Dear all,
We have a question about susceptibility loincs with the method “method for slow growing mycobacteria”
E.g. for isoniazide and minocycline etcetera
For these agents we can both find loinc codes with this method type but also loinctypes with the general MIC method
As far as I know the gold standard for slow growing mycobacteria is MIC
Now for minocycline I can somehow imagine that you might want to make a distinction between the normal MIC being measured for general bacteria or for rapid growth mycobacteria and the MIC measured in special mycobacteria laboratories for slow growth.
So can we use the following as a rule of thumb?
If an MIC is being measured for slow growing mycobacteria we have to chose loinc codes with “method for slow growing mycobacteria” eg 55156-4 for minocycline
And if an MIC is measured for rapid growing mycobacteria we simply use the standard code for MIC for general bacteria, eg 335-0 for minocycline
Even then, I wonder, wouldn’t it be possible to choose for the general code (eg 335-0) whenever an MIC is performed, regardless of slow or rapid growth?
In another segment of the laboratory report one can see the name of the species and thus it should be possible to infer that is concerns either rapid or slow growing bacteria.
Kind regards, Bram Lestrade
