Gmp terms

Acceptance criteria: the product specifications and acceptance/rejection criteria, such as acceptable quality level and unacceptable quality level, with an associated sampling plan, that are necessary for making a decision to accept or reject a lot or batch (or any other convenient subgroups of manufactured units).
Action Levels: microbiological levels in the controlled environment, specified in the standard operating procedures, which when exceeded should trigger an investigation and a corrective action based on the investigation.
Air Sampler: devices or equipment used to sample a measured amount of air in a specified time to determine the particulate or microbiological status of air in the controlled environment.
Airborne Particulate Count (or total particulate count): particles detected are 0.3 um, 0.5 um, and larger. when a number of particles is specified, it is the maximum allowable number of particles per cubic meter of air (or per cubic foot of air).
Airborne viable particulate count (or total airborne aerobic microbial count): when a number of microorganisms is specified, it is the maximum number of colony-forming units (cfu) per cubic meter of air (or per cubic foot of air) that is associated with a cleanliness class of controlled environment based on the airborne particulate count.
Airlock : an enclosed space with two or more doors, which is interposed between two or more rooms, e.g., of differing classes of cleanliness. for the purpose of controlling the airflow between those rooms when they need to be entered. an airlock is designed for and used by either people or goods. (27)
Alert Levels : microbial levels, specified in the standard operating procedures, which when exceeded should result in an investigation to ensure that the process is still within control. alert levels are specific for a given facility and are established on the basis of baseline developed under an environmental monitoring program. these alert levels can be modified depending on the trend analysis done in the monitoring program. alert levels are always lower than action levels.
Aseptic Processing: a mode of processing pharmaceutical and medical products that involves the separate sterilization of the product and of the package (containers/closures or packaging material for medical devices) and the transfer of the product into the container and its closure under microbiologic critically controlled conditions.
Audit: inspection of facilities, functions, or records.
Authorized person: a person responsible for the release of batches of finished product for sale. in certain countries the batch documentation of a batch of finished product must be signed by an authorized person from the production department and the batch test results by an authorized person from the quality control department for batch release.
batch (or lot): a defined quantity of starting material, packaging material or product processed in a single process or series of processes so that it could he expected to be homogeneous. in the case of continuous manufacture, the batch must correspond to a defined fraction of the production, characterized by its intended homogeneity. it may sometimes be necessary to divide a batch into a number of sub-batches, which are later brought together to form a final homogeneous batch.
Batch Number (or lot number): a distinctive combination of numbers and/or letters which specifically identifies a batch on the labels, the batch records, thecertificates of analysis, etc.
Batch Numbering System: standard operating procedure describing the details of the batch numbering.
Batch Records: all documents associated with the manufacture of a batch of bulk product or finished product. they provide a history of each batch of product and of all circumstances pertinent to the quality of the final product. (27) (in reference 27, batch records for production are called “batch processing records” and for the packaging operations “batch packaging records” )
Bioburden: total number of microorganisms detected in or on an article prior to a sterilization treatment.
Biogenerator: a contained system, such as a fermentor, into which biological agents are introduced along with other materials so as to effect their multiplication or there production of other substances by reaction with the other materials. biogenerators are generally fitted with devices for regulation, control, connection, material addition and material withdrawal.

Containment: the action of confining a biological agent or other entity within a defined space. primary containment: a system of containment which prevents the escape of a biological agent into the immediate working environment. it involves the use of closed containers or safety biological cabinets along with secure operating procedures.
Secondary Containment: a system of containment which prevents the escape of a biological agent into the external environment or into other working areas. it involves the use of rooms with specially designed air handling, the existence of airlocks and/or sterilizers for the exit of materials and secure operating procedures. in many cases it may add to the effectiveness of primary containment.
Control: controls resemble the unknown in composition and are assayed at the same time under the same test conditions by the same method. the results of these tests are used in calculating the mean and standard deviation of the test. controls are used to measure accuracy.
