Lactic acid - Wikipedia

History. Swedish chemist Carl Wilhelm Scheele was the first person to isolate lactic acid in 1780 from sour milk.The name reflects the lact-combining form derived from the Latin word lac, which means milk.In 1808, Jöns Jacob Berzelius discovered that lactic acid (actually L-lactate) also is produced in muscles during exertion. Its structure was established by Johannes Wislicenus in 1873.

One hundred and fifty four patients met the inclusion criteria. At 72 h, we found that the best sensitivity (95%) was when lactate was less than 1.5 mmol/l and the best specificity (89%) was present when lactate levels were greater than 2.5 mmol/l. The pH <7.25 had a sensitivity of 76% and specificity of 96%.

What Does a High Level of Lactic Acid Mean? | Reference

According to WebMD, high levels of lactic acid mean that the body's lactate threshold, also known as the anaerobic threshold, has been passed, and that lactic acid is building up in the kidneys and liver. While lactic acidosis typically causes fatigue and muscle aches, it can be potentially life-threatening.

Lactic acidosis is seen in hypoxia associated with acute cardiac or respiratory failure, shock, and acute blood loss. Blood lactate levels rise very rapidly as oxygen delivery to the peripheral tissues decreases below a critical level. An increased blood lactate level is an earlier indicator of tissue hypoxia than pH.
