Serum lactate in abdominal ischemia

Q: Serum lactate in abdominal ischemia has? (select one)

A) high sensitivity
B) high specificity
C) both


Answer: A

Unfortunately, despite being a known and widespread clinical entity, abdominal ischemia has no specific clinical or laboratory marker. Serum lactate continues to be the most widely used laboratory marker. It is very sensitive for abdominal ischemia (90 to 100 percent) but has low specificity (42 to 87 percent).
