Additional markers, such as adenosine deaminase (ADA, suggestive of tuberculosis), amylase (for suspected esophageal rupture), N-terminal prohormone of brain natriuretic peptide (NT-pro-BNP, indicating heart failure), and triglycerides (greater than 110 mg/dL in chylothorax), may be helpful [5]. The gene discussed is ADA; the disease is tuberculosis.
