    developed method had recovery rates

    What does "recovery rate" mean here? I've checked out some definition online and got no clue there.


    -------------------
    Development of an HPLC-Based Method for the Detection of Aflatoxins in Pu-erh Tea [2015]

    Aflatoxins are toxic metabolites produced by fungi. The objective of this study was to develop an HPLC method to detect the presence of aflatoxins in Pu-erh tea. The developed method had recovery rates of 81.0290.69%. The results revealed that Pu-erh teas from Yunnan, China, contained aflatoxins, especially AFB1 (8.333 μg/kg in raw and 20.149 μg/kg in ripe tea). All tea samples had aflatoxin levels below the national maximum permissible limits; however, the tea samples had higher aflatoxin levels than those allowed in the European Union, the USA, and Japan. The presence of aflatoxins in Pu-erh tea hinders its international marketability.

    I think only the author of the paper would know what the term means and should have provided the explanation at the outset, especially for the uninitiated.
    I am not a teacher or a native speaker.

    Could it be describing the accuracy of the method- it managed to recover 80-90% of the aflatoxins?
