The phrase "a sample type" is correct and usable in written English.
It can be used when referring to a specific category or classification of a sample in various contexts, such as research, statistics, or product descriptions.
Example: "In our study, we focused on a sample type that included both qualitative and quantitative data."
Alternatives: "a sample category" or "a sample classification."
The heterogeneity of a sample type was presented by the mean of distances between paired samples.
For this, the average signal intensity was determined from all of the slides available for a sample type.
We measured sample heterogeneity by calculating the average Pearson dissimilarity distance between paired samples within a sample type.
Pooling of samples should be kept to a minimum because it diminishes (or prevents) the ability to assess biological variation within a sample type.
For this reason, it seems that plasma CE is not as robust a sample type in which to assess EPA plus DHA status.
Circulating DNA in cell-free plasma 30) has received increasing levels of attention as a sample type for developing noninvasive prenatal 31) and oncology 32) diagnostics.
The basic aims have been to develop methods to find out what is in a sample (typing), how pathogenic it is, and what the antibiotic resistances profile is (phenotyping).
In principle, PCA provides the ability to identify key fragment peaks characterizing a given sample type, a survey of the point-to-point reproducibility across the sample set, and a summary of the relationship between different sample sets.
That said, comparisons for a given sample type will also share a digestion technique and may reduce variability further.
The advantage of this method is in its ability to minimize the contribution of spectral features which vary within a particular sample type and maximize the contribution of spectral features which vary among sample types.
It cannot be excluded that differences would have been found also in men in a larger sample (type II error).
