Reference Range
Cryoglobulins do not have a consensus reference range.
Serum cryoglobulins in most individuals are in low concentrations (100-300 mg/L) among the high concentrations (60,000-80,000 mg/L) of normal serum proteins.
The cryocrit (percentage of packed cryoglobulins referred to total serum after centrifugation at 4°C
) is the most practical and clinically useful parameter to predict a patient’s clinical outcome; 1% or more of cryocrit is abnormal.
