Every lab determines it own exact range. It is usually somewhere around 3.5 to 5 mEq (or mMol) per liter.
3.6
The normal concentration of potassium in the serum is in the range of 3.5 to 5.0 mM
Normal potassium level is 3.5-5.5 and the normal range for magnesium is 1.5-2.5 although there may be variations depending on the source book that you check, these are the general norms for serum potassium and magnesium.
That is within the normal range for serum potassium levels, which range from 3.5-5.0 mmol/L in an adult.Newborns and children are different.Newborn: 3.7-5.9 mmol/LInfant: 4.1-5.3 mmol/LChild: 3.4-4.7 mmol/LReferenceDavis' Comprehensive Laboratory and Diagnostic Handbook with Nursing Implications, 4th edition
The normal levels of serum potassium are 3.5-5.0 mM
25 to 100mmol/L
Normal levels range between 3.5-5.2 so you have nothing to worry about at this point.
Normal potassium
According to Medline Plus, the normal range for potassium in adults is 3.7-5.2mEq. 6.7mEq is cause for concern and you should seek advice from a physician or hospital.
What is the normal range?
At standard temperature and pressure, potassium is a solid.
No
Potassium is actually used in cardiac tissue so any increase or decrease will result in ECG changes. Increased potassium will result in tall tent like T waves on an ECG whereas decreased potassium will result in flattened T waves. Often patients will get labs drawn to ensure their potassium levels are within normal range and to determine how much supplements if any you need.
