The phrase "assay failure" is correct and usable in written English.
It can be used in contexts related to scientific testing, particularly in laboratories or research settings, to indicate that a test or analysis did not yield the expected results.
Example: "The results of the experiment were inconclusive due to an assay failure, prompting the team to repeat the tests."
Alternatives: "test failure" or "analysis failure".
The SVC was more prone to assay failure than RVC.
Reasons for assay failure included unsuccessful bisulfite conversion/PCR (6%; 9/153), and inability to classify due to assay QC failure (24%; 37/153) (Fig. 4e).
Compared with a haploid reference sequence, there are four possible outcomes of SNP array genotyping: homozygous for the reference allele; homozygous for the variant (non-reference) allele; heterozygous; and assay failure.
QC measures for CpG locus-specific assay failure were established; up to 6 failed CpGs per sample were tolerated within the multiply-redundant signature/classifier without impacting performance and this was the case for 101/106 validation cohort samples (Supplementary Figs 3 and 4).
Total sample numbers can differ due to lack of human material or assay failure BD blood donors, CF cystic fibrosis, ED eye disease.
Total sample numbers can differ due to lack of human material or assay failure aROC: CD <18 years vs ED bROC: CD ≥18 years vs BD cROC: CD vs ED + BD.
Furthermore some known common variants were poorly tagged, because of tSNP assay failure.
In total, 155 samples were selected for the inter-laboratory comparison study allowing for a 3% possible assay failure rate as observed in the pilot study.
The unique platform significantly reduced the probability of assay failure (under 1%), which is of critical importance in practical use when dealing with clinically rare samples.
A negative response to the positive control, PHA, was used to determine assay failure, in which case the result was discounted from the data set.
For 11 of 179 (6.1%) tested samples, the fraction of mutant transcripts was estimated by two RT-PCR reactions because of assay failure in one of the three replicates.
