The phrase "assayed at the completion" is correct and usable in written English.
It can be used in contexts where you are discussing the evaluation or testing of something upon its completion.
Example: "The results of the experiment were assayed at the completion to determine their accuracy and reliability."
Alternatives: "evaluated upon completion" or "tested at the end".
However, in agreement with the findings from our study, over half of the patients in this study had a positive IFN-γ ELISpot assay result at the completion of anti-tuberculous treatment.
In a more recent study in French children, Hermann et al reported a decrease in the magnitude of IFN-γ responses (measured using QuantiFERON-TB Gold In Tube (QFT-GIT)) during anti-tuberculous treatment but found no difference in the proportion of children that had a positive assay result at the completion of treatment compared to baseline [ 32].
The clinical usefulness of serial IFN-γ ELISpot measurements for assessing a successful curative response to anti-tuberculous treatment in this setting is, however, questionable as almost half of the children had a positive IFN-γ ELISpot assay result at the completion of anti-tuberculous treatment.
Of the studies that have reported serial IGRA (whole blood or IFN-γ ELISpot assay) measurements prior to, during or at the completion of treatment of active TB disease in adults, four have shown an increase [ 23, 24, 29, 30] and six a decrease [ 20, 22, 25- 27, 35] in the magnitude of the IFN-γ responses.
Students completed surveys at the completion of each case.
At the completion of the assay, OD450 was read on a SpectraMax M2 plate reading spectrophotometer (Molecular Devices).
Mites were incubated in a 28°C humidified incubator and observed microscopically within the first 15 30 mins, hourly thereafter up to 6 hours, and again at the completion of the assay (24 hrs).
At the completion of the assay, cells were examined by fluorescence and phase-contrast microscopy to confirm that fluorescent areas corresponded to attached bacteria.
At the completion of the assay, supernatants were harvested, and IL-8 expression was evaluated by an enzyme-linked immunosorbent assay (ELISA), using Human IL-8 Ready-SET-Go!® ELISA Set (eBioscience, USA).
At the completion of the assay, plates were thawed and 200 μl cell lysis buffer (10 m M Tris HCl pH 8.0 containing 2.5 m M EDTA, 1% Triton X-100) containing SYBR Green I (1 : 4000 v/v) were added to the wells.
