Specimen
(Redirected from Specimens)
Specimen is a term used in the field of medicine and biology to refer to a sample of material, such as tissue, blood, or urine, that is taken from an organism or the environment and examined or tested in a laboratory. The purpose of examining a specimen is to gain information about the organism or environment from which it was taken. This information can be used for a variety of purposes, such as diagnosing disease, studying biological processes, or assessing environmental conditions.
Collection and Preparation[edit | edit source]
The collection and preparation of specimens is a critical step in the diagnostic process. The method of collection and the handling of the specimen after collection can significantly affect the results of the examination or test. For example, a blood specimen must be collected in a sterile container to prevent contamination, and it must be kept at a certain temperature until it is examined.
Types of Specimens[edit | edit source]
There are many different types of specimens that can be collected and examined. These include:
- Blood specimens: These are often used to test for diseases or conditions such as anemia, diabetes, or infections.
- Urine specimens: These can be used to test for a variety of conditions, including kidney disease, diabetes, and urinary tract infections.
- Tissue specimens: These can be taken from any part of the body and can be used to diagnose diseases such as cancer.
- Environmental specimens: These can include samples of air, water, or soil, and they can be used to assess environmental conditions or to study environmental processes.
Examination and Testing[edit | edit source]
Once a specimen has been collected and prepared, it can be examined or tested in a laboratory. The specific methods used will depend on the type of specimen and the information that is being sought. For example, a blood specimen might be examined under a microscope to count the number of different types of blood cells, or it might be tested to measure the levels of certain chemicals or substances.
