WebMar 15, 2024 · Lactate is, in general terms, a marker that anaerobic metabolism has occurred in the body. It is produced in most tissues, but mainly it’s found in muscle. In a healthy individual, it is cleared by the liver (and a little bit by the kidneys), so normal levels are typically < 1.0 mmol/L, and we start getting interested when it’s above 2-ish. WebVBG is less invasive and less painful than ABG and evidence shows there is good concordance between venous and arterial values for pH, bicarbonate ion concentration, base excess, and lactate.
