Lactate Stability in Whole Blood with Glycolytic Inhibitors

Is anyone aware of a study that assesses the stability of lactate in whole blood collected in tubes containing NaF/K oxalate? The question is whether blood collected in these tubes can be sent off-site for lactate measurement (2-3 hours) without first centrifuging and separating the plasma. Every study I've found on lactate stability in the presence of anti-glycolytic stabilizers involves centrifugation within 15 minutes or less of collection. Shouldn't fluoride and oxalate inhibit glycolysis even in the presence of erythrocytes? Please share.


How do you resolve the low ambient humidity level in your laboratory (besides running the hot water)? Please share.

Glassware Cleaning - Residue Testing

I am looking for input from other organizations on the process they use to perform detergent residue testing on their glassware after cleaning. The CAP checklist item suggests using bromcresol purple, but I'm looking to see if there are other ways to perform this testing without using bromcresol purple. Please share.
