Lactate in blood (plasma), CSF or synovial fluid
(Lactic acid)
Material: | 1 ml sodium fluoride blood or 0,5 ml sodium fluoride plasma, CSF or synovial fluid in sodium fluoride tube (glucose tube), centrifuge at once and send in the “top layer”. |
Methods: | Spektrometrie → UV- / VIS-Photometrie | Reference range | Sodium fluoride plasma: Adults and children: < 20 mg/dl (< 2,2 mmol/l) Newborns: 2,4 mg/dl – 20 mg/dl (0,26 mmol/l – 2,2 mmol/l)
CSF: 11 mg/dl – 19 mg/dl (1,2 mmol/l – 2,1 mmol/l)
Synovial fluid: < 20 mg/dl (< 2,2 mmol/l) |
Please note | Sodium fluoride plasma: Increased in case of shock, tissue hypoxia (early detection, screening and prognosis), metabolic acidosis, mitochondriopathies, performance diagnostics in athletes, type I glycogenosis (von Gierke’s disease).
CSF: Increased in the early phase of bacterial meningitis (values of > 30 mg/dl or 3,3 mmol/l indicate bacterial infection). In bacterial and non-bacterial infections however, there is a considerable overlap of values. Bacterial meningitis is unlikely when the values are below 20 mg/dl or 2,2 mmol/l.
Synovial fluid: The synovial lactate level provides a gauge of local inflammation and increases with its activity.
