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
Hemoglobin may be falsely lowered if blood has been allowed to clot prior to analysis. Send a CBC prior to making decisions regarding transfusion.
Direct ISE methods are less susceptible to negative interference caused by excess lipid or protein in the sample.
Hemolysis cannot be assessed in whole blood samples and may lead to spuriously elevated potassium values. Confirm potassium with a plasma sample if clincally indicated.
This glucose method has a positive interference with mannose, xylose, and galactose. Order a plasma glucose to confirm any result which does not correlate clinically.
This lactate method has a positive interference with glycolic acid, the major metabolite of ethlyene glycol. To confirm an elevated lactate, order a plasma lactate (LACT).
Elevated carboxyhemoglobin or methemoglobin is automatically reported on any RMP order, if that hemoglobin species is present.
