Tuberculosis (TB) Gold Blood Test

The Tuberculosis Blood Test is a modern screening test that detects infection with Mycobacterium tuberculosis, the bacteria that causes tuberculosis, commonly known as TB. TB is an airborne infectious disease that most often affects the lungs, but it can also impact the brain, kidneys, spine, and other organs. Early detection is essential because untreated TB can become serious and even life-threatening.

TB spreads through the air when a person with active lung or throat TB coughs, sneezes, speaks, or sings. Tiny droplets containing the bacteria can remain suspended in the air and be inhaled by others. Not everyone who is exposed becomes sick right away. Some people develop active TB disease, while others develop latent TB infection, meaning the bacteria are present but inactive and cause no symptoms.

This test uses the QuantiFERON TB Gold blood test, an FDA-approved method that measures your immune system’s response to TB bacteria. Unlike the traditional skin test, this blood test requires only one visit and is not affected by prior BCG vaccination. It offers accurate, reliable results without the need to return for test interpretation.

A positive result indicates TB infection and requires follow-up evaluation to determine whether the infection is latent or active. A negative result suggests TB infection is unlikely. Early identification allows for timely treatment, reducing the risk of complications and preventing spread to others.

What Is Included In This Test?

This screening includes:

• QuantiFERON TB Gold blood test
• Laboratory analysis of immune response to TB-specific antigens
• Clear positive or negative result interpretation

Results are typically available within five to seven business days due to the specialized testing process.

Why Does This Test Matter?

Tuberculosis remains a global health concern and can spread silently before symptoms appear. Because TB may initially cause mild or no symptoms, screening is critical for early detection and prevention.

Latent TB infection is not contagious, but it can progress to active TB disease if left untreated. Identifying latent infection allows for preventive treatment that significantly reduces future risk.

Active TB can cause chronic cough, chest pain, weight loss, fever, and night sweats. If untreated, it can damage organs and spread to others. Early testing protects both your health and the health of those around you.

Many employers, schools, healthcare facilities, and immigration programs require documented TB screening. This blood test provides a convenient and reliable way to meet those requirements.

Who Should Consider This Test?

You should consider TB testing if you:

• Have been in close contact with someone diagnosed with TB
• Work in healthcare, education, or correctional facilities
• Are required to show proof of TB screening for employment or school
• Have traveled to or lived in areas where TB is common
• Have a weakened immune system
• Want a reliable alternative to the skin test
