All products recommend drying following sample application, which can take several hours and may delay specimen transportation and ultimately diagnostic results.
Improper handling of lab specimens delayed testing.
Since this study, we have identified several reasons for the low yield of culture, including delayed transport times for specimens and inadequate specimen collection; efforts to improve these procedures have since been implemented.
On the other hand, decrease rate of the current density on the amorphous specimen was smaller than that on the crystalline specimen, indicating the regeneration of passive film on the amorphous specimen was delayed probably because the amount of metal ions dissolved at the initial stage, i.e. the source of re-passive film, was smaller on the amorphous specimen.
Treated soil specimens were delayed for 24 h after mixing before compaction.
In these PHL, the existing first-come-first-serve testing policy and the manual methods for receiving and processing the specimens further delayed the pace of publication of confirmed cases.
Such variable results may be related to inadequate sampling of sputum (difficulty of elderly patients to produce enough sputum), delayed processing of sputum specimens, and prior antimicrobial therapy (which occurs in 50%% of the patients in the present study) [ 31].
Our approach may regularly provide physicians with forecasted bacterial infection rates to alert them about the spread of antibiotic-resistant bacterial species, especially when clinical microbiological results of patients' specimens are delayed.
Rapid processing of specimens and timely initiation of the phage assay is important: the sensitivity of the phage assay was 72% when the specimens were processed immediately and tests were performed daily [ 5] compared to the sensitivity of 29% when the processing of the specimens was delayed and the assays were run twice a week [ 9].
The main explanation may be poorer fixation of OEB compared with CNB specimens, including delayed fixation, under-fixation, and over-fixation with formalin prior to IHC analysis, because the PgR test seems to require a higher preparation quality than an ER test [ 10, 15].
