1. Is there anything I can do to decrease my lactate levels?
2. Why would my doctor choose to measure arterial lactate rather than venous lactate?
1. Is there anything I can do to decrease my lactate levels?
Generally, no. However, if your elevated lactate levels are due to an underlying condition that can be addressed, such as uncontrolled diabetes or a substance that can be avoided, such as ethanol, then you may be able to lower them. If you have been diagnosed with a condition, such as a metabolic disorder, following your prescribed treatment regimen should control your lactate levels. If the increase is due to a temporary condition, such as shock or infection, then they will usually return to normal after the condition has been resolved.
2. Why would my doctor choose to measure arterial lactate rather than venous lactate?
Lactate measurements from arterial blood are thought to be more accurate and, because a tourniquet is not used, they are not generally affected by the collection process. Your doctor may order an arterial lactate for these reasons or because arterial blood gases are also being collected (and the same sample can be used). When other arterial blood tests are not being ordered, the doctor may order a venous lactate because it gives him an adequate evaluation of your lactate concentrations and because the collection process is not as uncomfortable.
