What is the normal lactate level range in mmol/L?

0.2-1.0
0.5-1.5
1.6-2.5
2.6-3.5

The correct answer is: 0.5-1.5

The normal lactate level range in millimoles per liter (mmol/L) is generally accepted to be between 0.5 and 1.5. Lactate is a byproduct of anaerobic metabolism and its levels in the blood can increase under certain conditions, such as during intense exercise, shock, or other states of hypoxia. Monitoring lactate levels is important in clinical settings as it helps assess tissue perfusion and the metabolic state of patients. Elevated lactate levels can indicate a need for further investigation or intervention, particularly in critically ill patients, making understanding normal lactate levels essential for effective patient management.
