Vial	Content	Composition
PYRB	Reagent cassette, 200 tests	Reagent 1 (R1): TRIS, 230 mmol/L; sodium chloride, 80 mmol/L; lactate dehydrogenase, approximately 4,000 U/L; stabilizer; preservative; pH 7.6.
Reagent 2 (R2): Sodium bicarbonate, 20 mmol/L; NADH, 3.2 mmol/L; preservative; pH 10.2.

", "Name": "Content" }, { "Language": "English", "Value": "Measuring Range
Pyruvate concentration can be determined in following ranges:

• PYRB: 8.7 - 696 mg/L (0.1 - 8 mmol/L)
• PYRD: 87 - 6960 mg/L (1 - 80 mmol/L),

up to 69.6 g/L (0.8 mol/L) with automatic dilution

Conversion factors for pyruvate concentration

• 1 mmol/L = 87.06 mg/L
• 1 g/L = 11.49 mmol/L

Traceability
This method has been standardized against titration with HClO₄.

Precision
Representative performance data on Cedex Bio HT Analyzers are shown. Results obtained in individual laboratories may differ.
Precision was determined in samples of three concentration levels. Coefficients of variation (CV) were calculated for in-run precision (n=21) and inter-run precision (on 10 days).

	Level 1	Level 2	Level 3
Mean	0.52 mmol/L\t   (45.3 mg/L)	4.0 mmol/L\t\t  (348 mg/L)	7.0 mmol/L (609 mg/L)
CV in-run	0.8 %	0.2 %	0.2 %
CV inter-run	2.1 %	1.2 %	1.2 %
