Answer

Laboratory blood tests are not definitive in the diagnosis of anomalous left coronary artery arising from the pulmonary artery (ALCAPA).

Although elevation of creatine kinase (CK), MB, or troponin occurs following infarction of cardiac muscle, these tests should not be exclusively used for diagnostic purposes.
