces cost in the health care system.

What is Antimicrobial Resistance (AMR)?

Antimicrobial Resistance (AMR) develops when bacteria, fungi or viruses are exposed to antibiotics, antifungals or antivirals. As a result, the antimicrobials become ineffective and infections may persist. In addition, medical interventions including surgery, chemotherapy and stem cell therapy may become impossible.

Furthermore, antibiotic resistance can prolong the treatment of normally easily treated infections since you need to change to another antibiotic agent or combination when the prescription is not working. The risk of antibiotic resistance development is increased because of this procedure as well as the widespread habit of using broad-spectrum antibiotics.

Is IRIS-100 fully automatic?

IRIS-100 will automatically register and identify the antibiotic discs and measure the inhibition zones, but it is the responsibility of the laboratory technician to check the results, which can be adjusted manually if needed.
