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

For investigation of hypoglycemia, to assess ability to access glycogen stores. Fasting glucose is measured prior to administration of 1mg glucagon IM/SQ. Glucose measurements are repeated at 10 minutes and 20 minutes following glucagon administration.
