Lactate is the final product of anaerobic glucose metabolism, elevated blood concentrations will arise in cases of inappropriately high accumulation or disturbed utilisation.

Lactate analysis is useful in:-

 - Prognosis and monitoring in cases of circulatory collapse (shock) and poisoning

 - Detection of tissue hypoxia when arterial pO2 is still within the reference interval

 - Evaluation of unclear cases of metabolic acidosis, increased anion gap and comatose patients

 - Detection of foetal distress during labour and delivery
