Sample Requirements

(Exceptions shown on previous page)

If you have problems obtaining dry ice to transport a sample, please contact the laboratory for advice.

Urine

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.

Serum

500µL (minimum 250µL), separate at +4°C, freeze on dry ice within 20 minutes. Storage at -80°C and transport on dry ice.

Plasma

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.

CSF

>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.
