Recovery vs Concentration Charts

The recovery versus concentration charts provide OBSP recovery information for every analyte at different concentrations for every schedule OBSP assesses.

The solid black line shows 100% recovery The dashed blue line describes the median percent recovery of the data.

All data is provisional and may change if the OBSP deems necessary.

Note: If an analyte of interest is not seen in the method listing, there is no OBSP data available for that analyte
