The Adenosine Deaminase (ADA) test is used to diagnose conditions such as tuberculosis (TB) and evaluate lymphocytic pleural effusions, aiding in the differentiation of various diseases causing pleural fluid accumulation.
What does ADA positive mean?
ADA positive indicates elevated levels of Adenosine Deaminase, suggesting an increased immune response. In the context of TB diagnosis, a positive ADA result is indicative of Mycobacterium tuberculosis infection or other granulomatous diseases.
What is ADA level in TB?
ADA levels in TB are typically elevated. A threshold level (usually >40 U/L) is often considered diagnostic, aiding in the differentiation of TB from non-TB causes of pleural effusion.
What happens if ADA is high?
High ADA levels suggest an active cell-mediated immune response. In TB, this indicates an increased likelihood of Mycobacterium tuberculosis infection. Elevated ADA may contribute to inflammation, leading to symptoms like fever and cough.
