| Disease | pneumonia | Disease Subtypes | / | ||
| Organ | Lung | Test Sample / Technology Platform | Serum (immunoassay technology) | ||
| Pathobiological Mechanisms | Calcitonin precursor protein without hormonal activity, when bacterial infection, bacterial toxins and inflammatory factors induce a large number of synthesis of multiple tissues and organs throughout the body, and the level is directly related to the severity of bacterial infection. Viral infections or non-infectious inflammation have minimal impact | ||||
| Clinical Availability Status | Clinical application: Mainly used for the auxiliary diagnosis of bacterial pneumonia and guiding the use of antibiotics | ||||
| Notes and Dynamics | It is highly specific to bacterial infection and is a key marker to distinguish bacterial and non-bacterial pneumonia | ||||
