Samples – requests and labelling

South West London Pathology (SWLP) has a sample request and labelling policy which describes how requests for pathology investigations should be made and accompanying samples labelled.

These robust arrangements are to ensure that any requests or specimens sent to any of our laboratories are correct and accurately labelled.

Accurate identification of the patient will ensure that the request will be processed quickly, sample analysed in a timely manner and an accurate and informative report issued.

This information is targeted at all users of our pathology services including trust, primary, secondary and tertiary referrals and also applies to specimens and requests sent as part of the Antenatal Screening Program.

Some departments may require additional information or may allow for some exceptions and this information is referred to on this site or links to additional documents will be provided.
