Overview
Lab tests for the diagnosis of unstable angina and NSTEMI include some baseline tests like complete blood count, electrolytes, serum creatinine and measurement of acute-phase proteins.
Blood Studies
Routine blood studies employed in the work up of unstable angina / NSTEMI include:
- Complete blood count - to rule out anemia, which is a potential secondary cause of UA/NSTEMI
- Electrolyte levels - especially potassium and magnesium, whose levels if reduced can be a potential cause of ventricular arrhythmias
- Serum creatinine levels - to determine the renal function if coronary revascularization procedure is considered or planned
- Acute-phase reactant proteins like interleukin 6 and serum amyloid A - have a predictive value in assessing the risk of adverse outcomes in UA
