QuantiFERON-TB Blood Test

The QuantiFERON-TB Blood Test is used to aid in the diagnosis of both latent and active infections with the bacteria that causes Tuberculosis (TB). This test is one of only 2 blood tests for TB approved by the FDA.  Tuberculosis is a bacterial disease that typically affects the lungs.  TB Bacteria is spread through the air from one  person to another.  While TB is not as common in the United States as it once was, there is the still a risk posed by TB infection.  It is estimated that 11 million people in the US have a latent Tuberculosis infection (LTBI).  Diagnosis and treatment of LTBI can prevent it from progressing to active Tuberculosis.  For more information, please see the CDC website

The TB blood test has several advantages over a skin test.  Blood testing requires only one visit to the lab while skin testing requirs multiple visits to a doctor's office.  Blood testing for Tuberculosis is typically more accurate than a skin test.  Skin testing has a higher likelihood of false positive results, especially if a person has been previously vaccinated for TB. 

Customers who are testing to meet requirements for work, school or travel should verify if a TB blood test will be acceptable or if they are required to have a skin test.

Turnaround time for this test is typically 3-5 business days.

Note: Result turn around times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.

Requirements:

This test is time-sensitive and specimens must be received in the laboratory within 14 hours of collection.  To help ensure the most accurate results, it is recommended that specimen collection for this test be performed in the afternoon. 

Results for this test may not be accurate for people under the age of 17 or those with compromised or weakened immune systems.  Please consult your doctor to determine if this test will be appropriate.
