blood urea nitrogen purpose

a waste produced from protein breakdown in the body that is normally excreted through urine.

low values shows poor liver function or malnutrition, and high values suggest that the kidneys aren’t removing this waste properly.

may also be high if there is hypovolemia in the blood

creatinine purpose

a waste product of protein and muscle breakdown and is excreted through urine

low levels caused by muscle loss, malnutrition, and pregnancy, since there is less to breakdown

high levels caused by improper filtration by the kidneys

may also appear high due to hypovolemia

creatinine clearance purpose

a urine test that tests levels of this chemical compound. low levels suggest improper kidney function, due to low waste removal

magnesium purpose

supports nerves and muscles, immune system, bone strength, and steady heartbeat. if K is consistently low despite interventions, this may be the cause

potassium purpose
