the study. Since being able to repeat studies and obtain similar results is a sine qua non<br />

of mutual acceptance of data (and, indeed, a central tenet in the scientific method), the<br />

routine procedures are described in written standard operating procedures (SOPs).<br />

Laboratories may also need to standardize certain techniques to facilitate comparison<br />

of results; here again written SOPs are an invaluable tool.<br />

3. Characterization<br />

In order to perform a study correctly, it is essential to know as much as possible<br />

about the materials used during the study. For studies to evaluate the properties of<br />

pharmaceutical compounds during the pre-clinical phase, it is a pre-requisite to have<br />

details about the test item and about the test system (often an animal or plant) to which<br />

it is administered.<br />

4. Documentation<br />

Raw Data<br />

All studies generate raw data. These are the fruits of research and represent the basis<br />

for establishing results and arriving at conclusions. The raw data must also reflect the<br />

procedures and conditions of the study.<br />

Final Report<br />

The study report, just like all other aspects of the study, is the responsibility of the<br />

study director. He/she must ensure that the contents of the report describe the study<br />

accurately. The study director is also responsible for the scientific interpretation of the<br />

results<br />

Archives<br />

Storage of records must ensure safekeeping for many years, coupled with logical and<br />

prompt retrieval.<br />

5. Quality Assurance<br />

Quality assurance (QA) as defined by GLP is a team of persons charged with<br />

assuring management that GLP compliance has been attained within the laboratory.<br />

They are organized independently of the operational and study programme, and function<br />

as witnesses to the whole pre-clinical research process.<br />
