Specimen A specimen refers to a sample of biological material, such as blood, urine, or tissue, that is collected from a patient for laboratory analysis. Specimens are crucial for diagnosing medical conditions and monitoring treatment effectiveness. Proper collection, handling, and transport of specimens are essential to ensure accurate test results.

Collection Collection is the process of obtaining a specimen from a patient for testing. It involves following specific protocols to prevent contamination and ensure the integrity of the sample. Different types of specimens require different collection methods, such as venipuncture for blood collection or clean-catch urine collection for urine specimens.

Procedure A procedure is a series of steps or actions that need to be followed to collect a specimen correctly. Understanding and adhering to proper collection procedures are essential to avoid errors and ensure the reliability of test results. Each type of specimen has its own set of procedures that must be carefully followed.

Phlebotomy Phlebotomy is the practice of drawing blood from a patient for diagnostic testing or blood donation. Phlebotomists are trained professionals who specialize in venipuncture techniques to collect blood specimens safely and efficiently. Proper phlebotomy techniques are crucial for obtaining high-quality blood samples.

Labeling Labeling is the process of identifying specimens with patient information, such as name, date of birth, and medical record number.
