Comment
It is not clear whether this term was meant to represent assays that detect isolates susceptible to carbapenems or assays that detect carbapenemase-producing isolates. The term name suggests the former but the term description suggests the latter since it mentions the Modified Hodge test (MHT).
Map-To Long Common Name Mapping Guidance

86930-5 Carbapenemase [Presence] in Isolate For detection of carbapenemase-producing isolates

Term Description

The Modified Hodge Test (MHT) detects carbapenemase production in isolates of Enterobacteriaceae. In the United States, the most common carbapenemase found in Enterobacteriaceae is the Klebsiella pneumoniae carbapenemase (KPC). Other carbapenemase, like the metallo β lactamase (MBL) and the SME-1 in Serratia marcescens, can also produce a positive MHT, but are found infrequently in the United States.

Carbapenemase production is detected by the MHT when the test isolate produces the enzyme and allows growth of a carbapenem susceptible strain (E.coli ATCC 25922) towards a carbapenem disk. The result is a characteristic cloverleaf-like indentation.
