Tuberculosis testing

QuantiFERON-TB Gold Plus – world's leading tuberculosis blood test

What types of TB infection testing are available?

When it comes to TB testing, accuracy and speed are crucial. Healthcare providers will test for TB infection using either a TB blood test or a TB skin test. Both types of TB test can reveal whether a person is likely to be infected with TB bacteria.

There are key differences when comparing the TB skin test to the TB blood test . A TB skin test requires injecting tuberculin under the skin and checking the reaction 2–3 days later, while a TB blood test measures the immune response from a blood sample.

QuantiFERON-TB Gold Plus is the world’s leading TB blood test. It features unique CD8 T-cell technology to provide a more complete assessment of the patients’ immune response to TB.

What is an IGRA test?

An Interferon-Gamma Release Assay (IGRA) is a the most common type of blood test used to detect TB infection. It measures the release of interferon-gamma by immune cells in response to TB-specific antigens, providing results without the need for a follow-up appointment.

What is QuantiFERON?

The QuantiFERON TB test is a reliable blood test for detecting tuberculosis infection. Using IGRA technology, it measures the immune response to TB with a single visit. QuantiFERON offers proven accuracy, efficiency, and convenience, providing objective results that are unaffected by BCG vaccination.

Cost-effectiveness in TB testing: Unlock strategies and savings

Worried that the world’s leading TB blood test might cost you more? Let's put those fears to rest: QuantiFERON-TB Gold Plus offers both accuracy and cost-efficiency.

The traditional Tuberculin Skin Test (TST) might seem less expensive at first glance, but it comes with hidden costs for patients and caregivers. It doubles the workload and cost with two visits, more paperwork and training. Not only this, false positives from TST can lead to unnecessary treatments and waste of resources.

How much is a QuantiFERON TB test?

QuantiFERON TB testing is cost-effective compared to the tuberculin skin test. The TST requires multiple visits, and increased false-positive results from prior BCG-vaccination can lead to unnecessary treatment and waste of resources. QuantiFERON simplifies this with one visit and one objective result, saving time and reducing errors.
