Useful for investigating a variety of diseases involving the heart, liver, muscle, kidney, lung, and blood. Also used to differentiating heart-synthesized lactate dehydrogenase (LD) from liver and other sources, for investigating unexplained causes of LD elevations, and the detection of macro-LD.

Useful for monitoring serum concentration of lamotrigine, assessing compliance, and adjusting lamotrigine dose in patients receiving other anticonvulsant drugs which interact pharmacokinetically with lamotrigine.
Useful in the investigation of a variety of diseases involving the heart, liver, muscle, kidney, lung, and blood. Also used to monitor changes in tumor burden after chemotherapy.
Useful for monitoring serum concentration of levetiracetam, particularly in patients with renal disease, assessing compliance, and assessing potential toxicity.
Useful for assessment and management of a patient's risk for atherosclerotic cardiovascular disease, and for identifying residual risk that may be present in some patients on cholesterol targeting treatment.

Useful for confirming or excluding the presence of lupus anticoagulant (LAC), distinguishing LAC from specific coagulation factor inhibitors and nonspecific inhibitors, and investigating a prolonged activated thromboplastin time (especially when combined with other coagulation studies). It is not useful for the detection of antiphospholipid antibodies that do not affect coagulation tests, we recommend separate testing for serum phospholipid (cardiolipin) antibodies.
