- Requesting Laboratory Investigations and Specimen Identification
Every specimen container should be clearly labeled prior to sample collection in block letters with the patient's full name alongside a second identifier (e.g. ID #, National #) and the sample collection date. Do not use the container cover for labeling purposes. Each specimen should be accompanied by a request form stating clearly the patient's full name, age, gender, sample type, sample date, doctor's name and tests requested. Doctors are asked to indicate, where possible, initial or definitive diagnosis and pertinent medication.
For non-body fluid submissions, the specimen type and/or tissue site must also be indicated.
- Specimen Container
• Make sure the proper tube/container is used for the specific test requested. If in doubt, please contact our Referral Department for advice.
• Ensure that samples are sealed properly in an appropriate container using a cap/stopper (not parafilm) and that lids are well secured.
• Adhere to storage conditions, for details kindly download the Regional Referral Test List, see page 19.
• MedLabs provides specially designed Specimen Transport Bags. Please use these bags by placing specimens in the leak-proof zip-lock compartment and tick the appropriate temperature condition for transport on the bag using a permanent marker. All related documents must be enclosed in the specified pocket attached on the bag.
- Blood Specimens
• Venous Blood: Tubes and vacutainers containing anticoagulants (EDTA, Heparin, etc.) should be promptly and thoroughly, but gently mixed – DO NOT SHAKE. Haemolysed specimens produce inaccurate results.
• A complete tube volume is required.
• Heel Stick Blood: At least 2 heparinised capillaries should be drawn and immediately identified by attaching a label with the patient's full name, date and a second identifier.
• Serum samples: A minimum volume of 2ml is required.
- Urine Specimens
24hr Collection: First morning specimen on day of collection should be discarded, and all other specimens voided during a 24hr period should be collected. The urine sample should remain refrigerated until it is delivered to the laboratory. Make sure where indicated, the appropriate additive is used during the collection period. Creatinine levels will be assayed for each specimen to assess the adequacy of the collection.
- Fluid specimens
A watertight primary container as well as a secondary package is required. Make sure that an absorbent material is placed between the two packages and a sturdy outside package (wood, metal or plastic) is available.
- Slides and/or paraffin blocks
Make sure each slide / block is clearly labeled. Be sure when packing to cushion them sufficiently to reduce the possibility of breakage or crushing during transport/shipment.
- Refrigerated specimens
Place the specimen in a MedLabs sealed bag along with the cold pack in the Specimen Transport box, making sure that a paper towel is placed between them (to separate the cold pack from the specimen). Make sure that your outside package is labeled as "Refrigerated specimen – Do Not Freeze".
- Frozen specimens
Approximately 2-3 kg of dry ice must be placed around the specimen, making sure to use only plastic vials (glass may crack).
