Lactate - Plasma

The sample for the CSF test is collected through a lumbar puncture or spinal tap. The blood sample for the plasma test is collected through a standard venipuncture.

The test measures the level of lactate in the CSF and plasma. High levels can indicate conditions causing a lack of oxygen in body tissues or brain, like shock, severe infections, or specific neurological disorders.

These results can guide healthcare professionals in diagnosing the underlying cause of symptoms, managing the disease process, and monitoring the effectiveness of treatments.

The frequency of this test depends on the patient's condition. It may be repeated as necessary to monitor changes in a critically ill patient or a patient with a significant neurological condition.

Normal values can vary depending on the lab but typically range from 0.5 to 2.2 millimoles per liter (mmol/L) for plasma and 1.2 to 2.1 mmol/L for CSF.

Patients should follow any advice or recommendations given by their doctor based on the test results. After a lumbar puncture, rest and avoidance of strenuous activities are often advised.

Many factors can affect lactate levels, including high-intensity exercise, certain medications, liver disease, conditions that cause a lack of oxygen in body tissues, and the process of the lumbar puncture itself.

In case of abnormal results, a consultation with a neurologist or a relevant specialist (such as an internist, cardiologist, or endocrinologist) may be necessary for accurate diagnosis and treatment planning.

The blood draw for the plasma test may cause minor discomfort. The lumbar puncture for the CSF test might cause discomfort or pressure in the lower back.

Yes, elevated lactate levels in blood can indicate sepsis, while high levels in CSF may suggest meningitis.

The results typically come back within 1 to 2 days.

Risks associated with blood draw are minimal, while lumbar puncture risks include headache, infection, or bleeding.

Yes, high levels of lactate in the CSF and plasma can be indicative of mitochondrial disorders affecting the brain and body’s energy production.

In summary, the Lactate - CSF and Plasma test is an essential tool in diagnosing and monitoring a range of medical conditions. By measuring lactate levels, healthcare professionals can obtain insights into the body and brain's metabolic processes, and identify abnormalities. Whether undergoing this test for diagnostic or monitoring purposes, it is crucial to understand the procedure and to follow the healthcare professional's instructions and recommendations based on the results.
