Cy-TB Skin Test - Kerala

July 26 , 2025 12 hrs 0 min 36 0
  • Kerala has introduced a new intradermal test called Cy-TB for detecting and treating tuberculosis (TB) infection.
  • TB infection is different from active TB disease.
  • A person with TB infection harbours the organism causing TB infection (Mycobacterium tuberculosis) in the body.
  • But the organism remains dormant or inactive in the body and the person neither has any TB symptoms nor is he/she contagious.
  • However, if left untreated, 5-10% of these people will progress to developing active TB disease when the body’s immune system weakens, allowing the TB bacteria to flare up.
