Abdominal Aortic Aneurysm: Test and Diagnosis

Abdominal aortic aneurysm (AAA) cannot be diagnosed by laboratory parameters.

The following 1st-order laboratory parameters-obligatory laboratory tests-should nevertheless be determined.

  • Small blood count
  • Fasting glucose (fasting blood glucose)
  • Inflammatory parameters – CRP (C-reactive protein).
  • Liver parameters – alanine aminotransferase (ALT, GPT), aspartate aminotransferase (AST, GOT), glutamate dehydrogenase (GLDH) and gamma-glutamyl transferase (gamma-GT, GGT), alkaline phosphatase, bilirubin.
  • Renal parameters – urea, creatinine, cystatin C or creatinine clearance, if necessary.
  • Coagulation parameters – PTT, Quick
  • Cholesterol – total cholesterol, LDL cholesterol, HDL cholesterol.
  • Triglycerides
  • D-dimers (end product of proteolysis of fibrin) – for suspected pulmonary embolism (see also under “Pulmonary Embolism/Physical Examination” Wells score to determine the clinical probability of pulmonary embolism); negative predictive value 99.3%, thus suitable for screening!
  • Highly sensitive cardiac troponin T (hs-cTnT) or troponin I (hs-cTnI) – for suspected myocardial infarction (heart attack).
