Sample Labelling and Despatch

After collection of the sample(s):

  1. Label sample
    All sample containers must be labelled with the following patient identifiers:
    - Patient’s name and NRIC number/Passport number
    Where applicable, the following details should also be included:
    – Time and date of collection
    – Source of sample
    – Test requested
  2. Specimen containers should be labelled at the time of collection and not deferred until a later time.
  3. Make sure the correct test request has been ordered in CPOE, or if Test Request Form is used, it has been completely and correctly filled.
  4. Samples must be placed in ziplock plastic bags with a “Biohazard” label. (Forms if used, should never be placed within the sample bag to prevent spillage onto the form or stapled onto the bag below the bag seal line.)
  5. Sample despatch
    Send sample with its accompanying request immediately for despatch to the laboratory or for collection by the Client Services transport. Specimens for Histopathology must not be sent to the laboratory by telelift. Please see Special Instructions on Sample Handling in the Histopathology Section for details. Emergency/Stat samples and samples for chromosome culture should be sent by hand, and not by telelift, immediately to the laboratory.
  6. Samples obtained using needle aspiration should be transfered to a sterile container before sending to the laboratory. If there is little material in the syringe, the needle must be removed and the syringe capped, prior to transporting to the laboratory.
  7. For glass blood culture bottles sent via the pneumatic tube system (PTS), the bottles need to be protected with a bottle holder and bubble-wrap.
