| name | Sodium [Mass/volume] in Red Blood Cells | ||
| description | Measurement of intracellular sodium is performed in concert with the intracellular measurement of potassium. Intracellular potassium is a marker for the development of hypertension. The measurement is based on the fact that intracellular sodium is very low compared to plasma sodium. When the cells are lysed in order to measure the intracellular potassium, the hematocrit of the sample is determined by the dilution of the plasma sodium by the now free intracellular sodium.

| property | MCnc = Mass Concentration | ||
| time | Pt = Point in time: To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements. | ||
| system | RBC = Erythrocytes | ||
| scale | Qn = Quantitative: The result of the test is a numeric value that relates to a continuous numeric scale. Reported either as an integer, a ratio, a real number, or a range. The test result value may optionally contain a relational operator from the set {<=, <, >, >=}. Valid values for a quantitative test are of the form "7", "-7", "7.4", "-7.4", "7.8912", "0.125", "<10", "<10.15", ">12000", 1-10, 1:256 | ||
