A QuantiFERON-TB Gold blood test (an IGRA) that checks for exposure to the bacteria that causes tuberculosis. Suited to people who may have been exposed to TB or are unsure of their BCG vaccination history.
1 biomarker as listed by Better2Know.
Tuberculosis is spread through the air and mainly affects the lungs. This test uses the QuantiFERON-TB Gold method, a blood-based alternative to the traditional tuberculin skin test, and is aimed at people who think they may have been exposed to TB, have lived in or visited a country where it is more common, or are unsure whether they received the BCG vaccine.
We have no directly comparable tests in our records for this one, but at £295 it is more than double the £129 median across the immunity and infection tests we track, a 129% premium. It requires a single blood sample taken at a Better2Know clinic rather than an at-home option.
The value for money score is the lowest of any criterion for this test, reflecting how far above the category median it sits. It scores well for clarity, with a detailed listing covering sample type, collection and turnaround, but scores lower for results and follow-up, since results are not reviewed by a doctor as standard.
This is worth considering if you think you have been exposed to TB, have spent time in a country where it is more common, or are unsure of your BCG vaccination status. Because it costs significantly more than the typical immunity test we track and we have no similar tests in our records to compare it against, it is best chosen when you specifically need this test rather than as a general check. The provider notes the test cannot tell the difference between a latent and an active infection and is not suitable if you are immunocompromised or taking immunosuppressive drugs; a GP can advise on the right test for your situation.
A blood sample is taken from your arm at a Better2Know clinic and sent to the lab for analysis, with results typically ready within around 3 working days. Results are uploaded to your secure online Patient Area. Results are not reviewed by a doctor as standard, though Better2Know notes the test can return a negative, positive or indeterminate result, and a positive result is treated as strongly indicative of TB infection, per the provider.
This is a QuantiFERON-TB Gold blood test for tuberculosis exposure, taken at a Better2Know clinic with results in around 3 working days. At £295, it is more than double the £129 median across the immunity and infection tests we track, and the pricier of the two immunity tests in this bundle. There are no comparable tests in our records to weigh it against directly.
The listing publishes a detailed description, the full biomarker list, a stated turnaround, clear collection options, the sample type; it does not state what the report looks like.
