Question: Elevated Lactic Acid

 Rajesh Rangan - Fri Feb 29, 2008 2:43 pm

Hello doctor,

We have a son diagonised with autism. Although all the test reports came normal except elevated lactic acid. We know that if a child don't co-operate for the blood test its going to affect the test results. Otherwise our son is healthy and very active and doing great. Some doctors are suggesting to go for a skin biopsy. Is this lactic acid good or bad? Please help !!!

Best Regards,

User avatar Hello Raj,

Lactic acid is a breakdown product of pyruvate when there is not enough oxygen for the pyruvate to be metabolized down the typical pathway. This can occur because of a problem in the metabolic pathway, a problem with oxygen delivery (such as due to poor tissue perfusion of blood), or most commonly a difficult or delayed collecting of blood after the tourniquet has been applied.

I would suggest repeating the lab being sure to have a free flowing blood sample. If it returns elevated again it may be worth pursuing further, with tests such as the skin biopsy. Alternatively, a skin biopsy is a very simple procedure that is quick and easy to do so you may choose to do the biopsy simply to get a definitive answer to your doctor's concerns.

Best wishes.
