Carbapenemase Detection, Modified Hodge Test
Method Description Describes how the test is performed and provides a method-specific reference
A standardized suspension of Escherichia coli ATCC 25922 is streaked across the surface of Mueller-Hinton agar plates. A single antibiotic disk is dropped onto the center of the plate. The carbapenems ertapenem and meropenem are tested. The patient strain is streaked in a thin straight line from the edge of the plate to the disk. Enhanced growth at the intersection of the streak with the zone of inhibition indicates carbapenemase production.(Clinical and Laboratory Standards Institute/NCCLS. 2009.

Day(s) and Time(s) Test Performed Outlines the days and times the test is performed. This field reflects the day and time the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time required before the test is performed. Some tests are listed as continuously performed, which means assays are performed several times during the day.
Monday through Sunday
Analytic Time Defines the amount of time it takes the laboratory to setup and perform the test. This is defined in number of days. The shortest interval of time expressed is "same day/1 day," which means the results may be available the same day that the sample is received in the testing laboratory. One day means results are available 1 day after the sample is received in the laboratory.
Performing Laboratory Location The location of the laboratory that performs the test
