The recovery rate is the degree of loss of the analyte in the sample analysis process. The less the loss, the higher the recovery rate. If the standard solution is 1 PPM, it is 1 mg/L, and the scale data is 0.99 mg/L. Your recovery rate is 99%. This has a close relationship with the real ingredients, indicating the correctness of the method. For example, the total inorganic chlorine content in the water is determined. The sample water contains 20 mg/L of inorganic chlorine, 100 mL of the sample water sample is taken, and 0.1 mL of the inorganic chlorine-containing standard sample with a concentration of 10 mg/mL is added, and the volume change is ignored in the measurement. When the inorganic chlorine was 2.98 mg/L, the recovery was considered to be 98%.
If the recovery is close to 100%, then the accuracy of this kit is high. Simply put, it is the ratio of added and checked out. For example, you know that A is in the sample, but the result you detected by ELISA is B, and B/A is the recovery rate. The relative recovery rate may be higher than 100%. If it is just saying "loss level", it is really incorrect. The recovery rate is not necessarily 100% or less.
For quantitative testing, it is mainly a verification of accuracy. The relative recovery rate may be higher than 100%. If it is just saying "loss level", it is actually not accurate. It should be said that the closer the recovery rate is to 100%, the higher the accuracy of this kit.
