Laboratory Specimen
Need In medicine, a laboratory specimen is a biological specimen of a medical patient's tissue, fluids, or other material used for laboratory analysis to assist in differential diagnosis or staging of a disease process. For example, to detect breast cancer, the breast tissue is biopsied, and the extracted specimen is sent to a lab for analysis and testing. This method of testing often yields extremely high levels of accuracy, with a reported 1-2% of cases having incorrect biopsy results General areas for cellular tissue extraction: * Bone marrow aspiration * Cardiac * Core * Endometrial biopsy * Endoscopic biopsy * Excisional and incisional * Fine-needle aspiration * Lymph node Preparation After extraction, all specimen containers are required to be labeled with at least two of the following identifiers (at the time of collection): patient's name, date of birth, hospital number, test request form number, accession number, or unique random number. Afterwards, all specimen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laboratories
A laboratory (; ; colloquially lab) is a facility that provides controlled conditions in which scientific or technological research, experiments, and measurement may be performed. Laboratory services are provided in a variety of settings: physicians' offices, clinics, hospitals, and regional and national referral centers. Overview The organisation and contents of laboratories are determined by the differing requirements of the specialists working within. A physics laboratory might contain a particle accelerator or vacuum chamber, while a metallurgy laboratory could have apparatus for casting or refining metals or for testing their strength. A chemist or biologist might use a wet laboratory, while a psychologist's laboratory might be a room with one-way mirrors and hidden cameras in which to observe behavior. In some laboratories, such as those commonly used by computer scientists, computers (sometimes supercomputers) are used for either simulations or the analysis of data. Scienti ...

Biology Experiments
Biology is the scientific study of life. It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. For instance, all organisms are made up of cells that process hereditary information encoded in genes, which can be transmitted to future generations. Another major theme is evolution, which explains the unity and diversity of life. Energy processing is also important to life as it allows organisms to move, grow, and reproduce. Finally, all organisms are able to regulate their own internal environments. Biologists are able to study life at multiple levels of organization, from the molecular biology of a cell to the anatomy and physiology of plants and animals, and evolution of populations.Based on definition from: Hence, there are multiple subdisciplines within biology, each defined by the nature of their research questions and the tools that they use. Like other scientists, biologists use the scientific meth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
