MEASURAND : Clinical markers in human serum
Mass fraction of Na in human serum
The key comparison reference value, xR, is calculated as the median of the participants’ results. Its standard uncertainty, uR, is computed as explained in section 5.2 of the Final Report.
(*) Nist excluded in the calculation
| The degree of equivalence of each laboratory i with respect to the key comparison reference value is given by a pair of terms, both expressed in mg/kg: Di = (xi - xR) and Ui, its expanded uncertainty (k = 2) where Ui = 2(ui2 + uR2)1/2 |
