The lab reports that the urine osmolality is 150 mOsm/kg, which means the urine is overly dilute (too much water in the urine). The blood osmolality is 300 mosm/kg, meaning the blood is overly concentrated (too little water in the blood). The lab also reports that his blood glucose is completely normal.

Transcribed Image Text:Case 3: The Parched Professor
Your last call is to the aid of Professor Purple. Three witnesses are present from whom to take statements.
Witness statements:
I Mr. Olive: "I swear that I saw him drink a full glass of water every half an hour today. He kept saying how thirsty
he was!"
I Mrs. Blanc: "He must be going to the... well, you know, the little boys' room, two or three times every hour!"
I Ms. Feather: "He's been saying lately that his mouth is dry and that he feels weak. Personally, I think he's just not
following a healthy diet! He should be drinking some of my herbal teas!"
Based upon the witnesses' statements, what are your initial thoughts? Does one hormone come to mind that could
produce these effects?
You interview Professor Purple and collect blood and urine specimens to be sent off to the lab for analysis. The lab
reports that the urine osmolality is 150 mOsm/kg, which means the urine is overly dilute (too much water in the urine).
The blood osmolality is 300 mOsm/kg, meaning the blood is overly concentrated (too little water in the blood). The lab
also reports that his blood glucose is completely normal. What is the significance of these clues?
Based upon the witness statements and the laboratory analysis, what is your final diagnosis? (Hint: Think of the hormone
that is supposed to trigger water retention from the kidneys. Is there a disease where this hormone is deficient?)
