Pneumocystis jirovecii by PCR
Also known as: PCP PCR
Use
This test is used to detect the presence of Pneumocystis jirovecii in respiratory specimens using PCR. It is the preferred test for assessing immunocompromised patients who do not have HIV. The results are crucial for diagnosing PCP pneumonia and must be interpreted considering the patient's risk factors, clinical presentation, and radiographic imaging.
