Potassium [Mass/volume] in Red Blood Cells

Active

Term Description

Among 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

Part Descriptions

LP15098-4   Potassium
Potassium (symbol K from Latin:kalium) is a key chemical element involved in neuron function and influencing osmotic balance between cells and interstitial fluid. Depletion in potassium levels results in deficient fluid and electrolyte balance in the body as well as various nervous and cardiac dysfunctions. Studies suggest diets high in potassium can reduce the risk of hypertension and possibly stroke. Foods rich in potassium include parsley, dried apricots, potatoes, bananas, avocados, soybeans, and bran, as well as most fruits, vegetables, meat and fish. Overall, clear cases of potassium deficiency are rare in healthy individuals. Copyright Text is available under the Creative Commons Attribution/Share-Alike License.

LP15098-4   Potassium
An element that belongs to the alkali group of metals. Symbol K, atomic number 19, and atomic weight 39.10. It is the main cation in the intracellular fluid of muscle and other cells. Potassium ion is a strong electrolyte and it plays a significant role in the regulation of fluid volume and maintenance of the water-electrolyte balance.
