AC2B is the standard protocol for acetate determination. If the acetate concentration of a sample is expected to be higher than 2.3 g/L (38.9 mmol/L), then protocol AC2D should be used (same protocol with preset 1:10 sample predilution). Results higher than the valid measuring range will be flagged and a rerun with an automatic 1:10 predilution will be recommended by the software.

Other suitable control material can be used in addition. Control intervals and acceptance limits should be adapted to each laboratory's individual requirements. If values do not fall within the defined limits, corrective measures and recalibration are required

"Value": "Acetate (or acetic acid) is converted to acetyl-CoA using ATP and CoA in presence of acetate kinase (AK) and phosphotransacetylase (PTA). Acetyl-CoA reacts with oxaloacetate in presence of citrate synthase (CS) to citrate. The required oxaloacetate is produced by oxidation of L-malate with NAD+ in presence of L-malate dehydrogenase (MDH), but only if the oxaloacetate is immediately consumed by acetyl-CoA, otherwise the reverse reaction of oxaloacetate to L-malate would be the dominant direction. The NADH generated in the oxaloacetate production is measured by increase in absorbance at 340 nm, and this relates to the formation of Acetyl-CoA which directly depends on the acetate concentration of the sample.

"Value": "Measuring Range Acetate concentration can be determined in following range:
AC2B: 15 - 2300 mg/L (0.25 - 38.8 mmol/L)
AC2D: 1.5 - 23 g/L (2.5 - 388 mmol/L), up to 230 g/L (3.88 mol/L) with automatic predilution
Conversion Factors Conversion factors for acetate concentration:
1 mmol/L = 59.05 mg/L
1 g/L = 16.93 mmol/L
Traceability This method has been standardized against an independent photometric ezymatic assay.
Precision Representative performance data on Cedex Bio Analyzers are shown. Results obtained in individual laboratories may differ. Precision was determined in samples of three concentration levels. Coefficients of variation (CV) were calculate in-run precision (n=21) and inter-run precision (on 10 days).
