Cryotherapy precautions include a high level of which blood protein that clumps in the cold?

• A. High level of cryoglobulin
• B. Cold urticaria
• C. Raynaud's
• D. Hemoglobinuria

Answer: (A)

Cryoglobulins are immunoglobulins that precipitate out of solution when they are cooled. In cryotherapy, the treated tissues are cooled, so these proteins can clump together in the blood vessels of the skin and surrounding tissues. This can block small vessels, reduce blood flow, and cause tissue ischemia or injury. Because of that risk, knowing a patient has elevated cryoglobulins or cryoglobulinemia is important before using cryotherapy, and precautions or alternative treatments may be needed. Cold urticaria is a skin reaction to cold exposure rather than a protein that clumps in the cold. Raynaud's involves vasospasm of the digits in response to cold, not precipitation of a protein. Hemoglobinuria relates to red blood cell breakdown or cold-induced hemolysis in some conditions, not to cryoglobulins themselves.
