Q: Which test is more reliable in acute alcoholic pancreatitis? (select one)
In non-alcoholic acute pancreatitis serum amylase usually rises more than three times the normal but chronic alcoholic patients may not be able to produce this elevation as their parenchyma lacks both in quality as well as in quantity. Also, amylase has a short half-life, less parenchyma for it's production and patients with ETOH abuse history tends to present more than 24 hours after the attack.
Serum lipase is specific to pancreas, has a longer half-life in days and requires less parenchyma to get produce.
