Packaging and sending of slides / blocks to HSL-AD

• All slides sent to us must be securely packaged in slide mailer boxes with lids taped down.
• Where possible, tape the slide boxes together to minimise movement inside the package.
• Blocks and slides must be thoroughly secured in protective material before sending i.e. blocks and slides should not be placed loose in any transport container (box) when accompanying other material.
• A new padded envelope should be used for all specimens. The reuse of envelopes is not advised as these may open during transport.
• Ensure all material (forms, slides and blocks) is in the package before sealing. (Confirm that three points of identification are present).
• Material receipt forms sent to HSL-AD must state the material sent i.e. block and slide numbers.
• Please ensure the correct address label is on the envelope.

Packages should be sent to:

HSL-Advanced Diagnostics
60 Whitfield Street
London W1T 4EU
