A potassium rich diet may reduce blood pressure by helping the body remove excess sodium. Kidney disease is one of the reasons for the high potassium level. Your body should maintain a specific amount of potassium in the blood ranging from 36 to 52 millimoles per liter mmoll. Potassium is released from platelets during clotting. These differences are due to the lower muscle mass in these groups. A whole body skeletal muscle sm.
Kg mass estimation model based on total body potassium tbk. Total body potassium measurement by whole body counter for estimation of lbm. It is encountered in 20 of patients. The kidney controls the level of potassium in body fluids by controlling the amount of potassium to be excreted. Why would i get this test. The counter consisted of six nai tl detectors that ranged from 76 to 127 cm in diameter and from 76 to 127 cm thick.
Potassium is the eighth or ninth most common element by mass 02 in the human body so that a 60 kg adult contains a total of about 120 g of potassium. Its important to note. Potassium can be measured in serum plasma lithium heparin or heparinanticoagulated whole blood. Mmol measured by whole body 40 k counting wbc was developed sm 00082tbk and validated in adults in a previous study. Thus a 70 kg adult man contains 135 g potassium. Body potassium concentration is 4555 mmol kg 1 of body weight.
It is unknown whether the adult tbk sm prediction model is applicable for pediatric use. Normal level 35 55 mmoll. The normal range of potassium level in the body is 32 mmoll to 52 mmoll. High sodium levels can elevate blood pressure especially for people whose blood pressure is already high. Your body needs potassium to function normally. The body has about as much potassium as sulfur and chlorine and only calcium and phosphorus are more abundant with the exception of the ubiquitous chon elements.
Therefore plasma and whole blood concentrations are 0107 mmoll lower than those in serum. Whole body potassium was measured by counting 40 k in a shadow shield whole body counter. Hypokalemia is defined as a serum potassium level of less than 35 mmoll. 21 medium in which measured 1. Its vital to the functioning of nerve and muscle cells. Patients are usually asymptomatic but severe arrhythmias and rhabdomyolysis can occur.
If the potassium level is increased above 60 mmoll patient requires medical intervention. Women have 3540 mmol kg 1 of body weight and in the elderly and children body potassium concentration is also lower than that for young men. A normal potassium level is between 36 and 52 millimoles per liter.
