The chem panel or smac checks for eletrolytes like sodium, potassium, and chloride.
Sodium, potassium, chloride would fall under U&E testing (Urea and Electrolytes).
electrolytes
sodium and potassium
Potassium is a mineral used to help lower blood pressure and moderate electrolytes in the body. Sodium is basically salt, and large quantities in the body creates high blood pressure. So, it is important to have sufficient potassium, or Vitamin K, and lower sodium or salt. Potassium is good. Too much for sodium is bad.
mineralocorticoids
Two important electrolytes found in blood plasma are Na+ (sodium) and Cl- (chloride).
Sweat is largely water. There is no salt in human sweat. Human sweat tastes salty because it contains potassium chloride, not sodium chloride. Salt's main function is as a fluidic electrolyte in blood tissue, and is used in muscle contraction causing calcium and potassium to shift in the muscle cells, the heart muscle cells as well, allowing for engery to be used. Salt is regulated by nephrons of the kidneys (1 million in each) and is excreeted into the urine. High blood sodium/salt levels usually result in high salt content in urine. Sweat and urine are drinkable fluids in the absence of water and can save your life in a crisis.
