What does this TB Blood Test check for?
This TB blood test helps screen for immune response to Mycobacterium tuberculosis, the bacteria that causes tuberculosis.
It may be used as an aid in identifying TB infection, including latent TB infection or active TB disease, but it does not determine by itself whether TB is active.

Why choose a TB blood test?
A TB blood test is often preferred because it requires one blood draw visit. A TB skin test requires placement and a return visit 48 to 72 hours later for reading.
TB blood testing may be especially useful for people who received the BCG vaccine, people who cannot return for a TB skin test reading, or people whose form specifically asks for an IGRA or QuantiFERON Gold test.
TB Blood Test and BCG vaccine
Many people born outside the United States received a vaccine called BCG.
BCG vaccination may cause a false-positive result on a TB skin test. TB blood tests are not affected by prior BCG vaccination in the same way and may be preferred for people who have received BCG.
TB Blood Test vs. TB Skin Test
A TB blood test requires one blood draw visit. A TB skin test requires test placement and a return visit for reading.
A TB blood test is often preferred for people with prior BCG vaccination. A TB skin test may be more affordable but requires two visits.
If your school or employer specifically requests one type of TB test, use the test that matches the wording on your requirement.

Is this the same as QuantiFERON Gold?
Yes. This product is for the TB blood test commonly known as QuantiFERON Gold or QuantiFERON TB Gold. It may also be referred to as an IGRA TB blood test.
Does this require two visits?
The TB blood test requires a blood draw visit. Unlike a TB skin test, it does not require a separate return visit just to have a skin test read.
Can this test diagnose active TB?
No. This test is used as a screening blood test and does not diagnose active tuberculosis by itself.
A positive TB blood test may require medical follow-up, review of symptoms, chest imaging, or additional evaluation by a licensed healthcare professional or public health department.
What if my TB blood test is positive?
A positive TB blood test does not automatically mean active tuberculosis disease. It may indicate TB infection and usually requires follow-up with a healthcare professional.
If your result is positive, follow the instructions from your school, employer, healthcare provider, or local health department.
Is a doctor's order included?
Yes. A doctor's order is included with your purchase. Your lab order and next-step instructions are sent electronically after checkout.

No. Insurance is not required to order through SchoolTiters. Pricing is all-inclusive for the standard lab order, with no surprise lab or collection fees.
