Diagnostic Methods for CT/GC Detection

Different types of diagnostic methods can be used to test for CT/GC^1,2,3:

Method	Sensitivity	Workflow	Time to result	Specimen Stability	Costs
CT Culture	Low	Difficult	48 hrs	Low	High
GC Culture	Moderate	Simple	24-48 hrs	Low	Low
EIA (CT only)	Low-Mod.	Simple	4-8 hrs	High	Low
Probes (CT &GC)	Moderate	Simple	4 hrs	High	Low
NAAT (CT &GC)	High	Moderate	6-8 hrs	High	High

Non-amplified direct probe tests (PACE 2®) are the most widely used non-culture tests for CT and GC. GC culture is widely used but CT culture is performed only rarely due to expense and difficulty of the technique. NAATs have become the gold standard for both CT and GC testing and are gradually displacing other CT/GC methods in the laboratory.
