BIOMIC V3 reads 90mm to 150mm round plates, and 120mm square plates.
2. How many antibiotic disks may be tested on each plate?
We recommend a maximum of 6 disks (90mm plates) or 12 disks (150mm plates) per plate. However, more disks can be added to each plate but do not place highly active antibiotics next to each other. This may result in unwanted heavy zone overlapping, synergy, antagonism or an additive effect.
3. Can BIOMIC V3 automatically read Etests (bioMerieux), MIC Test Strips (Liofilchem), and M.I.C.E strips (Oxoid)?
Yes. BIOMIC V3 provides automated strip location, drug code recognition, MIC zone reading, and S-I-R interpretation. After the plate is placed in the drawer, an enlarged plate image is displayed and confirmed on-screen by the user. Automated strip code recognition prevents user entry error by confirming the correct drug code. No prior setup is required.
4. Can antibiotic disks and Etest/MIC strips be read on the same plate?
Yes. A combination of disks and strips may be read on the same plate.
5. How many Etest/MIC strips may be tested on each plate?
We recommend a maximum of 2 strips (90mm round plates) or 6 strips (150mm round plates) per plate.
6. How does BIOMIC V3 read Etest/MIC strips with inner colonies/haze/swarming?
BIOMIC V3 reads each strip based on the specific drug and/or organism per manufacturer's instructions.
7. How many expert rules are available in BIOMIC V3?
BIOMIC V3 contains over 2500 expert rules based on CLSI, EUCAST, BSAC and published recommendations. Expert rules detect antibiotic resistance, warn users of unlikely test results, and provide additional test recommendations. Expert rules may be turned on or off.
8. Are expert rule messages printed on test reports?
Yes. Expert rule messages that may be helpful to physicians are printed on test reports as footnotes. Expert rule messages that may be helpful to technologists are shown on-screen.
9. If an expert rule is triggered and changes a test result interpretation (category S,R), is it shown on-screen?
Yes. When an expert rule changes a test result interpretation (e.g. S to R, or deleted), the original and expert interpreted test results are both shown on-screen, but only the changed results are printed or sent to the LIS/LIMS.
10. Can BIOMIC V3 detect ESBL, MRSA, and VRSA?
Yes. BIOMIC V3 utilizes CLSI, EUCAST and BSAC recommended test methods to detect and report these resistance mechanisms.
11. Can BIOMIC V3 read and interpret the D-Test?
Yes. BIOMIC V3 instantly reads, interprets, and records D-Test results when erythromycin and clindamycin disks are placed, and the appropriate organism conditions (macrolide-resistant isolates of S. aureus, coagulase-negative Staphylococcus spp., or beta-hemolytic streptococci) recommended by CLSI are met. When a flattening of the clindamycin zone is detected and displayed on-screen, these isolates are reported as ‘clindamycin resistant’.
12. What are BIOMIC V3 user expert rules?
User expert rules are laboratory specific rules created by the customer. The two types of user expert rules are “Do Not Report drug when…” and “Insert Comment when…”
Example 1: Do not report Ampicillin for Wound cultures.
Example 2: Do not report Cefepime if Oxacillin is Susceptible.
Example 3: If Ampicillin is Resistant for Staph, insert comment ABC.

Yes. Users can adjust all zone measurements on-screen.
17. How does BIOMIC V3 read and interpret trimethoprim sulfa zones?
With trimethoprim and sulfonamides, antagonists in the agar medium may allow slight growth. BIOMIC V3 disregards this slight growth and the zone is measured at approximately 80% inhibition as recommended by CLSI.
18. How does BIOMIC V3 read difficult (ex: low growth / fastidious / blood) plates?
BIOMIC V3 reads difficult plates very well, and it includes image enhancement functions to assist in the reading of difficult plates. This includes contrast enhancement for dark or blood plates (example: hemolytic streptococci) and growth enhancement for low growth, fastidious organisms (example: enterococci).
19. How does BIOMIC V3 interpret small colonies inside the zone of inhibition?
Small colonies are visible on-screen. BIOMIC V3 interprets these colonies based on specific drug-organism combinations. Generally, if BIOMIC V3 detects 4-5 readily visible colonies within the zone of inhibition, the automated zone measurement will be drawn inside of these colonies. For specific organisms, such as Staph, the zone is automatically drawn inside any colonies observed. This is also true for automated Etest/MIC strips readings.
20. How does BIOMIC V3 interpret double zones and feathered edges?
Drug-organism combinations that produce double zones or feathered edges are programmed to be interpreted by BIOMIC V3. (Example: E. coli and ciprofloxacin feathered edges are interpreted where no growth is visible by eye, whereas Candida and fluconazole double zones read the outer zone.)
21. Does BIOMIC V3 automatically recognize antibiotic disks on the plate?
Yes. BIOMIC V3 automatically recognizes disk codes from several manufacturers including Oxoid, BD and Bio-Rad. Digital imaging technology locates disk positions, recognizes disk codes, and measures zone diameters.
22. How precisely do antibiotic disks need to be positioned on test plates?
BIOMIC V3 searches an area around the disk position on the plate. After locating the disk location and drug code, a zone measurement is automatically drawn on-screen. BIOMIC V3 compensates for disk position variation caused by disks flipping over or shifting. For best results, always use a disk dispenser.
23. Is it necessary to remove labels and writing from the bottom of test plates?
Yes. We recommend placing labels on the side of test plates to prevent interference with image analysis. Do not put labels on the bottom of the plate. Write on plates with a fine point pen in red, green or yellow ink. Wide black writing may interfere with image analysis.
24. Should plate lids be removed prior to reading?
Yes. Plate lids should be removed during reading to optimize the imaging quality.
IV. Organism Identification
