Overview
Routine laboratory tests including arterial blood gas analysis are non-specific in patients with acute pulmonary embolism; however, in cases of suspected PE they may be ordered to rule-out secondary causes. In patients with acute PE, non-specific lab findings include: leukocytosis, elevated ESR with an elevated serum LDH and serum transaminase (especially AST or SGOT).
Laboratory Findings
- In patients with acute pulmonary embolism, routine laboratory findings are non-specific and include:
- Leukocytosis
- Elevated ESR with an elevated serum LDH and serum transaminase (especially AST or SGOT).
- Serum bilirubin levels are found to be within normal limits.
- In patients with suspected pulmonary embolism, routine laboratory tests are ordered to exclude the secondary causes of PE. These tests include:
- Complete blood count
- Erythrocyte sedimentation rate
- Coagulation studies to assess for hypercoagulable states.
- Other screening tests such as renal function tests, liver function tests and electrolyte assessment.
