Re: Question for RH on lactate/pyruvate ratio

[Guest guest]

If the lactate and pyruvate blood test results are shown in the same

units, the lactate/pyruvate ratio should just be:

(lactate blood test result) divided by (pyruvate blood test result)

At one point I had 4.8 for my lactate, and 0.04 for my pyruvate. That

would yield a lactate/pyruvate ratio of 120 (= 4.8/0.04), much higher

than the stated normal of 20 or less, yet both values were normal on

the lab's scale.

Here's a link about lactate/pyruvate ratio:
