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).
