83605 Lactate (lactic acid)
Additional Information
Use: Measurements of lactic acid are useful
in the diagnosis and treatment of lactic acidosis (abnormally
high
acidity in the blood). Typically, patients with lactic
acidosis and congestive heart failure or severe anemia show
poor
tissue oxygenation (hypoxia). Patients with lactic
acidosis
and diabetes mellitus, renal failure or liver disease usually
do
not show evidence of hypoxia.
Specimen Transport Temperature and Stability
RRMC: Transport plasma to Chemistry on ice. CRITICAL: Sample must be spun and aliquoted within 15 minutes of collection.
Once spun and aliquoted within 15 minutes of collection the plasma is stable when stored at 15-25°C for up to 8 hours or at 2-8°C for up to 14 days.
CSF samples are stable at 2-8°C for up to 24 hours.
