A patient complains of constant thirst, excessive passing of urine and low blood pressure. When the doctor checked the patient's blood glucose and blood insulin levels, the levels were found to be normal or slightly low. The doctor diagnosed the condition as diabetes insipidus. But he decided to measure one more hormone in the patient's blood. Which hormone does the doctor intend to measure?
The doctor intends to measure Vasopressin or Antidiuretic hormones (ADH) because low levels of these hormones can cause excessive passing of urine and low blood pressure in humans.
