Sample Storage and Stability
•
Samples should not be frozen at -20°C.
•
Samples stored at -25°C for 1 month showed a – 14% bias.
•
Samples stored at -80°C for 3 months showed a 2% bias.
Reagent Storage and Stability
•
Do not freeze reagents.
•
Protect reagents from light.
Calibrator Storage and Stability
•
Do not refreeze calibrator.
•
The calibrator should not be frozen at -20°C.
•
The calibrator concentration changes with each lot
number and is listed on the label.
•
The calibrator is reconstituted with 1 mL DI water,
allowed to stand for 5 minutes, and swirled until
dissolved. Due to the low volume of the calibrator (1 mL),
a 1 mL Class A volumetric pipette should be used.
•
Do not shake the calibrator. Shaking can cause calibration
inconsistencies due to bubbles in the vial.
•
The calibrator is traceable to the National Reference
System for Cholesterol, NRS/CHOL.
•
The calibrator is supplied with the reagent, and cannot be
ordered separately.
