Collection and storage of serum lactic acid samples at room temperature without deproteinization.

A new antiglycolytic agent

“…Sodium iodoacetate has been shown to inhibit glycolysis, but only for up to 2 h at room temperature. 7 Sodium £uoride slowed but did not eliminate glycolysis or the production of lactate, 8 plasma glucose values falling by as much as 0.5 mmol/ L over a 2-4-h period. 4 Recently, glyceraldehyde in combination with lithium-heparin has been found to be an alternative inhibitor of glycolysis, but this was only demonstrated for up to 8 h. 9 The aim of the present study was to examine the combination of glyceraldehyde with sodium £uoride as an inhibitor of glycolysis, and to evaluate its potential as a new antiglycolytic agent in a clinical setting.…”
