Sample preparation and presentation

Good laboratory practice

According to GLP, chemicals, reagents and solutions should be labelled to indicate identity (with concentration if appropriate), expiry date and specific storage instructions. Information concerning source, preparation date and stability should be available. The expiry date may be extended on the basis of documented evaluation or analysis. Records, including test-item and reference item characterisation, date of receipt, expiry date, and quantities received and used in studies should be maintained. Handling, sampling and storage procedures should be identified in order that the homogeneity and stability are assured, and that contamination and mix-up are precluded. Storage containers should carry information on identity, expiry date and specific storage instructions. The stability of test and reference items under storage and test conditions should be known for all studies.
