The phrase "as primary screening" is correct and usable in written English.
It can be used in contexts where you are discussing a method or process that serves as the initial evaluation or assessment of something.
Example: "The results of the initial tests will be used as primary screening to determine which candidates proceed to the next phase."
Alternatives: "as initial assessment" or "as first evaluation".
The efficacy of faecal occult blood test as primary screening for colorectal cancer has been demonstrated.
Whether the current screening practice needs to be changed in which iPTH levels be used as primary screening tool will depend on whether isolated iPTH level increases have negative consequences on human health, as some data, in particular with regard to mood (Hoogendijk et al. 2008), cognition (Jorde et al. 2006; Roman et al. 2005), and cardiovascular disease (Hagstrom et al. 2009), suggest.
Finally, colonoscopy capacity is a limiting factor for its widespread use as primary screening test.
This is especially important in healthcare centers that serve as primary screening points for further treatment.
HPV testing as primary screening seems to be highly recommended to improve overall sensitivity of screening and in particular for the optimization of adenocarcinoma diagnosis [ 20].
It is an attractive technique to use as primary screening, but the next step should be to validate the results in other models.
Therefore, forage quality assays used in ruminant nutrition are also potentially useful as primary screens in evaluating biofeedstock conversion potential.
However, we favour using these microarray data as primary screens of gene expression followed by subsequent confirmation by gene-specific RT-PCR studies.
In addition, two more compounds not annotated as GCs were scored as primary screen hits: pregnenolone, a key intermediate in the biosynthesis of GCs, and the MR antagonist spironolactone.
In conclusion, the mLAMP described here can potentially facilitate simultaneous monitoring of Salmonella and Shigella in a large number of food samples, which could be used as a primary screening method and as a supplement to classical detection method.
Fragment-based hits are typically weak inhibitors (10μM-mM), and therefore need to be screened at higher concentration using very sensitive biophysical detection techniques such as protein crystallography and NMR as the primary screening techniques, rather than bioassays.
