The phrase "a single test sample" is correct and usable in written English.
It can be used when referring to one specific instance of a sample used for testing purposes in various contexts, such as scientific experiments or quality control.
Example: "In our study, we analyzed a single test sample to determine the effectiveness of the new drug."
Alternatives: "one test specimen" or "a lone test sample".
Where the cost of testing each material individually is not justified, the combination of materials into a single test sample may be carried out.
The phosphorus diffusion profile was confirmed by a secondary ion mass spectrometry (SIMS) measurement on a single test sample.
First, only 1-dimensional probability densities are considered because the density is always only evaluated for a single test sample, which allows a 1-dimensional embedding of the feature space defined by the kernel and two data points (the support vector and the test sample).
cAAPEG adhesive hydrogel (100 μL) was applied to an immobilized tissue substrate, and a second immobilized tissue substrate was placed over the first, generating a single test sample.
The indexes allowing best classification in the leave-one-out test were further used as inputs for classifiers applied to more than a single test sample.
The MLP with the best generalization to a subset of 5 data (validation set) was chosen to estimate a single test sample (approximating the output to the closest integer to determine the estimated class).
For the single test sample, significance of the proximity to template is estimated as a nominal p-value based on a null distribution for the distance d generated by randomly resampling nA+nB genes from the N genes multiple times (default is 1,000 times).
A single test was run per sample and the ELISA plates were read at 450 nm within 30 minutes and the average of the two readings for each child calculated.
Grouping all screening samples into a single test, either RDT or conventional culture, would reduce costs [ 9].
Peter Sims, assistant professor of systems biology, and his lab developed PLATE-Seq, a platform that reduces the standard 96-well sample plate to a single test tube.
The size of samples used in this study was minus 0.2 mm, with 6 gram coal samples used in a single test.
