What is analysed?

Interferon gamma (IGRA) testing focuses on specific elements related to the immune response to tuberculosis. It assesses the release of interferon gamma in response to mycobacterium tuberculosis antigens.

What does the result of the test mean?

The results of IGRA testing provide insights into the patient's exposure to tuberculosis. Positive results indicate the presence of a tuberculosis infection, while negative results suggest the absence of an active infection.
 

Why is this type of analysis needed?

IGRA analysis is crucial for tuberculosis diagnosis and management. It offers a more specific evaluation compared to traditional methods, aiding in the early detection and appropriate treatment of tuberculosis.
 

When should patients undergo the analysis?

The timing of IGRA testing varies based on the clinical scenario. It is recommended for individuals with suspected tuberculosis, those in close contact with TB patients, or those at risk due to other medical conditions.
 

Required sample

IGRA testing typically requires a blood sample. This non-invasive method makes it a convenient and reliable way to assess tuberculosis infection.
 

Is any type of preparation required?

In most cases, no specific preparation is needed before undergoing IGRA analysis. Unlike some diagnostic tests, fasting or medication adjustments are not typically required.
 

How is the test conducted?

The IGRA test involves exposing a blood sample to TB antigens and measuring the interferon gamma released. The procedure is well-tolerated and provides rapid and accurate results.
 

Normal values

Normal values for IGRA are typically defined based on the amount of interferon gamma produced in response to TB antigens. These values serve as a reference point for interpreting test results.
 

Significance of altered values

Values outside the normal range may indicate active tuberculosis infection. Understanding the significance of altered values is crucial for healthcare providers to determine appropriate intervention and treatment.
