Sample Type
Collection Container
Alternate Collection Containers
Tissue (Liver)
Tissue samples are to be collected in an acid washed, plastic screw cap vial.
Collect specimen on sterile gauze and wrap it with another sterile gauze and place in a sterile specimen container. Ensure specimen doesn’t touch the specimen container walls.
Add on stability
This is the length of time after sample collection that this analyte is stable. Test can be added to a previously collected sample if the time since collection is less than the add on stability time.

Measurement Uncertainty (MU)
Every laboratory value is an estimate of the true concentration of substance. MU is the 95% confidence interval around that estimate. 95% of the time, the true concentration will be within the range of the reported value ±MU. This value is based on analytical variability (precision) and does not reflect other factors such as sample collection and handling which may also affect the result.
Example
Reported sodium = 140 mmol/L
Sodium MU = 1%
Expanded uncertainty = 140 mmol/L ± 1% or 140mmol/L ± 1.4 mmol/L
Interpretation - the true value of sodium in the sample is in the range 138.6-141.4 mmol/L, with 95% confidence.
Measurement Uncertainty
Liver for iron, copper and/or zinc analysis. Only done when requested by a pathologist.
