2022
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.

Source: Roberto Leon, Department of Civil and Environmental Engineering, Virginia Tech, Blacksburg, VA Wood is a ubiquitous material that has been used in construction from the earliest times. Wood is a renewable, sustainable material with great aesthetic value. Today, there are probably more buildings constructed with wood than any other structural material. Many of these buildings are singlefamily residences, but many larger apartment buildings, as well as commercial and industrial buildings,...

2023
An interdisciplinary team includes many healthcare professionals working together and utilizing their skills, knowledge, and expertise to provide holistic and quality patient care. Physicians The physician's primary responsibility is to diagnose illness and direct the medical or surgical treatment of the condition. The authority to admit patients to a healthcare agency or institution and practice care within that setting is granted to physicians by the healthcare agency or institution itself.

Mice (Mus musculus) are small rodents that breed and sexually mature quickly, making them perfectly suited to generating large animal colonies for biological research. As compared to other mammalian species, mice are simple and inexpensive to maintain in the laboratory. Nevertheless, mouse colonies do have specific husbandry needs that are critical to preserving animal health and safety as well as experimental reproducibility. This video demonstrates standard practices that ensure mice are...
FAQs
The biological target shapes what a point-of-care test can report. Microbial-antigen assays seek evidence associated with the infectious agent, antibody assays measure a host response, and nucleic-acid systems detect pathogen genetic material. Choosing among these targets matters because the result represents different biological information, so test selection should match the clinical or surveillance question.
These formats support different detection strategies within point-of-care testing. Lateral-flow immunoassays and biosensors can be used to detect microbial antigens or host antibodies, while compact amplification systems are suited to nucleic-acid detection. The distinction helps explain why devices vary in their targets, specimen requirements, and potential clinical or surveillance applications.
Analytical sensitivity, specificity, and specimen quality are central determinants of result reliability. Sensitivity affects whether the test detects the target, specificity affects how selectively it identifies that target, and poor-quality blood, saliva, or swab specimens can undermine performance. Appropriate interpretation must consider these factors rather than treating every rapid result as equally informative.
Selection connects the diagnostic question with both the specimen and the detection method. Blood, saliva, and swabs may be used, while the device may employ an immunoassay, biosensor, or compact nucleic-acid system. Matching these choices to the intended microbial or host target supports relevant results and helps the test address clinical, infection-control, or surveillance needs.
Its main value appears when results must support a rapid decision close to the patient. In infection-related settings, testing can contribute to screening, treatment selection, infection control, and disease surveillance. Results may be available within minutes to hours, allowing these activities to proceed without relying exclusively on the timing of centralized laboratory analysis.
Depending on the assay, a result can indicate the presence of a microbial antigen, a host antibody, or nucleic-acid material. These outputs answer different questions about the infection-related sample and therefore require appropriate interpretation. Their practical value lies in connecting the detected signal with decisions about screening, treatment, infection control, or surveillance.
Ongoing development emphasizes multiplex detection and improved access in resource-limited settings. Multiplex systems could address more than one target within a testing approach, while greater accessibility could extend diagnostic support beyond settings with extensive laboratory infrastructure. Together, these directions are relevant to broader screening, infection monitoring, and disease-surveillance strategies.
