Assessing Metabolic Efficiency for Comprehensive Health and Fitness Evaluation
This test measures the level of lactic acid, also known as lactate, in our blood. Lactic acid is a substance made by muscle tissue and by red blood cells, which carry oxygen from our lungs to other parts of our body. Normally, the level of lactic acid in the blood is low. Lactic acid levels rise when oxygen levels decrease. Low oxygen levels may be caused by Strenuous exercise, Heart failure, Severe infection Shock, a dangerous condition that limits blood flow to our organs and tissues. If lactic acid levels get too high, it can lead to a life-threatening condition known as lactic acidosis. A lactic acid test can help diagnose lactic acidosis before it causes serious complications.

How our test process works!
Lactate is a byproduct of anaerobic metabolism, particularly during strenuous exercise, when oxygen levels are low. A lactate test measures the level of lactate in the blood and is often used to assess conditions related to tissue hypoxia (inadequate oxygen supply) or to monitor and diagnose conditions like sepsis, heart failure, or shock.
While a lactate test itself carries minimal risks, similar to any standard blood draw, the following should be considered:
Bruising:Mild bruising may occur at the site where the blood sample is taken.
Dizziness or Fainting:Some individuals may feel lightheaded or faint after the blood draw.
Infection: Rarely, infection can occur at the puncture site.
Patients with underlying conditions: Should be closely monitored if elevated lactate levels are detected, as this may indicate a worsening of their condition.
-Venous Blood:** 0.5 to 2.2 mmol/L
- Arterial Blood:** 0.5 to 1.6 mmol/L
The normal range can vary slightly depending on the method and laboratory performing the test.
Interpretation of Results
Normal Lactate Levels: Indicate adequate oxygenation and normal aerobic metabolism.
Elevated Lactate Levels (Lactic Acidosis):May indicate conditions such as:
Sepsis: A severe infection causing widespread inflammation and tissue damage.
Shock:A state where the organs and tissues are not getting enough blood flow and oxygen.
Heart Failure:When the heart is unable to pump blood efficiently.
Liver Disease:The liver is unable to clear lactate from the blood efficiently.
Severe Hypoxia:Lack of oxygen at the tissue level, which could be due to respiratory failure, severe anemia, or carbon monoxide poisoning.
Strenuous Exercise:Temporary increase due to intense physical activity.
Very High Lactate Levels (>4 mmol/L):** Suggest a serious underlying condition, often requiring urgent medical attention.
Blood Sample:Typically, lactate levels are measured in a blood sample, either from a vein (venous blood) or an artery (arterial blood).
Plasma or Whole Blood:The sample can be taken as plasma or whole blood, depending on the laboratory's protocols.
