The ADA (Adenosine Deaminase) Level Test for Fluid is a laboratory investigation used to measure adenosine deaminase enzyme activity in body fluid samples.
Adenosine deaminase is an enzyme involved in immune system function. Measuring its activity in certain body fluids, particularly pleural fluid, can help healthcare professionals evaluate suspected tuberculosis (TB) and other inflammatory or infectious conditions.
Adenosine Deaminase (ADA) enzyme levels in body fluid
Elevated ADA activity
Findings that may support the evaluation of tuberculosis
Possible inflammatory or infectious conditions affecting body fluids
Sample Type: Body Fluid
Sample Quantity: As specified by the laboratory
Test Category: Laboratory – Clinical Biochemistry
No special patient preparation is generally required.
Fluid collection must be performed by a qualified healthcare professional.
Inform your doctor about current symptoms, medications and ongoing treatment.
Follow the laboratory's specific sample collection and transportation instructions.
Tuberculosis (TB), particularly pleural tuberculosis
Pleural Effusion
Certain Infectious Conditions
Inflammatory Disorders
ADA levels may help support the evaluation of tuberculosis, but an elevated result alone cannot confirm the diagnosis. Results should be interpreted alongside clinical findings, fluid analysis, microbiological testing and other investigations.
Please confirm test availability, acceptable fluid type, sample quantity and collection requirements with the laboratory before booking.
