Specimen Requirements

Sample Type

Collection Container

Alternate Collection Containers

Midstream urine (follow the instructions in the MSU Kit), Straight Catheter urine, Cystoscopy urine, Suprapubic Aspirate

C&S Container

If transport to the Microbiology laboratory will take greater than 12 hours, use a Boric Acid Container.

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.

Minimum Volume

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.


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

Do not send Foley catheter tips.
