General requirements and labelling
Urine, CSF and plasma should be transported to us either at room temperature within 30 minutes of collection or on dry ice (-80°C). Unfrozen specimens may show "abnormalities" due to chemical, biochemical or bacterial action.
- If your laboratory has problems transporting to us on dry ice, please contact the laboratory for advice.
- Please label the sample container with the patient's name, date of birth and date, and time of collection.
- Bar codes are not a suitable substitute for this written information.
Random urine, 10 mL (minimum 2 mL), delivered immediately on ice or frozen within 2 hours of collection and transport on dry ice. No added preservative.
500µL (minimum 250µL), separate at +4°C, freeze on dry ice within 20 minutes. Storage at -80°C and transport on dry ice.
1.0 mL (minimum 250 µL), lithium heparin NOT EDTA, separate plasma at +4°C, freeze on dry ice within 20 minutes. Storage at -80°C and transport on dry ice.
>250 µL, red cell free, freeze on dry ice within 20 minutes. Storage at -80°C and transport on dry ice.
Dried blood spot
Warm the site if collecting a capillary sample and wipe away the first drop of blood. Drop the whole blood onto the circled areas of a dried blood spot card (obtained from NSW Biochemical Genetics Service or your Newborn Screening laboratory). Fill each circle in turn and do not return to top-up any spot. Allow blood to soak right through the paper. Suspend the card so that the spots do not touch any surface and air dry thoroughly for at least six hours. Label and place in an envelope inside a second envelope for mailing/transport. DO NOT PLACE IN A PLASTIC BAG.
10mL EDTA whole blood, transported to the laboratory at room temperature to arrive within 24 hours of sample collection. Do not send samples on Friday. Do not use plasma separators. Do not pack the blood in direct contact with pre-frozen ice-packs or other frozen patient specimens.
White cell pellet
Samples for white cell cystine assay require special preparation and handling before shipment to our laboratory. Please refer to these instructions.
3x2 mm diameter full-thickness skin biopsy sample, obtained under strict sterile conditions. Place in sterile tissue culture, or viral transport medium, or sterile normal saline, for temporary storage and transport to the laboratory.
Important: Do not freeze.
