I have been in contact with someone who has TB
You may be referred to the TB clinic because you have been identified as a contact of someone diagnosed with TB.
Being a contact does not mean you have TB.
You may be offered:
- A TB blood test (IGRA)
- A tuberculin skin test (Mantoux test)
- A chest X-ray
The timing of these tests depends on when you were exposed to TB, so they may not always be carried out immediately.
It is important to attend screening even if:
- You previously received a BCG vaccination.
- You feel completely well.
- You have had a normal chest X-ray in the past.
I need TB screening before starting biologic treatment
Your hospital specialist may request TB screening before starting biologic medication for conditions managed by:
- Rheumatology
- Gastroenterology
- Dermatology
- Neurology
- Other specialist services
Biologic medicines suppress the immune system, and some can increase the risk of latent TB becoming active.
Screening normally includes:
- A TB blood test (IGRA)
- A chest X-ray
If latent TB infection is identified, treatment may be recommended before biologic therapy begins.
Your specialist team will arrange the referral to our TB Service.
These would work well as expandable FAQ sections underneath your main content.
Can I still get TB if I had the BCG vaccination?
Yes. The BCG vaccine helps protect against some severe forms of TB, particularly in children, but it does not provide complete protection against all types of TB.
You should still attend TB screening and assessment if you are advised to do so, even if you have previously received the BCG vaccine.
Is TB hereditary?
No. TB is not an inherited condition and does not run in families through genetics.
However, family members may be exposed to the same person with infectious TB, which is why household contacts are sometimes offered screening.
Can I go to work, school or university?
Most people with latent TB infection (LTBI) can continue their normal daily activities because they are not infectious.
If you have active TB affecting the lungs, the TB team will advise you whether you need to stay away from work, school or other settings for a short period until treatment has reduced the risk of spreading infection.
Our team will discuss this with you individually.
Can I be around my family and friends?
If you have latent TB infection (LTBI), you cannot pass TB to anyone else and can continue normal contact with family and friends.
If you have active TB, the TB team will advise whether any precautions are needed and whether people close to you should be offered screening.
Are TB medicines safe?
TB medicines are generally safe and very effective.
As with all medicines, side effects can occasionally occur. If treatment is recommended, we will explain possible side effects and arrange any monitoring that may be needed.
You should always contact the TB team if you experience any unexpected symptoms while taking TB medication.
Do I have to pay for TB tests or treatment?
No. TB investigations, treatment and follow-up provided through NHS TB services are free of charge.
