2012
The design of a straightforward one-day workflow scheme for bacterial pathogen diagnostics enables the rapid recognition of bloodstream infections. The inclusion of eight clinically relevant bacterial targets and their antibiotic resistance profiles offers the clinician an initial insight on the same day, which can lead to more adequate therapy.

This protocol describes a comprehensive hemocompatibility evaluation of blood-contacting devices using laser-cut neurovascular implants. A flow loop model with fresh, heparinized human blood is applied to mimic blood flow. After perfusion, various hematologic markers are analyzed and compared to the values gained directly after blood collection for hemocompatibility evaluation of the tested devices.

A protocol to measure peripheral blood leukocytes using a POCT card-based leukocyte analyzer is presented here. Same blood samples were tested by two automated hematology analyzers to evaluate the consistency and accuracy of the results. The results showed that the evaluated analyzer had a good correlation with the reference system.

Standardized, comprehensive and fully quantitative testing of autonomic functions is described. The autonomic tests consist of evaluation of all three major autonomic domains including cardiovagal, adrenergic and sudomotor. The severity and distribution of dysautonomia is quantitated using Composite Autonomic Severity Scores.
FAQs
The laboratory approach shapes the type of information obtained from a sample. Chemical methods can assess substances such as electrolytes, immunological methods can examine antibodies, cellular methods can characterize blood cells, and molecular methods can detect genetic material. Selecting among these approaches allows testing to address organ function, infection, inflammation, metabolism, or other clinical questions.
Because blood moves throughout the body, its contents can reflect changes associated with multiple organs and physiological processes. Measurements may therefore provide evidence about organ function, infection, inflammation, and metabolism without limiting assessment to a single type of information. This broad reach helps clinicians connect laboratory findings with diagnosis, screening, and evaluation of health.
The same general testing resource can serve different clinical purposes depending on the question being asked. Results may help identify a disease, look for evidence of a condition before or without a stated diagnosis, support treatment selection, or show whether a condition is responding to therapy. Their meaning therefore depends on the clinical context and intended use.
After collection, laboratories may examine whole blood, plasma, or serum, depending on the material relevant to the analysis. They then apply chemical, cellular, immunological, or molecular methods to measure selected components. This workflow links the sample material with the eventual result, ensuring that the analysis addresses the intended clinical or research question.
They can measure blood cells, proteins, electrolytes, hormones, antibodies, and genetic material. These results can illuminate different aspects of physiology, including organ function, infection, inflammation, and metabolism. Looking at these components gives clinical teams specific measurable findings that can support broader judgments about health, disease, and changes over time.
In research, laboratory measurements help investigate disease mechanisms and track physiological changes. Findings can also support personalized care by connecting individual results with treatment selection or response to therapy. This makes blood-based analysis useful not only for immediate clinical decisions but also for studying how diseases develop and how care may be tailored.
