What does lactate mean in a cerebrospinal analysis?
Lactate in cerebrospinal fluid analysis can indicate a variety of conditions, such as bacterial meningitis, brain tissue injury, or metabolic disorders. Elevated levels of lactate can suggest a disruption in normal cellular metabolism or oxygen supply, which can be valuable for diagnosing different neurological conditions.
What is cerebrospinal fluid analysis?
The procedure to remove cerebrospinal fluid is called a lumbar puncture, or spinal tap, because the area of the spinal column used to obtain the sample is in the lumbar spine, or lower section of the back.
What does the abbreviation LDH mean?
LDH stands for lactate dehydrogenase, an enzyme found in the body that plays a role in the conversion of lactate to pyruvate during energy production. Elevated levels of LDH in the blood can indicate tissue damage or certain medical conditions.
What is lactate dehydrogenase?
Lactate dehydrogenase is an enzyme present in the body that plays a key role in converting lactate to pyruvate during energy production. It is found in various tissues, including the heart, liver, muscles, and red blood cells. Elevated levels of lactate dehydrogenase in the blood can indicate tissue damage or disease.
Why is lactate dehydrogenase elevated in viral hepatitis?
Lactate dehydrogenase (LDH) is elevated in viral hepatitis due to liver cell damage and necrosis caused by the viral infection. As hepatocytes are destroyed, LDH, which is normally found in these cells, leaks into the bloodstream, leading to increased serum levels. Additionally, the inflammatory response during viral hepatitis can further contribute to cellular damage and the release of LDH. Therefore, elevated LDH levels can serve as a marker of liver injury in this condition.
What does high lactate level mean?
A high lactate level in the blood typically indicates that the body is undergoing anaerobic metabolism, often due to insufficient oxygen supply to tissues. This can result from conditions such as sepsis, shock, or intense exercise. Elevated lactate levels can signify metabolic acidosis and may require further investigation to determine the underlying cause. It's important for healthcare providers to assess the clinical context when interpreting high lactate levels.
What is the most sensitive indicator of hypoperfusion?
Lactate levels are typically considered the most sensitive indicator of hypoperfusion. Elevated lactate levels can indicate inadequate tissue perfusion and oxygen delivery, often seen in conditions like sepsis, shock, or heart failure. Monitoring lactate levels can help in assessing the severity of hypoperfusion and guiding treatment.
When Muscle lactate increase?
Muscle lactate increases primarily during intense exercise when the demand for energy exceeds the oxygen supply, leading to anaerobic metabolism. This process converts glucose to lactate, allowing for continued ATP production despite low oxygen levels. Elevated lactate levels can cause muscle fatigue and discomfort, signaling that the body is working at high intensity. Once the exercise intensity decreases or oxygen becomes available, lactate levels typically return to normal as it is cleared from the muscles and converted back to glucose or used as fuel.
What does lactate cause?
Lactate threshold is caused when lactate production exceeds lactate clearance during exercise or increasing intensity.
What is the name enzymes that catalyzes the formation of lactate during lactate fermentation?
lactate dehydrogenase

What are normal results for a cerebrospinal fluid analysis?
40-80 mg/dL glucose; 15-45 mg/dL protein; LD, 1/10 of serum level; less than 35 mg/dL lactate; 0-5/microL white blood cells (adults and children), up to 30/microL (newborns); negative Gram stain.
