namePotassium [Mass/volume] in Red Blood Cells
descriptionAmong its many physiological functions in the body, potassium controls heart function and subsequently blood pressure. Patients with hypertension and those who may develop it have been found to have lower intracellular potassium levels than patients with normal blood pressure. The measurement of intracellular potassium is a useful marker to predict the risk, development and treatment of patients with hypertension.( http://pubs.acs.org/doi/pdf/10.1021/ac900776d) Calculation: Hct= a(1-R)/a+R(b-a) where 'a' is the fraction of water in the plasma (typically a=0.93), 'b' is the fraction of water inside the erythrocytes (typically b=0.65), 'R' ratio of sodium ion concentration measured before and after lysing the RBCs

componentPotassium
propertyMCnc  =  Mass Concentration
timePt  =  Point in time:  To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements.
systemRBC  =  Erythrocytes
scaleQn  =  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
