Serum phospholipase A2

Phospholipase A2 (PLA2) is based on the distribution of Ca2 + -dependent PLA2 in the body. Can be divided into two types of secretion (PLA2-Ⅰ and PIA2-II) and cytoplasmic type (PLA2-Ⅲ and PLA2-IV). PLA2-Ⅱ is an early marker of a series of complications of severe pancreatitis. As an acute phase reaction medium, PLA2-Ⅱ is closely related to the development of severe pancreatitis. Therefore, the determination of PLA2-Ⅱ has important recognition effect on bacterial infectious necrotizing pancreatitis and severe AP complicated with multiple organ failure.
