Gastric (aspirate) washing		A procedure performed to collect swallowed sputum, which is then tested for TB.

It is done by introducing a small, smooth rubber tube into the stomach so that contents of the stomach can be removed.
Good Clinical Practices (GCP)		An FDA and international ethical and scientific quality standard for designing, conducting, recording and reporting trials that involve the participation of human subjects. GCP provides assurance that the data and reported results are credible and accurate and that the rights, integrity and confidentiality of trial subjects are protected.
Good Laboratory Practices (GLP)		Embodies a set of principles that provides a framework within which laboratory studies are planned, performed, monitored, recorded, reported and archived. GLP helps assure regulatory authorities that the data submitted are a true reflection of the results obtained during the study and can therefore be relied upon when making risk/safety assessments.
Good Manufacturing Practices (GMP) or current Good Manufacturing Practice (cGmp)		A set of standards for the biomedical products industry aimed at ensuring that products are consistently manufactured to a quality appropriate to their intended use.
