Result interpretation criteria for common bacteria

Test results for items listed below will be reported in the following manner, according to the following SRL criteria:
(Reference: Clinical Microbiology Procedures Handbook - 4th edition)

Standard sets for drug susceptibility testing

• According to the bacterial species (groups) detected, a combination of agents that is effective will be used for testing.
• For those other than the bacterial species (groups) listed above, SRL will select agent(s) for use.
• Please note that the standard patterns of agents may not be used depending on the bacterial species (groups) detected.
• Susceptibility testing is not performed for the normal flora.
• Results of the susceptibility test will be reported using the following categories：
  • S：Susceptible
  • I ：Intermediate
  • R：Resistant

• ▲：VCM will be reported if C. difficile is detected.
• ◎：Testing for N. gonorrhoeae will be performed using disk diffusion method.

Bacteria test collection method

• Be sure to indicate the name of the material to be tested or the site from which the material was collected.
• If the target organisms are Neisseria gonorrhoeae or Neisseria meningitides, store at .
• Test material for anaerobic culture should be collected in Seed Tube II.
• Note that the number of days required will vary depending on the target bacteria and other factors.

Handling Instructions for Seed Tube II

■ Fluid specimens (paracentesis fluid, digestive fluids, etc.)

1. Sterilize the puncture site (the small circle on the rubber cap) with rubbing alcohol or other sterile cotton.
2. Puncture the syringe needle vertically into the puncture site and inject the fluid specimen.
3. Attach the tube label and transport.
4. Specimens should be tested immediately. If preservation is unavoidable, store at .

■ Solid specimens (pus, feces, tissue fragments, etc.)

1. Sterilize the rubber cap with sterile alcohol cotton, etc.
2. Remove the rubber cap and insert a solid specimen. Insert the specimen all the way into the agar.
   (Note) Cotton swabs up to 7 cm in length can be inserted.
   Anything more than that should be cut off.
3. Quickly and securely close the rubber cap.
4. Attach the tube label and transport.
5. Specimens should be tested immediately. If preservation is unavoidable, store .

Helicobacter culture identification collection method

Handling Instructions for Seed Tube HP

1. Place the collected “gastric biopsy tissue” immediately into the collection container (C20) and insert it below the black line.
2. Specimens should be stored within 30 minutes and requested on the same day.

Environmental Inspection Collection Methods

Hospital environment (wipe method)

Wipe a specific area of the specimen (usually 10cm x 10cm) well with the cotton swab (moistened with medium beforehand) provided with the eSwab105 Regular FLOQ Swab, and re-insert the swab into the medium before submitting it.

Hospital environment (stamp method)

Remove the cap of the stamping medium (C30), and gently press the surface of the medium onto the specimen, being careful not to touch the surface with your fingers. After about 5 seconds, put the cap back on and submit the specimen.
