Pulmonary tuberculosis (TB) can lead to long-term complications such as fibrosis and pulmonary arterial hypertension (PAH), which significantly affect patient outcomes. This study explores the predictive value of various hematological and biochemical parameters, including hemoglobin, red blood cell count (RBC), white blood cell count (WBC), platelet count, prothrombin time/international normalized ratio (PT/INR), and liver function tests (SGOT, SGPT, bilirubin) in the prognosis of fibrosis and PAH in post-tuberculosis patients. Our analysis indicates that certain parameters, particularly hemoglobin and platelet count, could serve as valuable predictors for these conditions, aiding in early diagnosis and management.
