Mr. Smith is 60 years old. He was diagnosed with a prostate cancer five years ago. Over the past few days, Mr. Smith has been feeling weak and increasingly tired and has also been suffering from a headache that did not respond to over-the-counter medications. He scheduled an appointment with his physician.
His physician performed a physical examination and recommended a battery of laboratory tests and imaging procedures.
The table below shows Reference values in the right-hand column. These values reflect the normal range of values for patients without disease or illness. The center column reflects the resulting values for medical test results obtained for Mr. Smith.
Take note whether Mr. Smith’s values are within normal limits.

The following week, Mr. Smith returns to his physician with the same complaint of weakness and a new complaint of shortness of breath. His blood pressure is 160/100 mmHg. MRI reveals metastasis of prostate cancer to osseous tissue. Abdominal CT shows obstruction of intestine due to nodular enlargement of adrenal glands.
