The  GC-MS ASSAY OF BCH A N D BCK ACIDS 27 quinoxalinols are stable for at least 5 days at room temperature; after 7 days there is a decrease in the ratio of the peak area of the internal standard relative to that of each of the three keto acids. This procedure uses peak areas for quantification. If preferred, it is possible to use peak heights and obtain similar precision and accuracy. 9%), respectively, for the three acids. Reference Ranges One milliliter of human antecubital venous plasma collected after overnight fasting contains 40-80 (mean 63, RSD 25%) nmol of total branched-chain 2-keto acids, 8-16 (mean 13, RSD 22%) nmol of 3methyl-2-ketobutyrate, 20-40 (mean 31, RSD 25%) nmol of 4-methyl-2ketovalerate, and 10-30 (mean 19, RSD 32%) nmol of 3-methyl-2-ketovalerate.
