Study Overview
Brief Summary
Blood will be collected after venepuncture from all patients for complete blood counts, Serum bilirubin (direct and indirect), aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, gamma glutamyl transferase, prothrombin time and INR, urea, creatinine, sodium, potassium, serum total protein and albumin, within 24 hours after admission and twice a week there after or as and when needed.
Time line for blood tests and evaluation of clinical parameters & 13C-MBT
For ALF patients:
On days 0, 1, 3, and 7
For ACLF patients:
On days 0, 7 (week 1), 14(week 2), 28 (weeks 4)
Blood tests would include:
Serum bilirubin (total and direct), aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, gamma-glutamyltransferase, Serum proteins (total and albumin), prothrombin time & international normalized ratio (INR), Serum urea and creatinine, serum electrolytes, arterial ammonia and arterial blood gas analysis.
