The positive Chvostek's sign and tremors suggest neuromuscular irritability, which is associated with a low magnesium level even if the serum calcium level is low normal. Low phosphate and low potassium will also cause neuromuscular irritability, but they do not cause a positive Chvostek's sign. Elevated sodium levels are associated with dehydration and hypernatremia, which do not cause tremors or a positive Chvostek's sign.
