Quality assurance, refers to all measures taken from manufacturing processes to selection and the use of health products, including Quality Monitoring, to ensure that the products are of the quality required for the manufacturer’s intended (registered) use.

Quality control is one part of quality assurance and is concerned with sampling, specifications and testing, and with the procurement agency’s documentation and acceptance/rejection procedures which ensure that the necessary and relevant tests are carried out and that products are not accepted for use, sale or supply until their quality has been judged to be satisfactory.

National Pharmaceutical Policy (NPP), most national health authorities have adopted their own NPP which defines the key principles and responsibilities for regulation and the quality assurance requirements for health products circulating in the country. The NPP is usually complemented by a NPP implementation plan which describes, for each policy component, the responsibilities and main activities.

National Regulatory Authority, is thenational body that administers the full spectrum of regulatory activities for pharmaceuticals and other health products, including – for example – the following functions: Registration and Marketing Authorization, Pharmacovigilance, Market Surveillance and Control, Licensing Establishments, Regulatory Inspections, Laboratory Testing (Quality control), Clinical Trials Oversight, and NRA Lot (batch) Release.

Insecticide Treated Nets (ITNs): the umbrella term for all nets treated with an insecticide, insect-growth regulator and/or synergist. The term long-lasting insecticide treated net (LLIN) is only being used for ITN classes for which physical and chemical durability have been comprehensively demonstrated against the WHO thresholds of 20 washes and 3 years of use in the field. In practice, this means that only nets treated with a pyrethroid insecticide alone are presently referred to as LLINs in the WHO Guidelines. Other nets which are now prequalified include nets containing “a pyrethroid insecticide and the synergist piperonyl butoxide” (PBO nets), and nets containing “two active ingredients” (dual ai nets).
