Normal lactate to pyruvate ratio
WebInterpretation An elevated lactate-to-pyruvate (L:P) ratio may indicate inherited disorders of the respiratory chain complex, tricarboxylic acid cycle disorders and pyruvate carboxylase deficiency. Respiratory chain defects usually result in L:P ratios above 20. WebSomething approximating this value can also be derived from the study of Seibert and Ebaugh 17 in severe anemia, in which no evidence of increased lactate-pyruvate ratio occurred until the ...

Webelevated throughout the study. The lactate/pyruvate ratio at shock onset was significantly higher in the non-survivors (24 [17 to 34] vs 15 [10 to 19], P=0.01) than in the survivors. All patients with cardiogenic shock had hyperlactataemia at the onset of shock and 69% had a high lactate/pyruvate ratio. Only 65% of
