Overview
Laboratory findings consistent with the diagnosis of tumor lysis syndrome include high serum uric acid, potassium, phosphorus, and lactate dehydrogenase. Another laboratory abnormality is low calcium.[1]
Laboratory Findings
Laboratory findings consistent with the diagnosis of tumor lysis syndrome include:[1][2]
- Blood:
- Hyperuricemia ≥ 476 μmol/l
- Hyperphosphatemia ≥ 2·1 mmol/l (children), x ≥1·45 mmol/l (adults)
- Hyperkalemia ≥ 6·0 mmol/l
- Hypocalcemia ≤ 1·75 mmol/l
- Creatinine ≥1.5 x ULN
- Lactate dehydrogenase > ULN
- Metabolic acidosis
- Low urine output
- Uric acid crystals or amorphous urates
- High uric acid-creatinine ratio > 1.0
