Most regulatory agencies do require CVC to be preformed at least twice a year.
Because different inspectors interpret these regulations differently there is often confusion for the customer. We also try to explain it is good lab practice to run this type kit for calibration verification, linearity checks and reportable range verification. All RNA products have FDA 510k certification. The above agencies do not recommend any specific products, but be assured ours will meet any of their guidelines for calibration verification and linearity checks. This proficiency material, although necessary, is different from the CVC kit RNA offers.
