Indications for and Interpretation of Laboratory Diagnostic Tests

  • Michele Brignole
  • David G. Benditt


The diagnostic evaluation strategy for patients with syncope of uncertain etiology (i.e., syncope that remains of uncertain nature after the initial evaluation) consists of either trying to formulate a diagnosis by employing selected laboratory tests or alternatively using a long-term monitoring approach until a syncope recurrence (or related event) can be documented (Table 7.1). In this chapter we describe the indication and the interpretation of the most commonly performed laboratory tests. In the next chapter (Chapter 8) we describe the indication and the interpretation of various systems for prolonged ECG monitoring.
