When aspartate transaminase activity in serum is increased, pyridoxal 5-phosphate addition produces more pronounced activation of post-myocardial infarct sera than of sera from patients with chronic liver disease. Possible explanations for this are considered. Routine pre-incubation of sera with pyridoxal phosphate prior to aspartate transaminase determination is recommended.
