what is your guess ? 🤔
Case :
A 90-year-old man 👨🏻🦳was admitted after a house fire. Physical examination revealed burns and soot all over his face. Laboratory tests showed blood pH 7.2 and carboxyhemoglobin 23.4% (reference interval 0 –1.5%), consistent with smoke inhalation.

Considering his clinical features and laboratory results, the diagnosis was carbon monoxide and cyanide intoxication. He was treated with hydroxycobalamin injection (Cyanokit®) and hyperbaric chamber sessions and recovered rapidly.
The patient’s plasma sample appeared bright pink in color and was associated with a negative hemolysis index.
QUESTIONS TO CONSIDER✍🏼
1. What caused the plasma color in this case?
2. Why was cyanide poisoning in the differential?
3. Are there any interferences with laboratory tests to consider?
