How do you measure lactic acid?

Lactic acid can be measured using various methods, including enzyme-based colorimetric assays, which involve the reaction of lactic acid with specific enzymes to produce a measurable color change. Another common technique is high-performance liquid chromatography (HPLC), which separates and quantifies lactic acid in a sample. Additionally, biOSensors that utilize electrodes can provide real-time measurements of lactic acid levels in biological samples. Each method has its advantages depending on the required sensitivity and specificity.
