 In the early 70’s FDA became aware of cases of poor laboratory
practice all over the United States.
 They discovered a lot fraudulent activities and a lot of poor lab
practices.
 Examples of some of these poor lab practices found were :
1.Equipment not been calibrated to standard form , therefore
giving wrong measurements.
2. Incorrect/inaccurate accounts of the actual lab study.
3. Inadequate test systems.
GLP was first introduced in New Zealand and Denmark in 1972, and later
in the US in 1978 in response to the Industrial Bio Test Labs scandal.

Good Laboratory Practice (GLP)
 GLP is a formal regulation created by USFDA as these
regulations were proposed on November 19,1976 and designated
as a new part of Chapter 21 of the Code of Federal
Regulations(CFR) as 21 CFR Part 58 in 1979.
organization named OECD(Organization for
 In 1981 an
Economic Cooperation and Development) produced GLP
principles that are international standards.
 GLP in OECD principles is defined as “a quality system
concerned with the organizational process and the conditions
under which non-clinical health and environmental safety studies
are planned, performed, monitored, recorded, archived and
reported”.
4

Why GLP was created?
1) GLPs were initially invoked in a reaction to malpractices in the
laboratories conducting safety experiments of medicines.
2) In the early 1970s,research laboratories in the USA found doing
work in unethical ways ,like:
 Data generation without conduct of the study.
 Falsification of the laboratory work.
 Replacement of dead animals and fabrication of test results etc.
5

Advantages of GLP
 Assures that the data are a true reflection of results obtained from
studies.
 Preclinical safety and residue safety.
 Generation of high quality and reliable test data.
 Mutual acceptance of data
 Increases public confidence.
 Shortens the time-to-market for new products.
Disadvantages of GLP
 More man power is required.
 Expensive process.
 Time consuming process. 6

Objectives of
GLP
1) GLP makes sure that the data submitted are true reflection of the
results obtained from the studies.
2) GLP makes sure that the data is traceable.
3) Promotes international acceptance of tests.
