LOINC Code 79177-2: C. difficile glutamate dehydrogenase and toxins A+B IA.rapid Ql (Stl)

What is this code?

LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component Clostridioides difficile glutamate dehydrogenase & toxins A+B. It is commonly used with the system or sample type Stool.

When is it used?

• Used in lab systems, EHRs, and clinical data exchange.
• May identify a test, observation, survey item, or clinical document request rather than a diagnosis.
• Status: ACTIVE
• Order vs observation: Both
• Method: IA.rapid

What it does not mean

• The code identifies the observation or test, not the actual result.

Key facts

• Clostridioides difficile glutamate dehydrogenase and toxins A+B [Presence] in Stool by Rapid immunoassay
• Clostridioides difficile glutamate dehydrogenase & toxins A+B
• The detection of both C. difficile antigen (glutamate dehydrogenase, GDH) and toxins A and B in a stool specimen. This term was created for, but not limited in use to, Alere's C. diff Quik Chek Complete(R), a rapid immunoassay that screens for the presence of C. difficile GDH antigens and confirms the presence of toxigenic C. difficile by detection of toxins A and B. The Alere Quick Chek Complete assay takes 25 minutes to complete, including 15 minutes for specimen incubation and 10 minutes for reaction with substrate.
