  1. ‘TLC’, total lymphocytes count; ‘QFT’, Quantiferon-Gold in Tube assay (Cellestis, Germany). QFT results for TB antigen (TB Ag) and Mitogen are provided. Cut-off for QFT positive ≥0.35 IU/ml. ‘*’ Denotes values greater than the normal range; ‘#’ Denotes values less than the normal range. Lymphopenia defined as lymphocytes < 1500 cells/mm3. ‘#’ patients with multiple co-morbids including, diabetes, chronic liver disease, chronic kidney disease, endocrine disorders (panhypo-pitutiarism, hypothyroidism, thalassemia and malignancy)
