The phrase "assay accuracy" is correct and usable in written English.
It can be used in contexts related to testing or evaluating the precision of measurements or results in scientific or analytical settings.
Example: "The laboratory conducted a series of tests to determine the assay accuracy of the new method for measuring drug concentrations."
Alternatives: "test precision" or "measurement accuracy".
The assay accuracy was 89.2 106.4 % of the nominal values.
Assay accuracy ranged from 99.98% to 113.45%, and precision CVs were from −0.2% to 13.45%.
Importantly, this computer aided approach was instrumental for the evaluation of assay accuracy, sensitivity, specificity, and robustness during the study.
Assay accuracy, inferred from the precision and linearity data and using a spike-recovery approach, was high with a percent error (%E) range of only 3.4 20.5%E.
The analytical method of lambda-cyhalothrin in tomato was validated for tomato for parameters such as linearity, precision, specificity and assay accuracy by following guidance document on residue analytical methods (SANCO/12571/2013).
The validation results showed that assay accuracy, specificity, precision, linearity, and range were suitable for the intended use of ensuring lot-to-lot consistency of HER-2/neu expression.
The precision with which carriers and non-carriers of the undesirable single copy allele could be identified, was used to evaluate the method for various family sizes, assay strategies and assay accuracies.
The inter- and intra-assay accuracy and precision of the method ranged from −9.53%to6.75%5%.
The intra-assay accuracy and precision were estimated by analyzing six replicates containing CA at four different QC levels, that is, 20, 300, 1200, and 5000 ng/mL.
The inter-assay accuracy and precision were calculated from results obtained from quality control samples (N = 6) analysed at four concentrations (0.5, 1.1, 15 and 40 ng/mL of diclofenac in EDTA plasma representing LLOQ, QCL, QCM and QCH respectively) on three separate occasions, see Table 2.
Intra-assay accuracy and precision for iothalamic acid in urine were calculated from results obtained from 6 replicate analyses of quality controls each at 4 concentrations (1, 2, 20 and 120 μg/mL of iothalamic acid in human plasma, and 25, 40, 200 and 1200 concentrations for human urine).
