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.

Collection and Shipping Requirements
Refrigerate all stool specimens. A specimen refrigerator is located in the hallway outside the Laboratory for after-hours specimen drop off.

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
Routine stool culture consists of investigation for the following organisms: Aeromonas, Campylobacter, E. coli 0157:H7, Salmonella, Shigella and Yersinia.
Investigation for Vibrio or C. difficile toxin must be specifically requested.
