Add a Breakpoint

Updated 11 October 2026 13:13

Step 1

Select the Breakpoints option on the main menu.

Note: The visibility of main menu options is determined by menu permissions. For more information about configuring menu permissions, see: Understanding Menu Permissions.

Step 2

Select the Add Breakpoint button which appears at the top of the screen.

Step 3

The organism selection screen will appear.

You have two options for scoping an organism:

3(a)

Manually using the taxonomy dropdowns

Make a selection for each level in the taxonomy until you have correctly scoped the organism.

Note: Each time you make a selection, the dropdown for the next level down in the hierarchy will appear automatically.

3(b)

Selecting from a locally defined organism group

Use the "organism group" dropdown to choose from a pre-defined local list.

Step 4

When you have finished defining organism scope, click Next to proceed. This appears at the bottom of the screen.

Step 5

The breakpoint criteria screen will appear. Here you define the characteristics associated with the new breakpoint.

Antibiotic
You must explicitly associate a breakpoint with an antibiotic. For information about configuring antibiotics, see: .

Test Method
You must explicitly associate a breakpoint with a test method (i.e. Disk or MIC). For more information about test methods, see: .

Source
You must associate a breakpoint with a set of source guidelines (i.e. CLSI/EUCAST). For more information about source guidelines, see: .

Host
SEDRI-LIMS allows you to configure your own hosts. For more information about this, see:

Specimen Type
You are able to scope a breakpoint association with any number of specimen types.

Special Considerations
Determines whether or not the role is active and can be assigned to users.

Enabled
Determines whether or not the breakpoint is active and usable.

Note: Any field marked with

is mandatory.

Step 6

When you have finished defining the breakpoint characteristics, click Next to proceed. This appears at the bottom of the screen.

Step 7

The breakpoint definition window will appear - Here you define the measurements and ranges for levels of susceptibility.

Breakpoint

This dropdown is used to select a susceptibility definition (i.e. Susceptible, Intermediate or Resistant). Susceptibility definitions can be configured, for a detailed guide on how to do this see: .

Start/End

Use these fields to define the scope of a susceptibility definition.

Add Line

This button is used to add additional susceptibility definition lines to the breakpoint. Lines can be removed by clicking .

Step 8

When you have finished entering susceptibility lines click Finish to add the breakpoint.

Step 9

Verify that the newly added breakpoint appears in the list.
