However, when testing the yellow fever and Dengue virus positive specimens, problems with the flavivirus cross- reactivity become obvious, resulting in specificities between 14 and 81%.
While it is possible to determine the strength and compressibility of "ideal" specimens from numerical interpretation of laboratory tests on "nominally undisturbed" specimens, the problems related to their direct use in conventional simplified design approaches for stability and settlement predictions are highlighted.
Note that sample sizes are uneven across metabolic control indicators, because there were some blood specimens with problems for computing levels of HbA1C, Triglycerdies, LDL, and HDL.
A specimen-heating problem, identified by measurements with a thermocouple, was alleviated with the use of thick, aluminum-coated grids.
With mounting evidence in favour of quantitative assessment of specimens, this problem may need addressing.
FNA specimens have unique problems, including small amount of tumor cells within the specimen, and potential specimen preparation artifacts.
FNDs allow us to observe biological specimens without photobleaching problems, and are also useful to obtain practical measurements of the imaging properties of SAX microscopy.
Problems of specimen distortion under the beam are mitigated by the use of a fast-readout direct-exposure detector [5], allowing images to be read out rapidly and shifted into register [6].
Centralization of the laboratories so that they serve several hospitals maximizes the efficiency of testing, thus reducing costs but has the disadvantage of poor communication with physicians in clinical wards and problems of specimen transfer [8].
At the same time, they replace the detergent, which often creates problems for specimen preparation, even at low concentration.
