What should you know about tb test and pregnancy?

Pregnancy does not make every TB test unusable, but the choice of test and the follow-up plan should be tailored to your health and stage of pregnancy. A skin test or blood test looks for an immune response; neither alone confirms active lung disease. If infection is suspected, the clinician weighs symptoms, exposure, immune health and the potential effects of delayed assessment. Tell the testing team that you are pregnant or might be pregnant.

Share your pregnancy details, expected delivery timing, medicines and any known TB exposure before testing. Attend the required reading appointment if a skin test is used. A positive result usually leads to a review for active disease, which may include a chest X-ray when clinically justified and performed with pregnancy-appropriate precautions. Never start, stop or change TB medicine without the clinician managing your pregnancy and infection risk.

Contact your maternity or medical team promptly for a persistent cough, fever, night sweats, coughing blood, chest pain or unexplained weight loss. Seek urgent help for severe breathlessness, fainting, confusion or rapidly worsening symptoms. Pregnancy can alter how illness feels, so concerning respiratory symptoms deserve assessment even if a screening result is pending.

Ask why testing is recommended, which test is planned, how pregnancy affects interpretation, and what follow-up a positive result would require. Ask how imaging would be handled if needed, which treatment options fit your situation, and how your baby will be monitored.
