A potassium test is used to detect abnormal concentrations of potassium, including high potassium (hyperkalemia) and low potassium (hypokalemia). It is often used as part of an electrolyte panel or basic metabolic panel for a routine physical. So the test in done in a SSP, serum separator tube, with glass/silica particles for enhanced coagulation. The tube stopper top can be gold or red tiger.
