The phrase "a single specimen for" is correct and usable in written English.
It can be used when referring to one example or instance of something, often in a scientific or research context.
Example: "The researchers collected a single specimen for analysis to ensure the accuracy of their results."
Alternatives: "one sample for" or "a lone example for".
This approach is more efficient because both exogenous and endogenous exposures would be represented by a single specimen of blood, for example, and would encourage contrasts of omic profiles between diseased and healthy populations in much the same manner as GWAS (Patel et al. 2010).
Although these two species could be discriminated by their shell forms in the morphometric analyses and provided different H4/H3 sequences (except for a single specimen of O. pseudodolium from the potential hybridization area), a clear assignment to one or the other species was not possible based on the mt sequences.
The sequence obtained for a single specimen of the race hueii (sampled in the Bale mountains, south of the Rift valley) turned out to be most closely related to G. praetermissa, even if it is quite divergent (estimated divergence time: 1.08 MYA, coinciding with the third aridification event; see Table 1, node 4).
Urine collected during hospitalization (hospital admission time point) and 30 days later (convalescent time point) from cases and a single specimen from community controls was tested for urinary arsenic by graphite furnace atomic absorption.
Only a single specimen from a single species was available for this form, therefore the form and its dimensions should be considered preliminary.
The presence of 70% difference between the minimum and maximum initial stiffness measured makes a single specimen measurement for stiffness unsuitable for frame analysis.
Qualified medical personnel obtained diagnostic respiratory specimens and a single specimen was evaluated for each child sampled within 48 hours of hospital presentation.
A single total nucleic acid preparation from a single aliquot of a single specimen is simultaneously assayed for possible detection and illumination of specimen-specific gene sequences from each of the 188 independent target pathogen gene sequencing detector tiles on the array.
