Tuberculosis significantly lowers blood sodium level from the normal range of (135 - 145mEq/L), increases potassium level from the normal range of (3.5 - 5.0 mEq/L), increases blood creatinine level from the normal range of (0.6 - 1.2mg/dL) and increases Blood Urea Nitrogen (BUN) from the normal range of( 7 - 20mg/dl).
Treatment is by the administration of antibiotics like Isoniazid and ethambutol to combat and eliminate the mycobacterium tuberculosis.
