OIV-MA-AS1-15 Recommendations related to the recovery correction

Recovery

“The OIV recommends the following practice with regards to reporting recovery of analytical results.

• Analytical results are to be expressed on a recovery corrected basis where appropriate and relevant, and when corrected it has to be stated.
• If a result has been corrected for recovery, the method by which the recovery was taken into account should be stated. The recovery rate is to be quoted wherever possible.
• When laying down provisions for standards, it will be necessary to state whether the result obtained by a method used for analysis within conformity checks shall be expressed on a recovery-corrected basis or not.”
